I have a set of 135i turbos that were upgraded by TurboLab of America with a larger Billet Compressor Wheels and a 9-Blade Turbine Wheels. They also have the upgarded Wastegate Rattle Fix. They were installed and ran briefly on my car but when on stage 2 MHD my clutch slipped dramatically. I just took the car down for a Spec Stage 3+ install and found oil pan gasket is leaking into the Bell housing. These turbos only saw 18psi only 2-3 times honestly. They are still in new condition. I can take pics of them as they are still currently installed and will removed once sold. Price is fair and firm with no core charge or wait. $1000 shipped.
