Hi guys, does anyone know anywhere that sells replacement bucket shims for the 2jz-gte pre vvti. I have just bought new cams and am 99% sure they will need shimming.

 

Easier for me to ask now so i can get them in asap

 

Thanks Andy

Toyota still sell them, but maybe someone has a bag of them sat on their shelf?

 

Cheers swampy, will get calcs done and post up what size shims i need and see if anyone has any. Failing that it will be toyota. Any idea how much they are each from toyota?

 

Cheers Andy

I would imagine a small fortune if purchased within the UK, take a look at Amayama. Just remember to add import duty, handling charges & VAT on top. To throw a wobbler your way, how about using the shimless buckets from the MR2 Spyder instead.

 

Also, do you have you got access to a decent online EPC?

I can imagine them being pricy too. I have thought about the shimless buckets. Do you just buy them in certain sizes?

 

And whats an EPC? [emoji23]

Cheers swampy. I thought they might so more specific sizes than that. After measuring the shims that are in with digital micrometers, some are coming back at such odd sizes compared to their size chart. I have some measuring up at 2.875mm and such like. They seem like in between sizes (1 thou increments) rather than 2 thou which they sell online. image

If I remember you've got a tolerance of 0.1mm to play with when checking the clearances

 

With stock cams yes. 0.1mm = 4 thou.

 

Stock exhaust is 10-14 thou

 

Stock intake 6-10 thou

 

However with these gsc s1 cams. It states that the tolerance is much closer and different to the stock cams.

 

Exhaust is 12 thou +- 1 thou

 

Intake is 10 thou +- 1 thou

 

So to get it bang on, 1 thou increments would be best. I will sort it either way by surface grinding the shims or shimming slightly on the slack side. Im thinking the freshly ground valves will move and bed in within the first 1000 miles so will be double checking them after that anyway
