compressor housing questions: can I swap?

[andrave]

Hey guys I have my twins, and they are .48/.42 compressor/turbine. they are supposed to have a .60 compressor housing. Could I just unbolt the compressor housings and replace them with .60 ones? I don't know what turbos I ended up with. They have the specs of Z32 units but the flanges of skyline GTR ones.. I bought them as GTR ones but GTR turbos use .60 compressors, apparently. But mine have the GTR turbine flanges.

You SHOULD be able to as long as they both use the same CHRA. At least, thats my understanding for whats its worth

yeah thats what I was thinking... I just need to take a coupe sr20 guy's compressor housings then. They are .60, I think?

Make sure the compressor housing is made for the compressor wheel trims though. Too large and the clearance between the wheel and the housing will be too large. Too small and the housing will hit the wheel.
