I recently bought a H22a throught H-motors. I am wondering if there is a way to visually determine whether the motor is jdm or usdm and if it is 92-96 or 97-01. I was under the understanding that it was in fact 92-95 jdm vtec. I know its vtec, but I wanted to be sure it was 92-95 jdm. Can I reference the number on the block? I also want to know if I have the right tranny. Auto tranny in it, code is MP1A. Is this the right tranny for an h22a? Whats the difference b/w this and tranny for f22 or is there a difference?

AHHVTEC · 12-04-2006, 10:07 PM

well if it says h22a its jdm if it says h22a1 its not

chaindtoarock · 12-04-2006, 10:12 PM

Ok, so tis definitely jdm, that was easy. Do u know how to tell the year?
Or the tranny?

AHHVTEC · 12-04-2006, 10:34 PM

yea if is a obd1 its 1993-1996 97+ will be obd2

How do I tell if it is obd1 or 2 if I dont know the year for certain? The motor is already in.

Also the tranny is shifting pretty hard at low speeds, is this just the nature of this tranny (MP1A) with the torque of the h22a or might I have a loose motor mount, or worse a bad tranny? When I am slowing down it drops gears at about 5-7 mph and it is a pretty hard shift. When accelerating quickly it is nice, but going up the gears more slowly the shifts feel like a bad shift with a manual tranny.

Sounds like a bad trans to me, had the same thing happen in an older car i had and after about a month of 2 hr drive to work and 2 hr return trip i lost 4&5th about 45 mins into the drive home one day. . . drain your tranny fluid and look for impurity's maybe? i figure its cheap and once u rule out the tranny being bad you can stop sweating for a little bit

chaindtoarock · 12-06-2006, 06:54 PM

I just replaced the trans. fluid and it looked ok. Im thinking is a bad tranny. What I am looking at to convert to manual? What tranny etc.

chaindtoarock · 12-06-2006, 07:06 PM

I looked at the tran specs page. Is it worth the money to get the lsd if the car is not going to have crazy hp/torque. Will not be racing, just a daily driver.

Will I have change or adjust anything other than the tranny itself and running the pedal?

Im still not sure whether it is 92-96 H22A or 97+ H22A so I dont know whether to use M2B4 or M2Y4. I dont know because I was told it was to be a 92-95 H22A when I purchased the motor, but after the motor was installed I am getting an engine code that says ABS not found (or something like that). 92-96 didnt have ABS, right? So is it possible I got a 97+ H22A.

egoSH · 12-06-2006, 09:23 PM

chaindtoarock · 12-06-2006, 11:55 PM

No, it says H22A on the block, so is it 97+?

powerdriverh22 · 12-07-2006, 02:28 AM

on the head there are things that look like clocks and those will tell you the year and month etc

powerdriverh22 · 12-07-2006, 02:30 AM

h22a means jdm h22a1 is obd1 usdm and h22a4 is obd2

daveyboycd6 · 12-13-2006, 12:28 AM

there is a stamping in 3 separate circles like in a clock style with arrows pointing to day, month, year. for manufact date, cant member where i saw it tho, im sure someone remembers

powerdriverh22 · 12-13-2006, 03:05 AM

rich045 · 12-14-2006, 10:07 AM

you can also tell by the dizzy, on the obd1 h22a you could adjust the timing (the holes for the dizzy are oval) and the obd2 h22a the timing is set, you cant adjust it... which kinda sucks

Nickg4c · 12-14-2006, 01:38 PM

Yea, I noticed that on my obd2 h22, We went to mess with the timing and found that only two of the holes were oval, so we couldn't adjust it. Any idea why that is?

reikoshea · 12-14-2006, 01:48 PM

safety precaution, and you can adjust it with a computer like Genesis, but no more turning the distributor to advance the timing.

Nickg4c · 12-14-2006, 08:15 PM

Too bad, but its a wise move on honda's part.

brazillianpimpx · 02-15-2007, 03:39 PM

Bro don't worry about it being a bad tranny... it's prolly not. Although honda is known to have tranny problems in upwards of 100,000 miles, it's prolly not cuz i've driven that car plenty of times and that tranny just KICKS when you go slow... it's a hard working tranny becuz of the engine thats atached. when you step on it it's smooth, but when your just riding out slow... it's pretty rough... or maybe my girlfriends cars tranny is bad too? hmmm who knows? all i know is that her cars in perfect condition and its very unlikely.

Mulepick · 02-15-2007, 04:58 PM

Did you put the VTEC TCU in with the VTEC trans or did you just use the old one?
