In the past ive seen some guys with B-series motors running around 12.7:1 CR on pump gas(and Hondata/Uberdata of course). With all the advancements in the K20A, how high do you think it can go on pump gas?
I truly can't answer that question till i put them in and check mechanically. I would say yes do to the valve pocket being cut as deep as the stock one, but I still would like to check.
mahle rocks, ive used them in 2 other motors(not k series) they are very nice.....they made the first alum. pistons ever!! cool shit. then again there are alot of good piston companies out there but everyone will always argue who is the best.....
I'm getting parts one at the time..NO motor yet already have the same exact piston as the previous post.I also have ef ready to have K swap.But no money for now
