WRX V3 Heads

Hi all,

Could someone tell me if the version 3 WRX heads are hydraulic or solids lifters?

Cheers
Chris

think they are both phase 1.5 design so it should be a straight swap

Head castings are the same but you will have trouble changing from Hydraulic tappets to the Sti Inner Shim buckets as the O/D of the buckets are different.

biggest problem is reshimming.. which is not bad.
