Usefull Conversion, lighter valve train assembly Options

MR2 Spyder Lightweight Lifter Conversion in 3SGTE

I found this out from a friend that did the same thing and was happy with the result Now I am going to do the same . Total cost of conversion is $220 (retail price from dealer) if checked and installed yourself. The Buckets cost $13.75/each from the dealer.

The stock bucket weighs 1.6 oz. & the MRS weighs 1.03 oz. That is a weight savings of 35.5%.

When high lift cams are used with stock(2nd gen) 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.

The MRS bucket eliminates the shim. You have to buy the bucket in different thicknesses to set your own clearances.

Hope you All like the info

PS Next week I start up for the frist time in about 2 years.

shimless bucket conversions have been around for a long time....
but to my knowledge high lift cams don't fit into a 2nd gen head....
