I have a Godspeed kit. But they're all the same junk. If you are absolutely set on an eBay turbo- before you install it, take it to a turbo shop and have them check clearances and balance it for you. It might prolong it's life. My Godspeed turbo has under 5k on it and i'm so very unsatisfied with it. Makes power, spools fine.. leaks oil and makes noise.
Time? Yes. Money? Yes. Worth it all? No.
Starting a new build for more power next year though, so it's not all that big of a concern. I'm in the process of trying to buy a house from a friend's grandparents right now. Less then ten miles from my shop- and it has a two car garage.
In two months i'm building a turbo CRX for a friend, so I will probably make a build thread for it. (However it will move a lot faster then this build did.)
I will probably also have a build thread for the 600hp third gen.
