To install pistons, in addition to the circlip pliers you need a good piston ring compressor and a piston pin installer. Luckily for us Summit sells a nice piston ring compressor for pistons in our size range. Piston pin installers just amount to a rod with an end that perfectly matches the ID of the piston pin so that it isn't wobbly and difficult to line the pins up with the holes but isn't tight so the pin doesn't get stuck on the tool. The ID of our piston pins is different from later model Subaru pins and from aftermarket piston pins. In my picture you will see the genuine Subaru Eg33 piston pin installer and one that I made being compared. The one I made fits both the stock EG33 pins and the high performance lighweight pins I used with my forged pistons.
