H22A4 REbuild...
 

Has anyone here rebuilt an H22A4 ?? I'm looking for honing techniques on the FRM sleeves. Any comments or suggestions ??

sorry cant help ya there. are you doing the rebuild yourself?

never done it, but what are the frm sleeves ?

a brand of sleeves i believe.

yeah i'll be rebuilding it myself if I do it. I rebuild the B-series motors once in a while, but I haven't rebuilt an H22. The H22's have fiber reinforced metal sleeves. You need to run stock rings and cast pistons with them. I was wondering if there are any special honing techniques with these sleeves. I assume there would be.

you cannot use the same type of sleve the h22's have in them if you plan on running new pistons, i am not sure what the stock sleeve is (iron? aluminum?) but basicaly, the fordged pistons will be like rubbing on sandpaper against a h22 stock sleeve, this is one thing i know is a huge difference between b and h serise motors. im going to do some research on your plans though, and report back with my findings :bandit:

in my chilton's manual it says to use just a regular hone when honing them, but then again that's a h22a1

the difference between a h22a1 and h22a4 is mines closed deck, his is open deck, my compression 10:1 his 10.2:1, and if he's putting new sleeves in, i believe he would convert to closed deck... right?

what was closed deck again ?

im not 100% on this, but i think open deck the sleeves arnt connected and theres a space ontop of the block(where a block gaurd would go) and closed deck is like an open deck motor with a block gaurd but one piece, has the oil lines run through the block better i think, and is a stronger design.

makes sense now thanks:cigar:

This is a pic of a 92-96 closed deck H22A1.


And this is a pic of an open deck S2K block. Similar to the H22A4.
ouch !!


The H22A1 is a really strong block design compaired to the H22A4, although the H22A4 has superior cooling because it is open deck.

What all does it say about honing the sleeve in your book ??

yeah.... thats what i was kinda trying to explane.

ouch !!!

the book stops at 95. i think 96 was the last year for the h22a1, then in 97 it became the h22a4

i own the same book, it stops at 95 cause then honda switched over to obd2 i believe. the 96 h22a1 has more in common electricaly with the 5th gens than with the 4th gens i believe

whats going on with the s2k engine? any parts you need to get rid of off of it?

from what i saw in hondas the last year of a model shares so many things with ne next generation more than with the same cars from it's own generation :crazy:

yeah, 5th gen preludes stole ALOT from 4th gens though. engine, suspension, brakes... definitaly not styling though :pfft:
