hey guys thought i’d ask this, cause i got no response from anyone from “clubsi.com”:evil: Anyways i’m coming up on 260,000 miles and its time for a rebuild. I’m going to raise static compression and i wanna know if anyone has put in b16 or gsr or itr or ctr pistons in their b18a. Just wanna know if any clearance problems between valves and pistons.
i have type r pistons in my b18a - the only thing you have to do is shave 1mm off the wristpins in order for them to fit correctly. the compression test i did showed b/t 10.8/10.9:1 - anything that high though, it is necessary IMO to use 92 or higher octane fuel. if you’re not now, it’s just a little more expense every time you fill up but i think it was worth it
