Me and my crazy ideas. I've already discussed it is possible to put a LS7 engine on the S30Z, so earlier after discussing about a LS7 engine on the S30Z, I'm thinking of putting a Toyota Tundra/Sequoia engine on a JZA80 Supra in the near future, but I'm not so sure it would sacrifice the handling of the car.

It may be possible and if it is possible, what are the pros and cons? Does it really sacrifice the handling? Can the heavily modified 3UR-FE powered JZA80 top the Lingenfelter modified LS7 powered S30Z? Is there something else I should know about this Toyota engine?

Answers and comments are appreciated. Thanks.
 
All I can say is:

Good luck with the wiring.

You'd have to check not just the weight, but the physical dimensions of the engine. I'm not so sure, but that engine might be a bit tall for the JZA80 engine bay.

Anything that you can physically shove into the engine bay should, theoretically, work, but you'll be paying through the nose for a relatively new engine, and even more for custom mounts, drive-shafts, wiring, and whatever else has to be moved around.

If you don't mind it looking like crud... anything will fit anywhere if you cut out the firewall (I've seen Supra sixes in 70's Sprinters). And if you don't want it to look like crud, you can spend a ton of money and/or time to get it right (check out the LS1 powered Civic Ci-vette).

But with a car like that... I'd probably settle for a turbo-six from a later Supra. You'll still have to wire it up, but it'll be a lot less complicated.

EDIT: D'oh... idiot me... that generation was already turbocharged... (silly me, don't know the chassis codes for these cars) just turbo the existing motor... As Supras are already capable of holding in excess of 600 ponies on the stock motor, you could spend a lot less than the cost of the engine swap and have a 9-second street car on your hands.

As for beating an LS1-powered Z... well... beat it at what? The Z is a lighter car, so with equal-powered lumps, it should theoretically be a better dragster... but a newer chassis car is usually stiffer, structurally, and would make a more predictable track car.
 
Personally, I'd look at that same LS7 swap. Or for that matter, any aluminum-block and head small-block be it Ford or Chevy.

Let's say in the Wangan line. I've been to Tokyo once, but not in the Wangan line. Starting from the Rainbow Bridge and ends at the Tsurumi Tsubasa Bridge. I'm not sure if you know the Shuto Expressway more than I do, but you can google some images about the Shuto Expressway. 0-400m isn't enough either.
 
well, Toyota V8 into Supra has been done before. in addition, V8, being more compact (shorter) than the original cast iron inline lump, it should fit in nicely. The engine is pretty wide, but so is the car. You might end up relocating various items such as battery though.. and as one of the previous posters said, custom parts will cost a lot.
 
If it's just for giggles and you can afford it, go ahead.

But if you're looking for bang-for-buck high speed power and a car capable of cracking 300 km/h, a turbo build might be a better option.
 
What is a 3UR-FE and what is a JZA80?

I thought I remember hearing that the engine in the new Tundras is junk, with camshaft problems left and right?

Also, does that engine even have much aftermarket support? Any tuning credentials? Keep in mind that since it's DOHC it is going to be very wide, very tall, and very heavy compared to the obligatory LS engine. It could possibly be shorter than the inline six, but you wouldn't be able to find out where it will mount until you start fabbing that up. Already this is sounding like a terrible idea unless you're simply considering it because it sounds cool. I seriously doubt how effective it'll be, especially since the inline six is so easily tunable and is already designed specifically to work in that chassis. The reason people put the LS engine in the Z and RX7 is because it's simply better for big power than the engines they already have. But I don't believe that's the case with a later model turbo Supra.
 
4.7L 2UZ from a 2003 Tundra . Twin turbos have been added. This same guy is building a 5.4L stroker from the same block that's going into another Supra.

It sounds like Bench Racing to me.

Had I the money, I might try and see if I could nick a Sprint Cup, Busch, or Craftsman Truck engine, but big Toyota V8 Supra is a neat idea.
 
I don't see whats wrong with the 1000+hp capable Supra engine in the first place.


Is it a just a shell that needs an engine, or are you throwing out the stock engine in an epic waste of time and money to be different?

NOTHING beats displacement. There are quite a few Supra owners with deep pockets, and simply put, 3.4 (as big as a 2JZ can get) is just not enough to keep up with the cars coming out nowadays. Rather than deem the car outdated, why not give a powertrain update a shot? Plus, as you might expect, there is much more mid-range and low-end torque to be picked up this way. As far as weight distribution, we'll just have to see if this car ever gets weighed in, but 4 cylinders long compared to 6 cylinders long might help more than the extra weight hurts. We'll just wait and see (if one ever gets corner weighed).

It's a great chassis with a good motor. Why not give it a great one? Unfortunately, this build is sort of an ultimate street/show car, and he has no intentions of pushing the motor to its limits. However, the 5.4L that I mentioned earlier is going into a more extreme build (with a 6sp, unlike the TH400 in this one) that may just unleash the potential of the truck's cast iron V8.

For what it's worth, lots of LS1 guys swap out for the truck LS1 blocks that are only differentiated by being iron, and they have since boosted the crap out of them for some spectacular results. Being a huge Toyota fan, I can honestly say I'd rather build an LSx Supra than try to keep it in the family with a Toyota V8, but I'm anxious to see these swaps getting more popular either way.

Also noteworthy, I know of a MKIV Supra with a big block Chevy and a massive turbo that's put down more at the wheels than a 2JZ will EVER see at the crank.
 
BBC is over twice the displacement of a JZ bored and stroked as far as it can be.

7.4L by default, 8.1 easily within reach.

I'd like to see a Supra with a Ford 4.6L Cobra motor in it. Preferably the 2003-04 complete shortblock with 1996-8 Cobra heads and higher compression.
 
Oops, my bad, it's a small block Chevy. 6.2L, 106MM turbo. Built to boost.

Anyways, sorry if it seems to have gotten off-topic, but my point was that Toyota makes great V8s, but far from the best in terms of performance cars. Not to mention the lack of aftermarket support for Tundra motors is going to make it a much more expensive swap than a tried-and-true Chevy motor. The guy building the TT 2UZ admits that the Toyota badge is pretty much the only reason he went with the 2UZ over an LSx or something similar.
 
Well, if you had very deep pockets you could play with the 2UR-GSE, but meh, too much time, money... And I sure as hell know I wouldn't want to deal with the wiring.

A personal note:

I'm not a fan of folks shoehorning small-block Chevy V8s (despite my love for them) in anything Japanese. It just seems awkward, and truthfully, a bit taboo. It seems like a modest displacement V6 out of one of the newer Toyotas would work fine, as my understanding is, they're very willing to accept forced induction. But, alas, its all a lot of money to be playing around with.
 
It's fair that you cannot do it alone. At least if you have a friend who knows a tune shop that can help you with, it can save your precious time, but you and the tune shop have to pay the parts that send out from the factory. Am I right on that one? I'm not so sure because sometimes you have to pay the shop too.

I think Toyota made great V8s, but there is a V12 Supra that came from Top Secret. It came out from the Toyota Century limousine and that's the only V12 engine they got from Toyota. Otherwise, a V12 is a waste. Sure it can fit, but instead a V12 Top Secret Supra can already beat a 7.0L LS7 Corvette with the upgrades from Lingenfelter.

It has to be the Toyota V8, so it can be challenging against the Chevy V8.

As for Keef,

The 3UR-FE is a 5.7L Toyota engine designed for the Toyota trucks and the JZA80 is the chassis code for the 4th gen Toyota Supra.
 
Funny... isn't it? That thanks to "drifting", there's a trend of mad-scientist tuners swapping out the perfectly serviceable 3.5 liter V6s in 350Zs and whatnot, and replacing it with a measly 2 liter engine... just for the better weight balance.

While some nutty Supra guy, on the other hand... is going the other way... :D :D :D

Like I said: Nick one of those. Granted, not made for boost, but 800HP easy...Running Methanol, even more...
 
I looked around on TRD's website...I'm not exactly sure WHERE you can get the NASCAR spec mill, but I did find where they have the Sprint Car mill. You might E-mail around to some USAC or NASCAR teams, see where they got it and how you might be able to get ahold of one. Might make the car track-only, though.

EDIT: They say that Ed Pink Racing has the USAC-spec engines, which are leftovers from the OLD Craftsman Truck design.

NASCAR engines ran on high-octane leaded gasoline. As a matter of fact, 2008 is the first season they have ever used unleaded gasoline. Damn the EPA!

It's a race car engine, which is race car light weight, race car powerful, has race car tight tolerances and race car compression and race car nuts and bolts. It's also got the life span of a race car engine because it's a race car engine. So unless you want to be buying new $50,000+ race car engines every year then that would be one of the most ridiculous ideas I've ever heard.

Let's see you run your engine hard for hours upon hours. I think at normal, street driving rpms, this engine could outlast a normal engine except for possible heating issues.
 
I sent an email to the Joe Gibbs Racing webmaster about finding to purchase the TRD Camry V8 5.9L engine just a few moments ago and gladly, Kyle Busch is in that team as well. I bet he will know where to purchase one, so in the future, I won't be getting the 3UR-FE after all.
 
I did just think of a possible problem, though...Street-legality. I mean I know Toyota's used the engines in the past for SEMA rods, but even then...
 
Why wouldn't they be legal? Do some states have weirdo laws about engine swaps?
 
I was thinking that it would be a race engine in a street car...but, then again, It's a one-off, and I DO remember a story in Motor trend about a guy who made a 410 Sprint to be street legal. I'm thinking of sniff tests and other emissions things.
