have a 95 wrx wagon
changin block for a post 97 block (semi closed deck )
sti 3 standard pistons
rear thrust v5 crank ,think its of a v5 anyway not sure but i know its rt.
standard wrx heads but may change the cams to v3 ones but would need to change from hydraulic lash to the shims instead, all the same the lift is always 10mm the only thing that changes is the duration so.. i dont know if its worth it better low end torque but not to fussed about that?
forged h section rods
uprated main bearings and big end bearings and bolts
the bit im stuck on just now is the pistons ? i have a set of pistons that came of a version 3 that measure at 92.01 which is spot on but i do know that the standard wrx piston crown is completely different from the sti ones , obiously 1's forged and 1's not i know that just worrying about valve clearance as the valve pits in the crowns are deeper on the wrx piston than that of the sti but i suppose the compression ratios of both engines are completely different and is uppose the wrx heads and sti ones have the same 10mm lift the only thing that changes is the duration .

could some one back me up here and tell me fings are gona b alright with the pistons ?

sorry bout the confusing info
