another one of those great mysteries to me... is it *really* OK to run forged pistons (srp or je) in a stock (re-honed of course) h22a4 (5th gen prelude, with the frm crap in the cylinder walls) motor?

given moderate amounts of boost, i think i may not build the whole thing (i.e. sleeved, decked, o-ringed, rods, pistons, blah blah blah) but just toss in some stronger pistons and rings.

 

this topic came up in teh Prelude forum a while back, but the search isn't working properly... try checking there...

 

looked thru everything available now, couldn't find it, remember what the verdict was?

 

you cannot run forged pistons in any H22 or H23 motor w/o resleeving it. if you're not going to boost much, then just keep your stock bottom end. it can handle it if you put the tune on it.

glad i caught this before i put my je pistons in whew!! so what is the real story on what happens. Does the pistons weld themselves the the cyl walls after time?
