I have just completed my home-made turbo setup on my Z6 (specs listed below). I will try to post some pics soon. I am still waiting for my 5g radiator to come in (it's smaller because my big crx one hits the turbo). The turbo is a T03 from a turbo sundance with 12,000 mi. .42 A/r. I am going to be running stock wastegate at 7psi daily. How long do you think it will last? The only fuel management I have is a V-AFC which I was told should work kinda well. The motor should hold right? I was told it will. The motor pretty much stock other than than a few bolt-ons. Just post your thoughts! I havn't driven it yet cuz of the radiator, but hopefully everything will be ok.
