No not really, its pretty close to honing Al cylinders, I would just follow the manufacturers instructions. I've done it, use fine stones, on the higher end of pressure, and low rpm, iirc like 40rpm.
Youve honed a H22?
Jonny: Were not talking about bowtie redneckdom.. The frm is different... different than AL as well Dave. Its a well known fact the FRM sleeves are a motherfucker to get done correctly.
Id STILL gravitate towards the info I gave you bean boy, If you have any serious questions you want answered as to why, I suggest getting in touch with someone from say Mahle, or a REPUTABLE machinist.
Hs like to smoke due to the frm sleeves... Fuck up the hine and youll have a really really gay smokey bitch
I know about the FRM issues and I know a little as to why. That is not my question. I KNOW I have to look for a shop that does these, I just don't know WHICH shop does. That is the issue. I've known from the start that FRM is a different process than ductile iron. The issue is finding those fucking shops.
I've honed ductile iron sleeves before without issues as well still using std pistons. I think robert is full of shit. That, or he is a super perfectionist that wants the cylinders 110% round and sees 99.358% as being very out of round so he has to remove more material which causes you to need a larger piston.
I'm a little iffy on going with Auburn Auto. They say they do have the different stones to do it, we'll see. I'll keep doing my research.
And this isn't for me. It's for a customer. Stock H22 block/head stroked with f22 crank/rods. THe motor is ready to put back together, asides from needing to first size up the bearings and the hone.
