I've got a garrett 60-1 hifi right now thats been damaged and am thinking of replacing it with a T04b. The turbo i'm considering is has a .60 a/r compressor housing 54mm trim with a 1.15 hotside.



My 60-1 hifi was a .55 a/r compressor P trim with a 1.32 hotside. I'm trying to limit my power output, i'm afraid of cracking my rear plate (i've got an S4), but I also want to make sure I'm going to have decent power with my half bridge port.



Any input that will help with my decision would be great.



Thanks, Chris

I'd go with something at least 60mm

What do you mean by too small? When I hear someone say that I think: small = choking on too small of an exhaust side.



As far as too small of a compressor wheel, its not too small.

to small as in, it going to get me near my 500hp goal or it only going to put me in the 350-400hp range?

Are those flywheel or rwhp?

flywheel

i plan on putting 400rwhp at like 14psi on a t04b with those exact specs. someone on rx7club with almost my same exact setup did 404rwhp at 14-15psi on a t04b. hope that helps.





ps thanks by the way, i couldnt remember what specs my turbo was...friggen ebay.

I wouldn't try for 500hp on a B on a E you could get 500 flywheel hp tho.

if it looks bigger then stock then it is fine

you're trying to limit your hp to 500hp at the flywheel?
