Im begining to gather parts to build up another block. Of course, when it's finished, I'm going to want to test the thing. My question is; is it a good idea to build the block with stock compression and boost it or would it be better to just drop in some lower compression pistions. I dont want to be driving aound with lower compression so when the block is complete it's just going to be sitting in my garage, shed, living room... whatever; until i have my turbo system ready to go. More insentive to boost sooner I guess. The big problem will be, I wont know if it will work until I install it, and im sure as hell not going to slam it in, start it, and swap it back out. I would also like to be done with the break-in time before I boost so i dont get excited and ruin it. Thanks for the help, I really appreciate it.
Also, how much would it suck crusing around for a while with lower compression? Can it be compared to anything ie. stock, no CAI, whatever? Thanks again.



"Shut your mouth and open your eyes."

4% total loss of power by going down 1 point of compression. Not that big of a deal. It would be like driving a stock NT (if you have intake, exhaust, udp)

I don't think they make stock compression pistons in forged form. Just go lower.

just need custom pistons extra 100$ takes je 10working days to build customs usually

others could take upto 6weeks to build customs.


stock compression wouldn't be a bad decision just cant run as much boost on pump gas youd be limited somewhere between 13-18psi depending on your tuning abilities.
