Iv a r34 gtt series 1. I picked up a turbochargerbut not sure if its for the r34 gtt. Its a 45v1 with 3 stamped on the oustide and 2 stamped inside and has op6 stamped with 717b and a letter 4 also stamped on it.. the actuator is 29 0724A and Asn7. Any help on detils about this would be great. Could it be from a stagea?
