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?

pretty much yea, it seems that if you go much over that the casting on the rear plate will break

hey does anyone know anything about the TA series turbos???

500hp, Ebay, cracked S4 rear plate.......Something does'nt mesh there. Your requirements and your capabilities just don't mesh. https://www.nopistons.com/forums/pub...IR#>/blink.png

I didn't say anything about ebay? I'm just trying to find out what horse power range that T04b is going to put me in. I'm aiming for around 450-500 flywheel hp, I'm trying to see if this turbo is going to get me anywhere close. I mention the rear plate thing because the S4's have weak rear intermediate housings and tend to break when you get upwards of 500hp, or at least that has been my experince.

Just allow the t04b to ingest some Enzyte. Maybe that will help some???

and i thought it was the rear plate that cracked on s4s maybe you just got confused for a second?
