ive been doing some reading been trying to switch things up a bit ive noticed how most of the ppl on this forum always try to be kno it alls with out knowing much lol but have you guys heard of a set up like this or even having B20 pistons on Ls block... what would the compression be and how would it do with turbo??

 

If you bore out the LS block, you will probably be able to use B20 pistons, but you are better off just buying a B20 to start with since that is the main difference between the B20 and Ls block.

Never heard of H22 pistons in a LS. Sounds like a lot of work for minimal gains.

 

yea ive read in other forums about boring out ls block and replacing the psitons with b20 ones but i was woundering since the ratio will change and the compression on h22 piston would be better then the b20 pistons ....... but b20 blocks go out quick ive had a friend go tru two blocks after runing the car acouple times ive ran ls turbo at first ls heads suck!! lol so made it lsv and block still strong and healty... and guessing how would it go about in compression diffrence between both h22 and b20?

 

I am not even sure you can bore a LS block to fit h22 pistons. I wish i could be of more help.

Sounds like the All motor section on honda-tech would fare well for you.
