this is a dumb question but will any 97-01 H22A/H22A4 work as a direct replacement? i need to replace my motor only, should be able to keep the harnesses, ECU, etc from my current motor as they're fine...just wondering what to be looking for exactly as some H22s i've seen have stated they will not work with a Type SH...

 

If your H22 has an ATTS system then no. You will need to purchase an H22 with an ATTS system as well since the block has provisions for that specific system.

Here is what an H22 with ATTS looks like:

 

just what i needed to know, wasn't sure if the block itself was ATTS specific or that was a tranny related thing, thanks
