    A while ago someone told me that a good way to get 11:1 compression on my 96 ls motor was to use JDM b16a pistons. But, what year will I need them out of? Anything else I should know? Let me know, thanx.

    go with CTR pistons, you'll be much happier. CTR's in an LS make great power.

    What kind of compression will I get with the ctr's? Also, what year of ctr's and what all will I need with them? Let me know.

    if you do CTR's you'll be around 12.5:1 CR, what gas do you plan on running on, what kind of tuning?
    i suggest sticking with JDM b16 pistons, anything from 92+ (i think that is the years of the SIRII) will work.

    Actually you can use any generation of B16A (SIR) pistons. Im using SiR1 Pistons in my LS. Good luck.

    I didnt say they were the same, I simply said any B16 piston will work in an LS block.

    They yield different CR's though. They'll both work, but SiR I's will be about .2 lower than SiR II's.
