Rb26 1 Piece Bucket And Shim.... Pros And Cons

[den001]

just wondering what revs the 2 piece bucket and shim are good for in a rb26....

will it throw shims at 9000rpm?????

i have hks 272 10.2 in ex

jun type b retainers

hks step 2 valve springs

bronze guides

was going to go the one piece kit but engine builder has advised me that the engine will be good for 9000rpm with the standard shims and buckets with his clearences...

Stock setup shouldn't be a problem at 9000rpm- I've heard stock valve guides are probably a better bet than after market ones too. You might want to look also at getting shims from a guy in melbourne i know, far better than nissan, they have .2mm case hardness and come in .02mm increments so you can rub them to your exact specs. Nissan shims are only .01mm case hardness and can't be rubbed down. Let me know if' you'd like the contact details (i think it's Precision Shims Australia based in melbourne but would have to double check), check with your engine builder- Oh and nissan shims are 18 bucks a pop (plus wait out of japan) and these are 8 ea and o'night delivery
