I ditched the mbc and got a 15psi actuator and sent the turbo to Deadbolt for their monster port service. I opted not to go with a bigger compressor wheel because I want as little lag as possible, you know first hand what the 1.6 power is without boost. I want this to be a boosting little *****.
DEADBOLT MONSTER PORT SERVICE
Better response, quicker spoolup, reduced boost creep, better "roll-on" acceleration, and quicker torque peak. Unlike most other porting services which simply smooth out the dimples and casting marks in the piece they are working on our system is different. We port match the exhaust housing to the downpipe gasket, resculpt the inside of the exhaust housing heavily, oversize the wastegate to help prevent boost creep, then smooth the area where the exhaust gasses enter the exhaust housing.
