A guy on ebay is selling an H22 closed deck block that he says the cylinders are scored. I'm wondering is it from the forged internals that he had or the turbo setuo he had or improper managment. Will forged internals on a stock sleeve really mess up the stock sleeve. Just check the clearances and proper actions, right?

 

on a h22 yes you cant run forged pistons on stock sleeevs d's and b's go to town

 

why can't you run them on an h22? I have a closed deck d16 that i'm building and i want to run forged internals, will i be ok.

 

yes the d16 will be fine like i said serach on honda-tech they hyave very informative articles why id ont feel like summarizing

 

what is there to sumarize, the h22's f20c's ect use FRM sleeves. (fiber reenforced metal) if you try to run forged internals it will just chew the sleeves up. it will look like score marks were the sideskirts of the piston hit the sleeves. all b and d use regular iron sleeves so do the f23 blocks and so on

 

There is one company that sells a coated piston for the h22 so it can be used unsleeved. But with. The cost of the pistons, is not going to justify still running stock sleeves.

 

wiseco makes forged pistons specific for H22/H23 blocks and FRM sleeves that work...

the dude most likely just overheated..

 

mahle makes a stock sleeve turbo piston for the h22a also.

 

do you know part number for mahle turbo pistons for h22? are they forged?

 

ahh ---- thats who it was, not wiseco..

yea its forged..
