PC-9 Holds Tough - Honda Prelude Forum

quote: In a 4 cycle, the coatings do not tend to swell as much and it is rare to see the coating wear unless there are several thousands of miles on them. At the trade show, we have a diesel piston that has over 250,000 miles on it and the coating is still nice and dark. : quote

I have been looking into this stuff for a while now, if it holds up in a deisel engine for 250k miles, and the coating is still there, its reliable. Who wants to be the first to try this on the skirts of forged pistons to go in stock sleeves? I would do it soon, but I am waiting till my warranty is up before I swap out any internals. That was the only stipulation I got from the dealership.

are you looking for someone to experiment with pc-9 or something, im confused on what this post is for

Its an option to resleeving the block. We werent sure if it would hold up for a an extended period of time, lots and lots of miles, but Swain has shown that it does.

Have they shown that it works on our sleeves?

They have said its worked on several hondas.....havent heard about the N20, but if its turbo capable then N20 must be ok

Yes, they have done it on Preludes, and a few NSX's. We new that it would work as long as it holds up. By doing this, we can run forged pistons in our stock sleeves, which cuts out the cost of new sleeves, and will also lesson the labor charges. My warranty is up in about a year, thats when I cam going to drop in forged pistons and rods.

I'll still be sleeving my block. I'd rather do everything right once. If I had an H22A4 I would seriously look into running a blockgaurd if you aren't going to sleeve the block.

Block guard is a must if your not resleeving. Simply running forged pistons and rods will not allow you to safely run 150 shots, 125 is probably the shot I would run. This PC-9 coating simply gives you an engine that will last longer, and hold a slightly larger shot than would be recommended for stock engines. Its an option......

Laughin, do you know(dumb Q) if you can stack block guard, just wondering even though i doubt its possible. Id resleeve also, but you could run 10.5 or 11 to 1 forged pistons and rods with a block guard and rund a 125 shot and probably be alright....thats all I want.....much more than that isnt necessary for street.....youd have good all motor power plus a fatty N20 shot....just my .02

Stack blockgaurds? Can you explain what you are thinking exactly?

NXLude · 12-16-2002, 11:42 PM

Maybe I am confused at how a block guard is installed, but i dont think so. It just is tapped into the open water jacket right? Would it be at all possible to stack one on top of the other to make a ghetto solid sleeve? I hope you see what i am saying......just picture putting the block guard in and then another on top and another on top and so forth.

laughin2.2 · 12-16-2002, 11:58 PM

You mean putting one inside of another and so on? Wouldn't that be the same as sleeving the block? I honestly don't see it being cheaper than sending the block to gold eagle to get sleeved.

Toretto · 12-17-2002, 04:29 PM

A single block gaurd will be sufficient for what your doing. ANd Laughin is right, block guards are about 150-200 each, can add up pretty quick.

NXLude · 12-17-2002, 06:32 PM

I was just wondering. Its a retarded question Ive had for years. I was just thinking that putting 2 in would support the cylinders good enough for 150 shot, keeping in mind Id probably be sporting eagle rods and coated forged pistons......Im just thinking of a budget buildup.......
