H22A4 Block with an H22A1 Head?
Hello guys probably a stupid question but i just blew a rod in my H22a1 Block and was wondering if i could switch the block with an h22a4 block or what? just any input if anyone has done it before or what. i just found a good deal on a whole h22a4 motor so. that or im going to look for another bottom end for an h22a1

im not too sure about the work required putting an obd 2 engine in a obd 1 car, probably will need a jumper harness.
all h22 heads were the same. as far as i know the only difference bettween h22 heads were the LMA's.
just be sure to use the correct head gasket, the a4 block is open deck while the a1 is a close deck. u need to use the a4 head gasket.

i can honestly say in both preludes ive owned the motors have been strong so dont dispute that fact. i beat the crap outta my old prelude everyday for a year and a half put 20,000+ miles on it and never had a problem. and no twin turboing a 4 cylinder is pointless. people push enough power out of a single turbo on a prelude no need for 2

so i could use the block of the h22a4 and keep the head i have off the a1 such as intake mani etc. and obvs use the a4 headgasket. and have no problems? also no problem with my obd1 wiring harness etc? i know there isnt many plugs on the block just the oil pressure etc.

Re: H22A4 Block with an H22A1 Head?
yeah thats what i figured. i just wanted to double check and make sure verything was straight with all that before i bought the motor for no reason and such. i would be able to keep the same ecu too right?

I'm current putting an a4 block in my prelude and using my a1 head what are you calling the rotating assembly sorry for my ignorance but this is the first car I've ever tackled myself

Re: H22A4 Block with an H22A1 Head?
Crankshaft main journal size makes no difference if you use the ENTIRE short block/bottom end. The A1 head will work just fine on an A4 block... the only tricky part is you need to use the head gasket that matches the BLOCK and not the head. So you will need to use an A4 ('97-01 Prelude) head gasket.
