Which states that the 3rd Gen has a "shimless bucket"

Looking at the pictures here

http://www.rossmachineracing.com/3sbucket.html

Shows the difference between the 2nd gen 3SGTE bucket and the MRS bucket

My Buckets look like the MRS bucket but with a removable shim (on the underside) that I could change to alter the thickness without buying whole new buckets.... now the only trick is to source a "shim" from somewhere shouldn't be toooo hard.

Preguntas? Problemas? Comments?


I will append my own posting.....

also from the same toyota nation posting

Q: Whats shimless or shim under bucket lifters?
A: The stock bucket weighs 1.6 oz. & the MRS(MR Spyder) weighs 1.03 oz. That is a weight savings of 35.5%. When high lift cams are used with stock lifters it has caused the shims that are used for adjusting cam/lifter clearance to fly out. This eliminates that by eliminating the shim all together. That lightens the valvetrain weight and allows higher RPM limits.

I could have told you that... Same goes for the n/a 3SGE's also and the 16V 4AGE versus the 20V 4AGE. Almost all of the newer toyota engines... say 92-93 and up changed over to under bucket shims... then say around 2000+ they removed the shim completely... However this information is only useful if you plan on running some really knarly cams.
