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?

12:5 compression pistons are available from arias and CP. That would be my choice.

mahle also has 12.5:1 pistons(they come coated also), not sure if anyone has tried running over that yet

I got them and there the shit!

What is clearance like with these pistons? Have they been designed for full VCT advance?

 

[jtuner77]

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.....

 

[jtuner77]

this is true. I have Mahle's in my "street" motor and JE Fully Customs in my race motor.
