crank rod turbo piston combination.. need help b18c5
I have a b18c5
i plan on boosting it and i want to know what my compression would be if i used an LS crank and LS rods and turbo 9:1 compression pistons for a b18c5... would i still have compression of 9:1 or would it be higher? the bore would be stock 81mm if the compression is different can someone give me a formula or help me out and tell me what piston i need for 9:1 thanks

Re: (TURBO-WAWA)
Yes the rods will fit as long as you use the LS Crank and LS pistons you wont be able to use your hype R pistons due to the location of the wrist pins. The compression would be around 9:1. The only thing you are changing is the stroke not the compression.

why not just put forged pistons and eagle or pauter rods in it and leave you type-r crank in and just get that micropolished and balanced?

Okay... yes LS crank and rods fit in a c5... and im not using stock LS rods... i would be going with LS eagle H rods (they arent weak)
and im not saying i would use the type r pistons... what i want to do is boost it with this setup but i dont know where i can get LS low compression pistons... i cant find anyone that sells them for an LS crank and rod set.. all i can find are B18c low compression pistons, so what i want to know is if they will work or do i need to keep looking for LS low compression pistons? and i would have used the type r crank but its way out of spec. and cannot be turned
