This is the newest forged piston out on the market that we have designed in conjunction with CP Pistons. This is a true 9.5:1 piston. Once compression is calculated this piston puts the engine at 9.2:1 compression PERFECT for boosted applications. GTP inspired to bring you the absolute best in performance, these pistons model the early style pistons that were used exclusively in the GTP series back in the late 80’s and early 90’s GTP SOHC engines. A blend of the old school with the new school these pistons feature attributes from a SOHC cylinder head profile (2 valve) and coupled with a DOHC lower half design features based off the DETT model engines. Z31 owners get the best of both worlds!
