Hi guys
Just test fitted some Tomei Poncams into my R34 GTT. In the sheet that Tomei supplys it states that I need a 0.45mm clearance between the bottom of the cam, I cant think of the name of the part I'm looking at, and the buckets. Right now I have a 0.30 clearance on the Intake and a 0.33 clearance on the exhaust side. You can see the specs here
My question is, how do I increase the clearance from .30 and .33 to .45. Do I need new buckets or the old ones re-shimmed, as I've been told?
Any help would be great. Thanks
edit: forgot to add they are 260 degree 9.15mm lift type
