Nothing wrong with those twin scroll ebay turbos they are the same as gt pumps sells, the problem is the exhaust housing is too big 10cm2, gtps02t dyno sheet was not impressive either and that was on a 2.5, there is a thread on rexnet under gtpumps. I had a conversation with mark from gt pumps on the phone and he said they are designed for track work and high boost applications and on the road the transition to boost is very smooth. Better off sticking with p25 exhaust housing or pe1825 turbo, cant beat ball bearing turbos for spool or off on boost transition
