If you need repair than I can't recommend Pina Motorsports in Kent Wa more. Andre is the owner/Mechanic, and owns a 91 VR-4 himself. He may be a bit pricy, but if he fixes your car he does it right, and you can have great confidence that it will be solid there after.
Andre fixed all the issues I had gotten with working with Portland Speed Industry (PSI) - Stay away from that shop in Hillsboro, Or. (http://www.pinamotorsports.com/) Pina Motorsports
