hey guys... well im trying to find some stuff to do to my
heads that i just got and one of them is looking for a shimless
bucket...

has anyone experimented with using shimless buckets in there
DOHC heads? anything from another auto make that might work?

just putting this out there to see what comes up

cheers

Yeah....try 04 USDM STi buckets. Measure the total thickness of your shim/bucket assembly, and order the appropriate shimless bucket. They're about $15-20 each and you need 16 total.

im pretty sure they were a different diamiter last time i looked... i'll take another look for sure, but im almost 100% positive... i know in the wrx heads they fit awesome, but not in the 2.5 dohc heads.

Depends on the year, I think...... 98-99 EJ25D's should be a direct fit with an 04 EJ257 head. 96 EJ25D had different buckets (and hla's) so they won't work for sure.

What happens when you need adjustment... if you go shimless?

 

[marc l]

the shimless buckets are all different sizes so u would buy new buckets...

but i hope you'd never have too :S

that would be a pain in the ass!

all the adjustment is done prior to the head going on

the motor in my case

^^^ Yup. There is no adjustment to make. If the lash isn't right, you buy a bucket with the thickness to make it right. However....you can slightly grind down the little tit inside, to mae it a bit thinner. I don't recommend it unless you're sure you can keep it nice and flat. Also, I've read that the buckets are only case hardened....so too much grinding can take the hardness away, leaving you with a bucket that will wear out.
