traded several pm with blackjack today and forged pistons are not needed but he said if im rebuilding put them in. he knows his s#@t. the tranny is the issue he said needs to be upgraded for turbo with 10 + psi of boost. stock set up is good for up to 8 but any more stuff is going to start to go south. i would like to get a new motor and rebuid it and invite everyone to the track to see how much nos a stock gls can take
