question about the GN tbo348 and an 8v

[finboy]

i'll supply you with a little info first...

"the gn turbo is bigger than any t3 made. its closeist cousin would be the to4b s trim. but it is a turbo made just for gm and is not avalible in the aftermarket, you cant even get a compressor map for it. the limitations of that compressor is about 375-400 hp. in your setup that exhaust turbine is too big. make a hybrid, find a t3 turbo with a .48 or .63 a/r and remove the entire compressor section. install your gn compressor and you ll have a fast spooling monster. I did. "


"this buick turbo has a .63 hot side, and i have been told the exhaust wheel is equivilant to a stage 2 t3."





the motor will be a 2.5/555 combo, mild ported g-head with back-cut valves, tbi header, downpipe and a muffler for exhaust, etc.

what do ya think.

this will give you an idea, the turbo i have is on the left...



my other option is use the intake housing and wheel and bolt it to a stock t2 exhaust/center sections.

but what worries me is will the engine start to choke on itself with the stock .48 exhaust side?
