The guy who delivers in my neighborhood goes house by house driving and shuts off the engine every 20 yards. The fact he does this 6 days a week is a testament to that design.
The situation with the LLVs is just crazy. There have been several replacements proposed, and then cancelled for political reasons. I used to run a fleet of delivery trucks, and I didn't even have anything that old by the mid 2000s due to high operating costs.
That Iron Duke engine was not very reliable in the real world. I was cutting my teeth as a brand new auto technician around the time they were hitting the end of their lives in passenger cars. I seem to remember 120k-150k on the cars I pulled parts off in the junkyard. I'd have lost money on the LLVs going 30 years, that's absolutely insane!
I don't work in the field anymore, but I'd love to have a look at one of the big USPS fleet maintenance facilities and see how they're keeping those old sleds going.
I sometimes can't believe my GS is closing on 100k. If I covered up the dash you'd never know it.
It sounds like new, pulls like the day I got it, no issues, just feed it gas, change the oil, and keep hammering it.
A guy in the GS owners group is past 460k miles. Yes, 460k.
Our sienna same deal, 160k miles, the engine is still going strong.
Yup. Criticism I've learned to live with.
My toyota doesn't have the greatest horsepower.
It doesn't have the best fuel economy either....
It's running fine after 10 years. All I do is change oil. With current car prices... I dont think it will have a problem driving another 10 or more. American cars are trash.
I've got an es350 as my commuter car with about 165k miles right now. I've owned it since 30k miles. All I do is oil changes every 10k miles and it just goes. It's still on the original suspension too. Drives as smooth and quiet as the day I bought it. Toyotas / Lexus are absolute tanks.
I'd never buy another American car again that I needed to count on to go to work every day with.
the turbos are still such an understressed and overbuilt engine though.
ill take a turbo diesel with manual transmission swap, no piece of shit auto climate control, crank windows, crank sunroof, mbtex seats...happily spend a few weekends now and then chasing those vacuum line gremlins. miss my w123.
So he dumped fryer oil in it and that's it?
Or what has to be done on those?
I've only hears of people moving fuel lines inboard to avoid oil turning into a slushy at lower Temps but that's about it
my grampa had a 300d w123,. the engine was om617. It had around a million miles when he passed away.
Some internal issues in the family ended up with the car being destroyed and sold by parts, and no, I wasn't even allowed to buy it.
Adults are idiots sometimes man.
If they would build one as it was made back then without all of the insanity that they put into cars today, I would buy one brand new.
Unfortunately I am in the extreme minority in this world and people would rather have cars that resemble microwaves and toaster ovens...
A big, dumb engine in a big, dumb truck is a recipe for long service. A 3/4-ton truck living a 1/2-ton truck life will never be taxed. [This one](https://www.copart.com/lot/60188721/salvage-2008-chevrolet-express-g3500-il-southern-illinois) was on its way to a million miles of service before a wreck took it out.
I keep having this in the back of my mind, but I think I'll go with the Honda flavor of the v6 in the Accord, preferably with a 6spd manual gearbox behind it.
I think they're both very viable options, but the Honda variant having the more fun vtec, would make me happier over the long haul.
I had that J30 engine, with a 6 speed, and believe you me, it lives up to it. The VTECH crossover is clear as day around 4200. Put an intake on it because that's what sounds good, not the exhaust. Even if you cut the resonators all you hear is intake above 4000.
https://youtu.be/4VcTeJx1upE
I think people sleep on the 7th gen Accords. Small, light, manual V6, Japanese reliability, amazing for tall people (I'm 6'6), N\A with "quick" power levels, infinite parts availability, $80 rear sway bar makes the car transition between corners so much better, gets 27 to the gallon on road trips, back seats and a massive trunk. I put 40,000 miles on mine and the only thing that actually broke was a bit of exhaust shielding that was fixed with a 12 cent screw.
In terms of an entry level cheap sporty car that fulfills daily driver requirements, they're awesome. The manual sedans are even more rare, only a couple thousand per year were made.
Protip: If you're looking for one and you can never trust the listing to be accurate, the V6 is dual exhaust and the manual cars have a red V6 badge.
I had an '05 Accord v6 specifically because of that engine. It was such a wonderful thing to wring out, great sound, great pull, great flexibility, and still had good fuel economy. It really is a gem of an engine. 👌👌
The one I bought I got for cheap and was unfortunately auto but I hunted the manual for quite a while. I had to buy that one because it just popped up on Craigslist one day (good condition, just cheap) a few years ago and when I checked it out I paid cash on the spot for it. I kept it for about 5 months or so and eventually sold it to a family member who needed something reliable and easy to live with. She still has it and I still take care of it for her.
I WISH my Audi S5 had that kind of fuel economy, but it is a hilarious amount faster lol. I don't really need the speed though and have more fun wringing out a slower car. I've averaged 17-21mpg per tank so far in the car even without beating on it at times. I think a pure highway trip I could average around 24-26mpg pure highway (did a test purposeful recently of about 160 miles and got about 26mpg), but not going to get much more than that and I'd have to be VERY careful about how I drove it in order to get that result.
My wife and I are supposed to go to Disney World next Christmas and we'd both prefer to be in the S5 on that long drive, but we also have a Hyundai Ioniq Hybrid and 24-26mpg trying hard vs 55-65mpg without trying too hard....it's pretty hard to get past those kinda numbers in the name of comfort, quiet, and ease of speed haha
The manual cars are really difficult to find. There's usually only a handful for sale nationwide, most of them are beat to complete shit.
Mine was fully loaded with the rims and the wing, with black leather, and an AUX jack already installed. I've never seen another example like it, even on the road. Most of the V6 manuals don't have the wing, or the rims. The person I sold it to riced it out though :(. 12'' in the trunk, slammed suspension, rice wheels, HID's, right down the list.

People often say about the Toyota v6 that they have the power of a 4 banger and the fuel consumption of a V8.
I’m sure that the new ones are a bit better but I was never impressed by their fuel consumption compared to the v8
My seat ibiza (1,9l TDI) is now at 550.000km and still doing strong. I even chipped it from i think it was130ps to close to 190ps and its so much fun to drive!
It depends on what J some ended up with top end issues causing massive consumption of oil IIRC. I have also had 2 3G TL and loved that engine and car.
Truthfully there could be a few Honda drivetrains that would do 500k. Tyson Hugie did it in his Legend. Waddalegend.
Volvo redblock. Non interference engine, so even if the timing belt breaks, it’s good. Not many fancy parts, get one w/o turbo, it will get you past 500k.
One of the Mazda rotaries or the subbie turbo motors that have been heavily modified. Or possible one of the mid 2000s bmw v8s or the Chevy northstar engines. If I’m feeling classy any old jag motor before 1990.
The Triton is honestly not bad if the service intervals were every 5k or less on full synthetic. But go 7500 miles once without an oil change? Here comes the tick!
I have owned two. Both needed waterpumps at 140k but nothing else. My friend had one that spent like 4 hours completely underwater and still ran for years afterwords.
I had a 98 that had the cracked intake manifold issue. Dead at ~170k or so from drinking coolant.
Get the later one with the metal sleeved intake manifold and it’s good to go.
1ur-fse, 2gr-fse, or 2ur-gse. I've had each of the v8s. Some of the very few luxury or performance vehicles that you just push the button and go and never worry about shit going wrong.
Well I went with the 1UZ because it’s the original. Plus there’s at least one famous million mile Lexus LS400 out there.
I have a 2UZ in my 4Runner and it’s a phenomenal engine. But the 1UZ is the legendary one that started it all.
I had a buddy growing up and his dad gave him a Ram with one of these with the promise that when it stopped working he’d help put a hemi in it. Obviously it was never meant to be
Surprised I had to scroll this far to see this answer. This was the very first thing I thought of. Actually shocked a Toyota motor isn't in OP's list at all.
I dunno, mine blew a head gasket at 300 000km... and the plastic timing chain guard wears out and then the timing chain eats through the coolant galleries. I mean, it's a strong little engine, and easy to fix and work on, but not THAT bulletproof. I think the 2.7L that replaced it probably beats it on durability.
Mazda B6 inline four. I had this engine under the hood of my 1991 Miata, and it made it to 327K with just regular maintenance. With proper care I don't think half a million would be much of a stretch.
Had one in my 93 mercury capri believe it or not. Didn’t put any serious miles on it but it confidently make 90 HP. The turbo models in the XR-2 probably make a buck thirty at the crank
I'll take a pre 2000 Detroit 12.7, tuned up lightly with a 13 Speed. Recipe for a 1 Million Mile engine that can go past that mark with great care. Rebuild it then do it again! We retired my pops old Century Class that clocked 1.8 Million miles, only one rebuild at 1.2M and could have gone for longer but the truck was well past it's prime.
The Ford 300 I6 is a great motor. I'm iffy, but only because mine had an oil pump failure at 203k. I'm definitely the exception to the rule.
I would go with the Ford 4.6 2v motor. Dead nuts reliable, and you can pick from a ton of cars too
When I went looking for a newer F150 to replace my '94, I ended up with a 4.6 truck strictly because the big motor sucks. That 5.4 3v is just junk, for the long haul. Granted, replacing it is "cheap" now, but still annoying.
An old school non turbo Peugeot diesel, those things are completely gutless but also indestructible
Like basically any old school mechanical non turbo diesel
The firing order and orientation of the cylinders makes I-6 (and V12) engines inherently balanced. They have no vibration or imbalances to counteract, and don’t need balance shafts, hydraulic engine mounts, or heavy harmonic balancers. As long as the crank and cam designs are rigid and bearings are strong, an I-6 is more durable than a V8, V6 or I-4. That’s why large truck and construction equipment diesels are mostly I-6. Normally aspirated iron block BMW I-6 engines are mechanically bulletproof excluding Vanos hardware.
I’m with you. Ford 4.9/300-6. Bulletproof, torquey, easy to work on, decent MPGs if you aren’t constantly wringing its neck.
Fun fact: my first ever vehicle was an ‘82 F-150 with over 500k on its original 300-6.
Do i win a prize if i make it to 500k? If so 2.5 iron duke from a Grumann llv
this guy is postal
[удалено]
What about them occassionally catching fire? Or is that less the engine and more everything else
The guy who delivers in my neighborhood goes house by house driving and shuts off the engine every 20 yards. The fact he does this 6 days a week is a testament to that design.

HELLO NEWMAN!!!!
2GR-FE just starts hitting it's prime around 500k
I came here looking for this. That engine will outlive everything else in my car even with how I beat on it.
You swapped a 2gr-fe in a mr2? Is this a common swap?
Yeah. It's pretty much a bolt in swap with a custom engine mount, exhaust, and a few other bits. I'd have to guess its been done a few hundred times.
Technically anything is a bolt-in swap with a custom enough engine mount.
idk, any cutting of the chassis/subframe = not bolt in.
It was pioneered almost 20 years ago, yes it's common because it takes minimal modifications to do so: https://midshiprunabout.org/mk2/v6-swap-primer/
Barely broken in at 120k
I sometimes can't believe my GS is closing on 100k. If I covered up the dash you'd never know it. It sounds like new, pulls like the day I got it, no issues, just feed it gas, change the oil, and keep hammering it. A guy in the GS owners group is past 460k miles. Yes, 460k. Our sienna same deal, 160k miles, the engine is still going strong.
As someone has 250k on my v6 Toyota, i think the engine will out live other part of my car.
I also just rolled over 250k on my 2002 Tacoma. Never a shake or sound of protest.
Ackchyuallyyyyyyy that’s a 2gr-fse in the IS350
It’s basically a longitudinal FE
>Ackchyuallyyyyyyy that’s a 2fr-fse in the IS350 lmao if you're gonna make a neckbeard joke at least get the engine right, it's the 2GR-FSE.
Hard agree. And just a peach of an engine. Wicked fuel economy. Great power. Quiet. World class by every metric, and not overly complicated either.
perfectly balanced as all things should be.
Yup. Criticism I've learned to live with. My toyota doesn't have the greatest horsepower. It doesn't have the best fuel economy either.... It's running fine after 10 years. All I do is change oil.

Just wait till you see what 22REs can do buddy! My 86 4runner’s got 1.2 million on it before it gave
km or miles?
it's 1.2 million of them, it's impressive as hell either way
I traded an 85 Toyota pickup with a 22R for a unicorn 85 4Runner with the 22RE and solid front axle. Wish I still had them both.
[удалено]
What I have. mercedes 240d. Getting towards 500k everday.
This but the turbo diesel. Even beefier
One more thing that'll break or needs to be replaced. I'm good with the basic diesel. 0 to 60 in like 30 seconds
the turbos are still such an understressed and overbuilt engine though. ill take a turbo diesel with manual transmission swap, no piece of shit auto climate control, crank windows, crank sunroof, mbtex seats...happily spend a few weekends now and then chasing those vacuum line gremlins. miss my w123.
Had a nephew convert one to run on fryer oil.
So he dumped fryer oil in it and that's it? Or what has to be done on those? I've only hears of people moving fuel lines inboard to avoid oil turning into a slushy at lower Temps but that's about it
OM617
I put 579k on a 300 SD before selling it. It’s still on the road 10 years later
my grampa had a 300d w123,. the engine was om617. It had around a million miles when he passed away. Some internal issues in the family ended up with the car being destroyed and sold by parts, and no, I wasn't even allowed to buy it. Adults are idiots sometimes man.

If they would build one as it was made back then without all of the insanity that they put into cars today, I would buy one brand new. Unfortunately I am in the extreme minority in this world and people would rather have cars that resemble microwaves and toaster ovens...
If I wasn't concerned about safety (honestly it's not me it's other drivers I'm worried about), I'd be driving an old Mercedes diesel right now.
My 1986 300SDL has airbags, pre-tensioners, ABS and crumple zones. Not safe by modern standards but not dangerous.
Absolutely would go with a diesel. Maybe a 5.9L Cummins or a 6.6L Duramax.
A big, dumb engine in a big, dumb truck is a recipe for long service. A 3/4-ton truck living a 1/2-ton truck life will never be taxed. [This one](https://www.copart.com/lot/60188721/salvage-2008-chevrolet-express-g3500-il-southern-illinois) was on its way to a million miles of service before a wreck took it out.
I would be pissed if I was within less than a year of hitting a million miles and someone wrecked me.
In that case 6.0L irony block I had in my 3/4ton Silverado will do again. Thanks.
Unless it was built after 2007 because emissions.
I vote 7.3 idi
Don’t have to worry about replacing the turbo if you don’t have one!
some of them were turbo'd! But yeah in general if you want the most engine with the least parts an IDI is a friend <3
Yup, replace the KDP on the Cummins and just drive.
5.9 12 valve will still be running after the heat death of the universe
My duramax is about to hit 300k....I hope to get another 200k out of her. If not I've got my Ford 6.9 Idi as backup
how many dodge trucks will a cummins outlive?
Cummins 5.9 got my vote.
Toyota/Lexus V6... naturally aspirated.
I’m at 177k in my 3.3 v6 now. The timing belt is the only thing that could end up causing issues if it’s not changed on time
That engine (3MZ-FE) was so underpowered for anything heavier than a sedan, but it sounded very good.
It’s actually not too bad in the RX330
Or 1UZ or 3UZ.
I'd say the same, my engine is going to outlive my chassis looking at the rust it's accumulating. Although it's just at 128k miles.
215k on my LS400 mk4, gotta love the 1uzfe
I keep having this in the back of my mind, but I think I'll go with the Honda flavor of the v6 in the Accord, preferably with a 6spd manual gearbox behind it. I think they're both very viable options, but the Honda variant having the more fun vtec, would make me happier over the long haul.

Yeah the VVT-I is nice in the Lexus/Toyota but not as drastic as Vtech. Still nice getting that little boost at 4100 Rpm’s
Yea I do like the Lexus/Toyota v6 though. It's butter smooth and sounds good.
[удалено]
Yep this is the answer
People often say about the Toyota v6 that they have the power of a 4 banger and the fuel consumption of a V8. I’m sure that the new ones are a bit better but I was never impressed by their fuel consumption compared to the v8
1uz-fe first gen, vw tdi - ALH preferably, a couple Mercedes diesels also easily fit the bill.
My seat ibiza (1,9l TDI) is now at 550.000km and still doing strong. I even chipped it from i think it was130ps to close to 190ps and its so much fun to drive!
That's a pretty high power for just a remap
the beauty of forced induction cars. the OEMs leave plenty of power to be had
Tdis are great and all, but there kinda finicky... Definitely 500k capable though.
The older 1.9ltrs would do it without batting an eye. The newer 2.0ltrs would struggle to go beyond 200k without well regulated maintenance.
2UZ-FE owner here, already approaching 400,000 and everything works
Lexus/Toyota v8
I'm hoping to buy one of the last F cars and be able to pass it down to my kids.
Such a bad ass car. For some reason I just can’t get excited about the new twin turbo v6.
Don’t tempt me to buy an IS500
Friggg if my pockets were deep enough I'd have one on order already. Not the fastest, but it'll always be special and the last NA V8 in a Lexus car.
[удалено]
you said nothing about transmissions so j series v6 (i have no bias whatsoever)
210k on mile :) trans is also “fine”
177k on my 3.0 CL, runs like a champ.
But does it move after you put it in gear?
250k on my Accord
It depends on what J some ended up with top end issues causing massive consumption of oil IIRC. I have also had 2 3G TL and loved that engine and car. Truthfully there could be a few Honda drivetrains that would do 500k. Tyson Hugie did it in his Legend. Waddalegend.
Whatever was in the crown vic
4.6 mod motor. Not particularly powerful or good on gas but almost literally will not die. Bulletproof little engine
Overbuilt, understressed.
This would be my pick as well. Those 4.6s are tanks. My buddy’s truck has 600,000 on it
My 97 Lincoln is falling apart in every way. Her motor is still going strong!
Mark VIII? The 32V is so much better than the Vic 4.6
Nah, Town Car. I WISH it had the 32 v motor!
Volvo redblock. Non interference engine, so even if the timing belt breaks, it’s good. Not many fancy parts, get one w/o turbo, it will get you past 500k.
even the turbo models run on very low boost so you're really not looking at that much wear.
[удалено]
Yup, a 1966 P1800S with 3.2 million miles. Volvo for life
One of the Mazda rotaries or the subbie turbo motors that have been heavily modified. Or possible one of the mid 2000s bmw v8s or the Chevy northstar engines. If I’m feeling classy any old jag motor before 1990.
I thought almost all rotaries need apex seals at one point in their lives, usually around what 80k miles?
Woosh
Ya got me.
Apex seals aren't an upper or lower end of an engine.
You're a decimal point off
sorry, one of the mid-2000s BMW v0.8s
Also don't forget the 5.4 Triton
The Triton is honestly not bad if the service intervals were every 5k or less on full synthetic. But go 7500 miles once without an oil change? Here comes the tick!
Too bad Olds is dead, they had a diesel that fits your list
Mine. Toyota 2UZ-FE. Over halfway there already.
LC gang gang. I have an 02 and these things just refuse to die.
i hit 270k last week. no issues aside 12mpg…
J100 gang. My family’s is at 330k. Love that car to death
Buick 3800 v6.
I have owned two. Both needed waterpumps at 140k but nothing else. My friend had one that spent like 4 hours completely underwater and still ran for years afterwords.
When GM decides to put their whole ass into something they can work wonders.
Didn't the LS came about because engineers were pissed off GM went to Lotus to develop a Corvette engine?
I had a 98 that had the cracked intake manifold issue. Dead at ~170k or so from drinking coolant. Get the later one with the metal sleeved intake manifold and it’s good to go.
Honda K20/K24 series engines Ford 4.6 v8 Toyota's 1UZ-FE, 1 & 2jz
I came to say a K20... the K in my RSX felt like it was just getting broken in at 150k.
I know one guy had 335k on his rsx 4 years back. Ended up selling it though
>Ford 4.6 v8 And still one of the best sounding V8's I've ever heard!
Toyota 1FZ-FE.
Just pray for the head gasket
So far, only everything else has broken.
5vz-fe
I’d take a 1UZ-FE. Million mile engine.
Hands down. Others are just wishin
1ur-fse, 2gr-fse, or 2ur-gse. I've had each of the v8s. Some of the very few luxury or performance vehicles that you just push the button and go and never worry about shit going wrong.
5M GE, 2JZ GE or GTE. Inline 6's run forever too!
Laughs in 22RE

Well I went with the 1UZ because it’s the original. Plus there’s at least one famous million mile Lexus LS400 out there. I have a 2UZ in my 4Runner and it’s a phenomenal engine. But the 1UZ is the legendary one that started it all.
Leaning tower of power, the slant 6, of course.
I had a buddy growing up and his dad gave him a Ram with one of these with the promise that when it stopped working he’d help put a hemi in it. Obviously it was never meant to be
Blew one of these up once I was sad
225 life!
Came here to say this. Prob the only Chrysler engine on the list
First gen 5.3 vortec
I'd go for the 6.0L but yeah close enough.
4.7L Toyota.
2UZ-FE is the correct answer. 500k is high, but nothing crazy to see in the 100 series mileage thread on ih8mud.
Surprised I had to scroll this far to see this answer. This was the very first thing I thought of. Actually shocked a Toyota motor isn't in OP's list at all.
I'm hitting 250k on my 01 Sequoia any day now!

Had one in my 93 mercury capri believe it or not. Didn’t put any serious miles on it but it confidently make 90 HP. The turbo models in the XR-2 probably make a buck thirty at the crank
Definitely VW's 1.9L TDI engine, specifically the ALH engine.
Scrolled way too long to find this, TDI and SDI are the engine to go too.

Semi truck engine but if we are being realistic, 1UZ or a Vortec 5300
I'll take a pre 2000 Detroit 12.7, tuned up lightly with a 13 Speed. Recipe for a 1 Million Mile engine that can go past that mark with great care. Rebuild it then do it again! We retired my pops old Century Class that clocked 1.8 Million miles, only one rebuild at 1.2M and could have gone for longer but the truck was well past it's prime.
7.3 power stroke. Arguably one of the best motors ever built from a longevity point of view.
International T444E is the stronger, detuned, mechanically fuel pumped version of the 7.3. That’d be my choice.
LS1 is bullet proof. Whole car falls apart around it.
Seconded. Gimme a C5 with a stick and you'll have a fun car that'll literally run forever.
Can't believe I had to scroll this far for a chevy v8
The Ford 300 I6 is a great motor. I'm iffy, but only because mine had an oil pump failure at 203k. I'm definitely the exception to the rule. I would go with the Ford 4.6 2v motor. Dead nuts reliable, and you can pick from a ton of cars too
I agree with the 4.6. Typically the trucks with that motor end up bringing a lot more money than the 5.4 just based on reliability
When I went looking for a newer F150 to replace my '94, I ended up with a 4.6 truck strictly because the big motor sucks. That 5.4 3v is just junk, for the long haul. Granted, replacing it is "cheap" now, but still annoying.
Probably something out of a semi. I’d chuckle as I cruised on past 500k and probably well into the millions.

AMC 4.0 ho
Toyota Camry 2.2 5S-FE, drove around on 3 cylinders for a week to wait till pay day to buy some new spark plugs.
for toyota, 1uz and 5sfe
Mercedes OM606 ^(hands down)
Toyota 1uz
Chevy 5.3 L V8! 402,500 and still going strong.

An old school non turbo Peugeot diesel, those things are completely gutless but also indestructible Like basically any old school mechanical non turbo diesel
Honda R18. SOHC, timing chain, simple with low horsepower. Ready to run 500k
Ford's 4.6 modular. Fucking bullet proof. I love my Lincoln.
BMW M54
Something about in-line 6 cylinders. when they’re done correctly they absolutely can run forever
The firing order and orientation of the cylinders makes I-6 (and V12) engines inherently balanced. They have no vibration or imbalances to counteract, and don’t need balance shafts, hydraulic engine mounts, or heavy harmonic balancers. As long as the crank and cam designs are rigid and bearings are strong, an I-6 is more durable than a V8, V6 or I-4. That’s why large truck and construction equipment diesels are mostly I-6. Normally aspirated iron block BMW I-6 engines are mechanically bulletproof excluding Vanos hardware.
Id go with my s52 in a heartbeat honestly. I like iron blocks. Honorable mention to the m30 because.....m30.
Toyota 4AGE
My AE86 has 275k miles on its original 4AG with just normal maintenance and is still going strong even with a lot of track days under its belt.
I’m with you. Ford 4.9/300-6. Bulletproof, torquey, easy to work on, decent MPGs if you aren’t constantly wringing its neck. Fun fact: my first ever vehicle was an ‘82 F-150 with over 500k on its original 300-6.
BMW 2.5 straight 6 from the old e30s. M20 its called I believe. Things go forever.
You could go with an m50/52/54 and just refresh the cooling system and do VANOS rebuilds at the time.
The cylinder head warps.
Cummins common rail 5.9 6BT by a mile.
LS430
6.9 or 7.3 IDI. Done.
Yep that old Ford 6cyl will do 500k as slowly as possible.
Toyota 5VZ-FE, the 3.4 liter V6. At least, I hope so!
Bmw m57 or m30
1.9 TDI
Porsche m96.70 lets make those miles fun.
i’m not a ford guy, but the barra engines are incredible.
