2jz-gte vs 2jz-ge. Please i need some help!

[Alex_me]

Well i always dreamed to have a MKIV Supra and now it's time to buy one. I'm looking for a Supra as close as possible to stock so i can modd it from scratch it will finally be a single turbo one. My question is what should i buy a non turbo one w/ 2jz-ge in it, it's cheaper because it has no turbos anyway i would of changed them or look for a TT Supra w/ 2jz-gte. What role does 2jz-ge and 2jz-gte play when you mod your Supra is there any diffrence in modding them, they are both as strong, have a specific sound or they play the same when you single them?thks

What are your power goals? Budget? And intended use?

[Alex_me]

My power goal would be around 700rwhp and i have the budget for that. This Supra will be my daily car. I will use it on trips, around town and of course for racing other fast cars and my friends cars
So it's worthed the extra money on a TT Supra considering i'm going to single it?

The idea of going with a non-turbo may sound appealing at first, but in the end I think it will probably be more trouble than it's worth. Even if you're going to ditch the sequential turbos, you still have the plumbing, piping, and ECU changeout to sort though. (Someone feel free to jump in if I'm incorrect about the ECU issue. The non- turbo ECU can't support a turbo motor, can it?)

Were you planning to try and run 700hp on stock internals? If you plan to drive this car on the streets regularly, you are pushing the reliability limits of the turbo motor. I seriously doubt the non-turbo could be pushed anywhere near this limit due to internal differences, the most significant of which includes a higher compression ratio. Also keep in mind that a non-turbo model sports a five speed manual; only turbo models received the six speed.

Speaking of transmissions, are you planning to go with an automatic transmission or a manual? The auto Supra is very solid, and my research has found that you can now buy nice turbo automatics for somewhat reasonable prices (mid twenties), which is not a ton more than a nicely kept manual non-turbo.

Long story short: Unless you really plan on tearing into this thing and going far beyond bolt on components, you are probably better off starting with the turbo.

Then again, if you planning on building the bottom end of what you buy, the Supra lose some of its appeal. The main appeal of the Supra is its bullet proof internals, but if you plan on providing your own internal reinforcements, 300ZXs, 3000gts, and RX7s suddenly come to view as having nearly as much potential as the Supra.

If the Supra just does it for you, though, go for it. There's not a thing wrong with spending money on the car that you really like.

Thanks for the answer. Reading your comment i decided that a TT Supra will suit my needs best and i won't risk buying a non turbo. BTW i'm going for manual what single turbo kit would you reccomend for a 700rwhp goal? i was thinking about a T76 got any suggestions?
thks

700 HP is not a "kit" job. You will have to take the car to a shop and have a custom build done, to include rebuilding the motor with new internals to support the power. It will also require some sort of fuel management with a good deal of dyno time to dial the motor in. This is not a bolt on job that can be done in your garage. At those power levels it will not make a good DD. Reliability and drivability will be issues. So, just what is your budget?

This guy is speaking absolute truth. I've driven a single turbo Supra that dyno'd 497hp at the wheels, and it was a real handful. Lag was bad, and when it started spooling, it spooled HARD. I drove on some pretty curvy roads with it, and it was no fun. I'd brake hard into the corner, start getting on the gas as I was turning into the apexes, and the turbo still wasn't spooling by time I came out of each corner's exit. Once it did come on, I wasn't really concentrating on charging into the next corner as much as I was just flailing at the wheel in order to keep the tail end behind me. I can only imagine what 700hp would be like in a street driven car.

I also didn't notice that you stated 700 WHEEL horsepower. What would that be at the crank? Somewhere in the 800-900 hp range? A stock bottom end MIGHT put up with 700 at the crank with appropriate fuel, cooling, and probably some alcohol injection, but I really don't think 800 on a daily driven car is going to happen. I've heard of some owners claiming outrageous numbers on stock bottom ends, but their cars spend most of the time sitting in shows and making an occasional dyno pull. If you really plan on driving this car, you've gotta build the bottom end. Also, while the IDEA of having a 700hp street car sound awesome, I wonder if you'll really like the reality of it. Such cars often end up being an exercise in frustration.

Personally, I'd shoot for maybe 500 at the crank, or perhaps 600 max with an alternate tune to put me in a very streetable, low boost mode. I'd also concentrate on getting the head set up to move great CFMs at lower RPMs so you don't have to rely so much on big psi and high revs to make power.

One more thing... Considering the amount of money you would spend on this, and since you want a street car, are you SURE you don't want to consider a very nice used Porsche 911, NSX, or even a Viper?

Sorry for the long post... just some of my thoughts on a topic that I myself have been pondering for a long time.

I will spend as much as it takes to make it 700rwhp.

Thks again for another consistent answer. A Supras bottom end can hold over 1000 hp from what i know. 700rwhp daily driven Supra is nothing surprinsing ...Marko's Supra was dynoed at 1520rwhp that's 1900 crank hp and it was his daily driven car!and examples could go on. My car won't be at any momment on high boost for daily driving i will of course use low boost and add some hp only when it's nedeed. Neither of the cars you mentioned don't tent me at all i like something diffrent and i can't say i love supercars...Honda NSX...that's a bit expensive and only 280 hp...i don't think it's a good deal. And more than that i was dreaming of having my Supra for years and i can't spoil this momment.thks
