RB26 Valve shims for a great price.

**FOOT** · 09-01-2011, 11:13 AM

I'm looking to make a custom shims that will suit aftermarket valvetrain. Oem nissan, Jun and Tomei Shims can be very expensive at $265 plus shipping and up a set. The problem is they are all 12mm O.D and the valve spring retainer I.D is bigger which gives you a risk of a shim splitting out from moving around. The reason why I'm making these is to avoid issues down the line and extras cost from engine builders. Having bigger cams and aftermarket buckets like tomei(4mm thick) and Supertech (3.78mm thick) can be a problem when you have a Camshaft of 30mm base circle versus 32mm which is stock. Your engine builder will still have to grind these like any other shims you buy as the thickness is 4mm. No one ever stocks new shims to begin with due to the cost and the fact there are so many sizes. Now I’m trying to find out how much will everything be with the machining and shipping within North America. The more people I have interested the cheaper it will be. I'd like to make this shim kit a max of $180 CAD shipped anywhere in Canada and the US.

I'd like to get between 5-10 people. Please PM me if you are interested.

Hard to tell from your post, are you selling sets of 24 shims sized to order
or sets of 24 shims that are exactly 4mm thick?

Basically you will have two sets. intake will be 3mm and exhaust will be 4mm. so the kit will consists of 12(3mm) and 12 (4mm) shims.your machinist still had to grind down the shims regardless if its oem. its very rare for all of them to have the same clearance your lucky if its 3 thats are the same specs.

I've ordered enough material for 10 sets. just have to wait for it to come in. then send it over the the machine shop.

Is the case hardening going to be through and through? If it's not, grinding is a no-no. If it is, I think I'll be in for a set. Want another 100hp with some big-ass Kelfords, and the lumpy idle (brap...brap...brap......makes me large).
