Hy all,

Convers with all of you on this forum is new for me, so i hope i will ask the good question.

I just want to know the aproximate compression ratio i have with this setup:

Stock B18C1 Bottom with type R pistons and rods
3 mm Cometic head gasket
and B16 Head.

I dont have a compressiometer, but i think i'm closer to 9.5 or 9.0 to 1.

Every answers will be appreciate.
Thanks all. :( :)

IMO, you are about 9.8-10.2. Just a wild guess.
 
Somewhere in the low 9 range, depending on if you have USDM ITR pistons, or JDM.
 
IMO, using c-speed's site and USDM ITR pistons its at 10.1:1...
 
Did you adjust for the head gasket? Using theirs I got around 10.1 till I change the HG to 3mm.

The pistons is USDM. what year is, i don't know.
Sure that, in N/A i will be closer to 10:1 (maybe a little bit more).
But, i want to run force induction, that's why i swapped the head (B16A: bigger combustion chamber) and put a 3 mm cometic headgasket.

I think i will try to buy a compressiometer and do the test myself.
Maybe it's the best way to go.
Thanks everybody FOR YOUR HELP. :) :)
