This is a 95 supra NA motor with a turbo and were going to push about 12psi. The motor with this setup put out 315hp 275 tq at only 9psi. this should be fun:)
the 2jz with all the acc. shed off and a w58 trans weighs only 100lbs more than a fully dressed BP. Also i thought you all would want to know that this is not an expensive build due to the fact that i got the running motor for $100 and the trans clutch and fly wheel for $400. It is going to run a supra computer for the engine and the miata computer for the body. the shifter location is only and inch forward of the stock miata location but i think i can deal with that. This is all being done in a garage in the little old town of Mt. Airy MD with a bunch of 24 year old guys who have to much time on their hands if you have any more questions please feel free to ask. and if any one was wondering it should handle ok still and all i want to do is make 50 year old guys with their 03 corvettes and 20 year old girlfreinds cry everyday. Nice very cool you should start a Built Thread over here so we can drool over your project. Also maybe you could let us in your secret mounts set up, then we might see more 2jz miatas :giggle: +1 on the 50+ year-olds with 20 year-old gfs. I see them on a daily basis over here in Miami. It will be cool to deflate their egos Edit: post your engine in the for sale section with pictures |
Im curious how much room there is for the radiator, I wonder if youre gonna have to run the fans as pushers

the only cutting on the whole car is the little bit of core support you see in the front and a little trimming on the passenger side frame rail but not even enough to mess with the structure were talking like a 1/16 of an inch.

FWIW I easily fit a low-profile 16" pusher fan on my LS1 radiator, also on a NA body. The front of the radiator is pretty close to being in the stock position. I had to remove the hood latch to get the oil cooler in front of the radiator. An intercooler may be a tight squeeze if it is a big one. It might be easier to fit a big WI tank?
|
Holy shit that doesnt look bad at all O_O
|
the only problem i see that i have already come to terms with is that the motor dose stick out of the hood a lil bit but i have a freind that is a body guy that is going to trim the hood around the motor like a body dropped mini truck
|
Really nice work Sean.
I'd like to see how well the hood fits. (By your own post; you beat me to it). I may even follow your path in a few months. My local mechanic is rocking one of those motors in his own car right now and he's done a bunch of those for different local cars. I've heard him say those are bulletproof engines. Please keep us updated on your project. BTW; welcome aboard! |
I can't wait to see more pics and videos of this car!

It depends on your definition of good handling
With 300 extra pounds on the front wheels it would handle like total crap compared to stock, but probably still better than most cars, haha There are lots of 5.0 Miatas and they still handle very well. Plenty of on track video to back it up. That's with another 200 up front. If I didn't think that it would handle, I wouldn't be building one. |

Sean, you might want to look into using a Ford 7.5 or 8.8" rear. I just confirmed today that the Factory Five Racing axles with an 8.8" ford will end up being the same compressed lengths of the half shafts as a Miata. Diffs from a V8 Thunderbird are $100 and the axles are $110 each side from FFR. Here are my two diffs. I just put them together today for a comparison. Both come out to 53" where the big end stops and the splined part of the axle starts. The other big advantage is you don't have to worry about a PPF.

Little diff
and Rusty trombone diff That ford rear end looks heavy. |

If I didn't think that it would handle, I wouldn't be building it. More weight + Higher front spring rate (needed for said weight) + Stiffer front sway bar (to prevent roll from said weight) = More understeer and no, Im not just being an internet expert, I do have real road racing experience. Ive never road raced a miata, but the basic principles of chassis engineering are applicable to all cars. That being said, even with the negative effects on the handling, there is no reason why it couldnt be fast on the track, especially with all that power. It would just have more tendancy for corner entry understeer than a miata with a lighter engine in it. As much as people want to deny it, a lot of race cars are fast because they are powerful |
So sean, do you have to have a custom drive shaft made so that it will be the right length and connect to a miata diff and supra tranny?

300lbs extra pounds, slightly forward of the stock engines center of gravity is definitely going to have negative effects on the handling. Theres no denying that.

And all you have to do is add more rear spring and rear anti-sway bar to bring it back to neutral.
Im not trying to belittle the swap, like i said, there is no reason why it couldnt be fast on the track, but if I were building a dedicated track car I couldnt want to go this route. For a fast street car that still handles better than most cars I think its pretty great |
definitely in for updates on this one all of my friends have 2jz's and its pissing me off
