That made me start trawling back through my receipts. I bought an actuator about a year ago from Motorsport Developments during the time I was getting the head done as I was advised my old one was not moving freely. I foolishly bought a -34 Garrett, where I think I should have ordered a -31. I've only realised this as I have just started driving it again. Now do I put a -31 on, or can I keep the -34 and make an adjustment to suit the turbo? The car is totally standard, 4x4 91 Red engine. What are my options?
