You build a new block first, right? If not, you would about 5 mins after starting it with two turbos pushing 22 psi....

22psi is 22psi. doesn't matter if its coming from 2 turbos or one. 2 turbos just run more CFM.

keep in mind 2 turbos is not necessarily better. Most big HP supras run 1 turbo. If you run 2 small turbos you may get good numbers. I imagine a low spool point and good top end due to increased CFM. but for big power. spooling 2 larger turbos will be just as hard as spooling a really big single turbo.

If you want a faster spool and good power amount of power form a turbo. I would get a single Garret GT turbo. The GT turbos have newest wheel technology and they have a dual ball bearing center section. They will spool about 300-500 RMPs soon then a journal bearing turbo.

What would be interesting to see if it could be accomodated would be to use a stock sized turbo for the first stage, and then a larger turbo for a second stage.

Also know as a bi-turbo setup, used on the S4's and some Mercedes/AMG cars. One turbo spools at low rpm and the other comes in later. twin turbo: both spool at the same time.

That's a fun fact. Take that home. Enjoy it.

As far as I know the twin turbo RX7s do the same thing, but you don't hear it being referred to as a bi-turbo setup.

built correctly, with a big turbo is 10 grand anyways. forced air is interesting but not used. gt35 is a proven turbo. its 4 cyls not eight and twin turbo technology is not at the home built level yet, to be worth the investment. good luck. one question... why. is it to say you have it or would it be to really use. two torbos sounds cool. a single turbo with supporting mods makes more sense...

Dont twin turbo the car for these reason:
1. A more liky chance you will break somthing
2. Need a new motor, a h4 wouldnt hold it dont think. so a H6 would be needed for saftey
3.New engine block(all the internals)
4. twin turbos are a money pit when u can get the same effect with 1 good turbo.
5. if you have money to buy 20-30k worth of Engine,turbo, ect, or parts then its a good idea.

Forced Air Tech?

Why do you guys tharsh and bash them so much? I'm just wondering. Has anybody on this site actually bought that setup and seen what it can do? Besides, the 600hp is on stock internals, ECM, fuel, pistons.
If someone (ME Planing on it as we speak, check out my thread in general aboot making a 200mph Sti, And a Ej25 to H6 swap in here).
If someone took out the motor, built it bullet proof, H4 or H6 and did the computer, fuel, exhaust ect to the nuts, that kit would rule all.

If you want to do something unique, save/spend the extra money on whatever you want, just make sure you do it right the first time for the right reasons.
