if you guys are worried about 750rpm you don't want a single turbo https://www.nopistons.com/forums/pub...IR#>/smile.png

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

Yes it is a t3 flange. You can get a adapter to fit it on the t4 flange though from somewhere, don't know where though.

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

Yea, that's the type of thing I don't want to happen if I go single turbo..

How low in the rpms are you guys driving your cars?

Doesn't pull as well from 2k huh?

Maybe you guys need to pull out the 13B and drop in a 4 cyl diesel. Lots of torque from idle to 4k redline.

Seriously, if your just cruising then who cares how much power you have. If you want it to pull then you might want to consider dropping it a cog or two.

i dont always want to drop a gear or two like i do in my NA https://www.nopistons.com/forums/pub...closedeyes.gif

NA is more fun to beat on anyway, on the other hand anytime i want to

go slightly faster in the FD i just press the gas slightly and it MOVES

also fun, when i realyl want to go i downshift anyway.

2k rpms? well I guess I cant argue. I guess that means you want to lug around town just above idle? Who drives thier Sports car like that anyways? I'm not 70 years old driving a crown vic. My Dyno sheet was not even a well tuned speciman and it still makes as much power as the stock twins do down low. I added a high tension wastegate spring so now it spools faster down low. Even if it made slightly less power just above idle I dont think its an important factor to gauge the performance of the turbo. If you want alot of pull down low you need a V-8 with alot of torque. Rotaries dont put down that kind of torque. Even with stock twins they dont match the abilities of a Vette lugging around in high gear without any problems. Dont trade turbos. Trade cars. You wont ever get a rotary to perform like a V-8 down low.

i raced a vette, from low rpms we were side by side...i have stock twins

I have a vid somewhere of Nocab pulling me ~4 car lengths by the top of his 3rd gear. This is when I was running stock engine/turbos at 15psi and putting down over 380RWHP. He was running 15psi too. What a world of difference. Yes, he runs a GT-35/40 from Aspec.
