Turbo too big?
I have been thinking about installing a blow through turbo set up on my '85 12a. I have an Air Research T4 turbo sitting around and was wondering if it was too big for the 12a motor. I don't have the carb or manifold yet but I'm sure you guys could point me in the right direction.

there are lot'z of turbo people in here. have you ever thought about a supercharger?
they put out a lot of low end Torque. I gave some turbo guys a ride in my car @ 7 stock and I think they might have liked it ...

Yeah, shutup kid.
I'd say it's just a bit too big for a stock 12a, it'll make a lot of power at high rpm, but you'll have no low end. It'd be perfect for a ported 12a though. I'd put it on there, but plan on porting your motor if you want the most out of it.
For a carb I'd use a weber 48dcoe.

Id first figure out how much rwhp youd like, then pic a compressor wheel that'll do it at a boost level your going to run. Once you figure that out( may take a minute) build an engine to spin it. Ive been playing with my setup for about 6months now, i think ive finally found what i like. I ended up with a T66, .70 compressor a/r and .81 turbine, running a Q trim exh wheel. Ive tried as small as a T04B S-3 trim and as large as a T72, the T04B spools great but just didnt have it in the higher gears. Next season i may go back to the T72 as the tuning gets closer. The guys on this forum will get you close, but in the end its what you like.
