Yes I agree and appreciate your input mate. I was originally after a gtx 3582 and grant from proboost steered me towards the t04z. I'm honestly little concerned about it hence the questions. Now until I'm certain it will be a good turbo without to much lag I don't want to fabricate dump pipe ect to change it down the track. Car will be around 3200lb 3 speed 3.08 rear with prob maybe 3500 convertor. Bf2 motor e85.
