? about h22a1 block

ok, so im in the process of rebuilding my h22a1 (with the help of a friend) and i noticed that one hole on the block where they trany gets bolted to is completely stripped (previous owners fault) so i was able to find another h22a1 block for next to nothing. theres p5p pistons in the block i have now and i was just thinking of swapping them over to the other block i just got, now my question is, on my block it has BBBB on it and the one i just got has BBBA, am i or what problems am i going to run into? i just bought a rebuild kit off this guy for a great deal who was going to rebuild his h22a1 but sold the car before doing so. thanks in advance for the help.

Re: ? about h22a1 block

The letters are from when the block was manufactured. Honda had A pistons and B pistons. They account for the small differences in the casting of the block. H22's came blueprinted from the factory. That's also why they have all the different bearings. When u order them thats why they have different ''colors''. BBBB means the whole block was b pistons. BBBA means your number one cylinder was an A in your other block. It should be stamped on the middle of the piston what you have. I'm not sure what can happen if u switch them. Your ring tolerance might just have to be closer. But u have a bunch of b's. just inspect them well for cracks and what not. I'm not an expert but i hope that kinda helps.

Re: ? about h22a1 block

i know that "BBBB" and "BBBA" have to do with the pistons but im just wondering if im going to be able to use the type s pistions that i have in my original block in the block i just bought or if im going to have to get different bearings or different rings then the ones i already have. im probably sounding a bit dumb but im not to savy when it comes to engine internals. thanks for the help

Re: ? about h22a1 block

Gotcha, Well for type S pistons u need to have the rods need to have bushings for floating wrist pins. I screwed up bad by not doing that. Look for some of my threads. There are pics of the aftermath. They will work despite the A and B deal. Just make sure the rings are in spec. Take the feeler gauge and measure their gap like it says in the manual and u should be fine. If u dont know what i mean i can elaborate or send a diagram.

Re: ? about h22a1 block

well, the wrist pin that connects the piston to the rod is supposed to be different than what came in a USDM h22. I didnt have that done and it locked up and exploded one of my slugs and scored up a cylinder wall horribly.. Its hard for me to explain. there are other threads on it in here and in other forums.. I dont know if the person b4 u did this right either. But to be safe maybe take them apart and have a good machine shop that knows look at them and or do what they have to do to get u running. I'm just trying to help by what crappy luck i had and no knowledge.

Re: ? about h22a1 block

Well the a and b deal is just for the bore. Its such a small difference. As long as the rings are filed down within spec ur ok. Ur sure the rod ends have the right bushings right? Also that a and b bore difference has nothing to do with the bearings. Thats its own can of worms. Here are some diagrams to try and help. Thats really all i got, someone will help. U have a haynes manual? there is a link on this site some place to download it for free.

Re: ? about h22a1 block

as far as i know they have the right bushings, the engine was running before we pulled it apart so im guessing they worked fine as far as manuals, no i dont have any. those diagrams are helpful, thanks alot for them. you think you can email me them? ill compare both sets, old rings, bearings and the new rings and bearings i have tomorrow. i will get back to you after i have done so. thanks again
