omg, i just spent some money on some high compression pistons. JE 12:5... My friend opinion said, i think you should sleeve the block. and now its in my head. really annoying. do i have to sleeve the freakin block? is it a must? i just want around 270 whp. i dont want to spend anymore money at all... what you guys think or recommend?

engine: h22a obd1 87mm bore

 

Yeah, you will need to sleeve it. Those pistons wont work with FRM.
Only Mahle make pistons compatible with FRM.

 

And so does Honda.

 

^ Obviously.

 

you HAVE to resleeve with those Pistons. The rings will chew up your stock FRM sleeves like it was nothing. A few thousand miles and get ready to welcome a new engine.

The only forged pistons that can run with the stock FRM sleeves are the Mahle Gold series.

 

I think its funny how people these days will just throw down the money for the forged pistons without understanding the FRM cylinder issue. It's like this situation hasn't been covered over and over.

 

^^^^^ yea the people selling them in import shops should know too if they dont go somewhere where they do know about FRM

 

Beginners

Lemme guess, you're trying to make 270whp on a budget?

 

/uselesspost

 

thanks for the help. appreciated.


Yeah I'm a beginner, dont hurt to ask forums. Next?


Useless comment. Go troll somewhere else.

I also think its funny how people these days just reply with useless remarks and comments. Thought this forum was suppose to help people out. I'm not a Mr. Know It All like you.

 

It just doesn't make sense to me that you would invest money into parts without knowing whether they would work or not.

I don't mind if people don't know things. That's the purpose of a tech q&a forum. But when the information out there plainly states that you can't and shouldn't use forged pistons with the FRM cylinder engines, and you buy the parts anyway without putting in any time into research; then you're sort of open to comments and remarks.

I apologize for saying it was funny, because it's not. I pity you more than anything.

At least you didn't have them installed and then run the engine.

 

OP, you need to read a bit. I suggest searching some in the All Motor forum as well as this forum.

 

Your post is ridiculous because anyone who knew how to search wouldn't have bothered wasting space with a useless post. NEXT!
Spoon feeding you 10yr old info isn't going to happen here.
You're a grown up, learn to eat on your own.

 

Reticence is your savior. Stop it.

 

I think this is the issue. "Just" 270whp n/a is not an easy feat. If this was turbo, that would be a different story, but he already said he bought high comp pistons, so I can only assume n/a here.

OP, 270whp will cost you money, period. 215whp can be done on a "budget" (~$1k+). I would guess most people are surprised that someone who is aiming so high is doing such little research. You should know EXACTLY why you chose each and every part in a build like that.

do this....since your goal is very possible i would sell your JE pistons for some mahle high comp pistons since they will work with the stock sleeves and that would save you the trouble of re-sleeving the block... your gonna need better rods, machine the crank, racing bearings...ect. and thats not just the beginning...best of luck
