Re: changing compressor housing (wantboost)
oh...i just wanna know if i can still replace it with a smaller compressor housing...right now the housing is 57 trim on the cold and .63 a/r on the hot side. i wanna replace the 57 trim for maybe something smaller. its a t3/t4 master power turbo.

Re: changing compressor housing (ek4__)
i dont think it's that easy......the housings are machined to fit that turbo/compressor wheel.
you should contact master power and see if they have a smaller housing avalible....

Re: changing compressor housing (ek4__)
57 trim is the wheel, not the ar of the housing.
youd need to find a housing that is machined for your wheel
and removing it isnt hard, just take the bolts off of the backplate and it should just come right off

Re: changing compressor housing (ek4__)
No, it should'nt be hard at all to remove the housing. You are mixed up. You have a 57trim wheel, not a housing. I'm quite sure that you can only switch to a different a/r housing if it is machined for your specific wheel. For example, I have a 40 trim t04e wheel in a .50 housing. I could switch up to a .60 housing only if it is machined for the 40 trim E.
You probably have the .60 a/r housing(though i'm not familiar with m/p). I know they make the .50 for the smaller wheels, but i'm not sure if they have one for the 57 trim. Also, a smaller a/r housing might come with a smaller inlet. Mine is 2.75", but some(if not all) of the .60 housings come with a 3" inlet.
Why are you set on a smaller comp housing anyway? If you're looking for a quicker spool, you will be disappointed. What changing the comp housing does is alter where the efficiency range is located. If you have a certain wheel, and you think that at your boost level and peak hp rpm's you are slightly out of the turbo's optimal efficiency range, switching to a smaller comp housing will move the efficiency island slightly to the left on a compressor map and vice-versa. You may experience quicker spool, but I doubt it would be significant enough to warrant the trouble. If spool is your goal, then concentrate on the turbine side.
