NHRA Trans Am

I have done a lot of research, and read the stickies, but i am still haveing trouble picking the right turbo. I have heard t70, but i think thats a little big i only want to run 4 or or 5 psi, and make 420 to 450 hp, I was wondering if a T04B with 60A/R compresser, and 1.15A/R exhaust, had enough flow, and if the exhaust A/R was too high and it would spool too slow? Basicly what is the smallest turbo i could run to make those kind of numbers?

Thanks!

Im gunna guess that both these turbo's are on ebay real cheap.

that To4b Probally has a t3 turbine wheel and is for some kind of diesel. The t70 is probally the "super t70" on ebay and is junk. These turbos will not get you to 450.

A new garrett 60-1 is around $700 to 800. a masterpower 60-1 or even a T61 maybe even a T66 is less than $ 600. any of them should net you 450 at 5psi

Thanks for the help and you are right i did see those turbos on ebay, and thought they were suspicously cheap. I'll look into the turbos that you said, but i am gonna have to make some more money!$$$

If I were you I would talk to Jose at Forced Inductions.com. He will give you a bunch of information about which turbo will work perfect for you situation.

I feel they also give good deals to LS1Tech members.

Good luck!
