how thick is the frm coating on a stock cylinder? I don't think you can bore it at all without completely wasting it. In that case any after market piston would work because it wouldn't be coated anymore. I could be wrong and please say if i am.

 

FRM is not a coating

 

x2.

just a super picky honda sleeve that is annoying. god if it was just friggin iron we could toss in pistons so much easier.

figures i go from a h22 frm motor to a s2k frm motor. ghey.

 

OT: I heard talk of the Mahle pistons for the F20C in the works, but I haven't heard anything more.. Does anybody else have any information regarding these? I find that the FRM designs have been proven with FRM sleeves, and seem like a viable sollution for a low-compression engine that isn't too expensive.

Okay, sorry, back on topic!

 

They are available.. pm me for info

I have a motor going together with these .. should be done this weekend

 

PMed Can't wait to see it running.

 

But wadzii you said they were the NA high comp ones that are out, correct? If you're putting together a low comp motor then please post the results in here!!!

 

mine are high compression, but they do offer low compression as well. there are parts avalible from 8.5:1 up to 14:1 depending on which crank you use.

the low compression parts are made from 2618 alloy, the high compression parts are 4032

 

i would love 8.5:1. more boost possible.

 

Are you going to post a build thread for your build?
