Sr20vet vvl head shimming - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm in the process of re-shimming my head before i start her up!!

I took down all the measurements with a feeler gauge on both the smaller lobes on the cams and this is what i came up with.

NOTHING could fit in between the cam lob on intake side rocker #4.

so now, i measure each shim, and order accordingly right?

Where do i order shims from?

Also what are the correct specs / measurements ?? i have Crower dual springs, with n1 cams.

just see what size you'll need and I can order it for you.

I directed him to Nick at 5523 motorsports. Mazworx would probably have a good idea of the shin height too.

Shingo at Bluemoon did my engine assembly and shimmed my p11 head.

Nick at 5523 was EXTREMELY helpful. I HIGHLY recommend him, he actually took the time to thoroughly explain the process and specs.

Crazy idea, but maybe you could post up the info so it helps other people.

Deezal · 07-02-2016, 04:05 PM

From memory when we did mine it was about 10-14 thou on the intake and 11-15thou on the exhaust with a rocker ratio of 1.6

I ordered harley davison shims as they were way cheaper, came in 0.05mm increments.

I assume your measurements were taken with your existing shims?

This is a great idea, but if you do so, please put it in the SR20 thread in chat.

Fuck I have done this a few times. It sucks when you had head work done, when I shimmed mine they were all over the place. I went to the Harley Davidson dealer and used the V-rod shims. You can also look buy a the hotcam shims to use.

IN : .17mm
EX: .37mm

IN : 0.08
EX : 0.12

Yellow4g63 · 07-22-2016, 01:48 PM
