I recently took my head off to have it worked on and I noticed there was alot of carbon build up on the pistons. I was wondering if there was an easy way to maybe scrape it off or something. Thanks for any help.

ehh its not worth it really its normal for that to happen, you should pull the pistons out and replace with aftermarket higher compression from bisimoto and get that head ported while its out.] -
The head has been ported and bigger valves are being put in
Now when I replace the pistons is it ok to use the rods that are there now or should those be replaced as well. I don't have a big budget right now so i'm trying to get away with what I can.

yeah you can use the same rods they should be fine, unless you have some sort of forced induction. and looking at your Sn it ooks like your using nitrous oxide??
then you would definately want to, and forget about the highcompression pistons if your using nitrous... probly be better off with stock replacements, just forged and then forged rods, although i dont know what gives out first on an f22a i think its the rods so in that case replace them with stock pistons and forged rods lol.]Comment

Nah i'm not using No2 nor am I using turbo. I'm just looking for some good N/A power. I may turbo later on down the road but not sure. Is it ok to turbo on the stock rods?Comment

well it s all about tuning but yes it is o to turbo the stock rods.
and you need to have a goal in mind, because iif yuou build for na for now, turboing a car with higher compression isnt good.
so figure out what you eventually want to do, if you want some good power for now and want to get more later, a swap is the best IMO
f22b or h23 is a great swap to do because it gives u dual cams and better tuning ability and about 30 more hp then your engine has. add i/h/e and a chipped ecu, and youd have some pretty good power.]Comment

Awesome, thanks alot for the info. I'll probly just stick with N/A and think about the swap later on down the road. I'll search around on here to see what kind of rods to get and what-not. Thank again.Comment

Hey peeps
Sorry for jacking your thread man but i got a question.
I got my toped worked like ported n polished, deck shaved, 135 lift cam. I wanted to get better pistons so i wanted to know what kinda pistons would be good. Would a lighter crank shaft be good too.Comment

i think that would throw it out of balance im not sure though.Originally posted by 1993hAccord
also check out bisimoto.com, their are other places just search around for
"f22 pistons" high compression pistons would be best for an NA build]Comment

I would have to say that the bisimoto pistons are deffinately in order thanks for the help.Comment

First off, Why would you want to use stock rods when you are going to be using new high compression pistons. If you are going through all the work just get better rods.
The next thing is, Stock rods have pressed in Wrist pins, Most aftermarket pistons have floating wrist pins.
And about stock F22 rods, They are NOT the weakest link in the rotating assembly. Its the stock pistons, The ring lands are the first to go. Then IF you are lucky and your pistons dont break or melt the rods will break. Then if neither breaks then you will have a nice sized hole in your block.
The f22 rods "can" handle up to 250 to 300ish HP. I put can in quotes because it depends on the condition of the motor, the setup you are using, and the tuning associated with your car.
