Sorry,but factory manual say`s the RC has two oversizes 0,010 and0,020 inch.How you can rebore ceramic coat.The cylinders are a composite ceramic, so if you bore them, you'll need to have them replated by companies that specialize in that, such as Millenium Technologies.
You can have the heads ported. Hord Power can do this.
Don't have any info on turbo'ing RC51's.
I'm going to have to ask if you can provide a little more info on this.
But i pointed that the cylinders are made cast iron, not ceramic coated.what more info do you need?? i think thats all you need to know, especially when thinking of your previusly posts, i think that´s all the info i want to share with you, i just wanted to point out that a big bore is possible
hi franzBut i pointed that the cylinders are made cast iron, not ceramic coated.
if it´s my you refers to, then i must assume that you are retarded, because thats not the issue here, i got angry becayse two well know atagonists try to be the forum police, and call the shots here, i merely pointed out THAT A BIG BORE CAN BE DONE, it´s NOT impossible, than i got attacked, please get someone who can read to read the posts out loud to you, and explain the difficult words BEFORE you type some crap you without any references to what been said before...ok..dickcheese?so your upset because someone pointed out that a big bore setup might not be cost effective to a regular guy in his garage? Thats basically what was said. Your challenging peoples intellect when it seems like all you can do is read. You said yourself you didnt build the motor you just read a dyno.. How much do you think Morawaki dumped into that thing not just in parts but in R and D? As a guy that has used forced induction on cars I can tell you I can get alot more power out of my RC than that with a junkyard turbo setup.. But IMHO its got plenty of power with a few bolt ons.. Aircooled had an opinion and based on some of his other threads I can see he actually does own a set of wrenches so why dont you just relax tough guy..
I wouldn't worry about port and polish if you're going to turbo. Is there power to be made if you do? Of course it'll have a LITTLE more power, but the cost isn't worth the benefit as the RC51 heads flow fantastic in the first place (Plus I doubt the difference in spool will be notable if you properly size the turbo). Same thing goes with increasing your cylinder size, it will yield you a little more power and a little better spool but not enough to where I'd go out of the way to do it. I've already turboed plenty of applications and the good setups are always the simple ones.
