The turbo is as bought. It has never been blow and never rebuilt. The turbo hits boost at 2000rpm and full boost a bit over 4000rpm. Though it may seem laggy I had a std r32 intercooler, injectors, ecu and everything for that matter apart from turbo and exhaust. With a intercooler and ecu, I would expect the turbo to hit full boost in the 3rpm range.
