If you go with the gt35/40 or even a t62 (.70 compressor & 1.0 hot side) like me, you will be asking yourself "what turbo lag?".

What's the difference's between the GT35/40 and your T-62? I'm guessing the T-62 will put down more power..

Well I don't know all the specific details of both to give a good comparison. Both about the same size, the t62 may be a bit larger physically. The main difference is i'm non-bb which would allow the gt35/40 to spool quicker. I see 5psi @ 2700rpms, 10psi @ 3400rpms, 12psi @ 3700rpms and 15.5psi @ 4020rpms according to my datalog. A single turbo makes good enough power at 5psi to lag from light to light comforatably. I'd say normal cruising speed is 2500rpms, down shift once, hit the gas and your into 15psi quickly.

Ok, cool. I'd probably go with the GT35/40 since it's BB. I think the quicker the spooling, the better..

Yeah, I went the cheaper route, otherwise the gt35/40 would be on my car. Its an easy 500rpms quicker spooling than my turbo. So, it can't be too far from stock.

The GT35/40 is far better then a T78..I'm not going into a long discussion as I think it has been beaten to death here on this thread. The GT35/40 produces power much quicker then stock twins, t78, etc. It can hit 15psi 750RPM quicker then most others on the market. There is a newer version called the GT70R, but until it's price comes down we're not gonna make kits for it unless the buyer is willing. The only real difference on the GT70R is the compressor wheel has a more agressive cut and looks mean as hell...so far in simple testing it may even spool 200RPM quicker then the GT35/40...we'll see...

Is the GT35/40 really a T3 turbine flange rather than the T4? My exhaust manifold is T4.

RotaryMan88 - Can you PM me pricing on the GT70R?

...What about T04-R vs GT-35/40? These are what i've been looking at, short of the Border twins. https://www.nopistons.com/forums/pub...R#>/tongue.png

https://www.nopistons.com/forums/pub...withstupid.gif Yea, how much is this GT70R?

kahren 05-23-2003 06:56 PM

i have been in a couple gt35/40 cars and they are nowhere close to the stock twins, go take you rcar for a drive

leave it in 3rd gear at 2k rpm and try to accelerate without downshifting, now go drive a stock car.

and dont tell me the diffrence is minor https://www.nopistons.com/forums/pub...R#>/tongue.png
