I am looking to find the specs for a TURBO CHARGER to install on a 2.1L watercooled VW Transporter engine for a KR2 aircraft.

Yes i am flying with a 2.1L transporter engine its turbocharged at the moment but since I am now flying at sea level I am over boosting and running very high EGT.

Turbo people telling me the TURBO is to small need the specs for a succesful turbo charger installed on a 2.1L engine.

Please help
