k20a2 pistons

[Hoff Daddy]

I was quite interested when I saw I could potentially get 14.1 compression out of k20a2 pistons. With a stock size lightweight aftermarket rods and crank, good valve springs in an h22 head, and maybe a cam I could get plenty of rpm and torque from this engine. This is basically a theory right now, I can't just go do this right now, but I would like to build race engines with f23blocks in the future. So, am I crazy right now? Would the piston immediately smack a valve if kept mostly stock? I would plan to run methanol in this engine, octane rating should be sufficient.

I'm almost positive this has been discussed before. I believe they ran the rsx type s pistons instead so they wouldn't blow up their motor. SEARCH

Point is I want to run type r pistons with stock stroke. Is it at all possible?

Yes, you will just need to mill out the head for the extra clearance needed for the piston itself.

Exactly what he said. It's a lot of work so you have to ask yourself if it's really worth it.

It's just an idea and I just tell myself it will be fun in the end. It's less drastic than what my stepdad does for his mopars... Domestic cars pfft!

Guess you haven't done any research at all. Good luck with the build.
