450 CC or 550CC

[F3600]

Hi, I just got my T28 turbo (wich is in nice shape) and i would like to know wich injector i should go with .. everywhere i look, everyone are always running 550cc injectors but some people are saying that 450 cc is good enough for 280 300 hp... My current goal is to be running maybe 260 something along those line ..

is the 450cc are borderline for this king of *power*

BTW, someone have some info of how to clock the turbo housing.. ? i see the fat C clip . Does i need to unbolt something else to get it moving?

thx

1) Use SEARCH for the injector question. The answer's going to be to go with the 550cc injectors but the why has been spelled out in great detail in previous posts.

2) Compressor housing (air) is held to the center by the big snap ring. The turbine housing (exhaust) is held to the center by four bolts. Without seeing the turbo I don't know if you'll need to clock one or both housings.

I'm surprised this post isn't locked yet.

450s would be totally maxed out at 280whp. Better off getting some 550s and running them at a lower duty cycle.

i didn't have to clock my T28 at all. i don't think you will need to either.

Use the 550's, and you shouldn't need to clock the T28. Please search before posting.
