I have a h23a1 that I took to the machine shop, they say that it has teflon coated sleeves and if I want to rebuild it I have to get it re-sleeved. Is there such thing as teflon coated sleeves on Honda motors?

 

teflon? not sure, i know they are FRM though.. fiber reinforced something somethings

 

FRM=Fiber Reinforced Metal. Most shops don't have the proper equipment to hone FRM. It is not an easy process to rehone FRM from what I understand. You should do a search on this site to find out if there are any shops close to you that can do it. Otherwise you can just ship your block off to someone like Darton or Golden Eagle to get it resleeved with ductile iron sleeves so you can run forged pistons. Good luck. If you need any more info you can PM me.

 

Thanks, I've search for FRM and I found alot of info on it. Here is were I found some of the info http://www.preludeonline.com/f93/frm...leeving-83579/ hope this helps anyone that is in the same predicament as I am.

If anyone else has anymore info on this I would greatly appreciate it.
