What would I need to do to put ITR pistons into my b20? My new to this stuff so bare with me.
B20 Bore = 84mm
B16/LS/GSR/ITR bore = 81mm
I don't think they make 84mm overbore ITR pistons
lol,. they don't...........
get some 84mm pistons mang.
they will fit.. you might have a little piston ring gap issue, and possibly a low compression psi, but otherwise it sounds like a great idea.
tell me you kidding?
81mm ITR pistons will NOT work in a B20.
the itr pistons will be rattling around in the b20 cylinder. you wont even have a seal.
The motor wont start i put some itr pistons in a ls block that was 83mm and the pistons was stock size 81 just to see if it was posible ..and the mortor never did start.....but i did here the pistons slaping around on crank over....that was cool
yes, i am kidding. a 1.5mm piston gap and 0 compression might be a "little low"
Just use JB weld to make some extra extra thick rings.
Jb Weld fixes everything.
call up je, they got slugs for b20 that bumps comp up to 11.5. thatÂ´s basically your only "type r piston" right thur.
in a B20A(old prelude) they will fit but not in a B20B or B20Z(new CRV) or in a B21A1(old prelude si).
