I was thinking about upgrading the compressor whell in my greddy 15g to either an 18 or 20g wheel and port the housing. Would either of these be to big fo my z6. Im running uberdata, 3in exhaust 2.5in dp, and some other bolt-ons. thanks

is this upgraded absolutely needed? Are you just doing this for fun or is there a problem in existence?

UPGRADE, not REPAIR

More power is always needed. plus i thought it would be easier than peacing together a whole new kit.

I just figured a new wheel would be a high price.. can't you just up the boost?

your going to ---- up that turbo if you just bolt a wheel to it

The turbo is only efficient to 14psi, and even then its running out of breath. I found a company that will rebuild it and do all the needed stuff to convert it to either compressor wheel, plus the porting. It was pretty cheap also.

I thought you were going to do it yourself.

I wish, Im not the DIY yet still experimenting. But if he sent he a run down im always up to try new things .

changing a wheel on a turbo is one thing that you don't want to do yourself, unless of course you have the means of balancing it, which i don't think any of us do
