i have a 2.5 semi closed block from a '04 - '06 USDM Sti and has done around 30,000
the thing is i will be getting a new crank with acl bearings and will also be getting forged pistons and rods ect.. but should i get over size pistons or drop in ones ?? as the bores look fine and still have cross hatching down them and have very little wear any help or advice would be great
