im building a motor, and people are telling me to do a 406, but i will be using a big turbo on the motor... can anyone tell me where i can find some 8.2/8.5 or so compression pistons. i dont have heads yet so when i buy some i can get 64cc or 76cc, so that part doesnt matter yet. i've looked in jegs and summit and all the pistons are relatively high compression... or atleast if your under boost.

 

you tried calling them? they can get more pistons than they list, they just usually list the ones they have in stock. I got mine from jegs, SRP forged, they'll be 8.7:1 when i change to 76 cc heads. but they aren't the right material for large blower, mine are 4032, so only for small turbo apps (coming soon! j/y turbo!) , but they can order the same pistons in 2618 alloy for higher compression/big boost apps.
