Hi everyone, i have to bore and hone my block and i want to have higher cr than 8.4 or 9. I want a cr between 10-10.5 and i've done somme research and we don't have many choice for h-serie. So I look to another possibility put wiseco k20 piston with 5cc or 8cc dome that put me exactly were i want.
I know that some had do this with n/a motor but I find nothing in F/I. So I want to know if it's risky to do this? If the piston is weaker that a dish one?(I ask because stock k20 are at 11 and some put very high whp numbers)
I know that the valve angle is different by 2 or 3 deg but i also know that the combustion chamber is larger in my head and the k piston are 1mm shorter!!

PS: For those will said to put dish piston I already do it with the wiseco 8.4 and I really hate this? This engine will run s2p1 with 6266 t3.82

k series pistons are used in f and h series motors without issue.

So there is no mod to do with aftermarket piston? And about the strenght?

you need forged rods... and if your h22 has frm sleeves then you're screwed. you would need to resleeve the block to run forged pistons.

the only forger pistons that work with the frm sleeves are made by Mahle

they aren't any different from any other forged piston so there isn't a strength difference
