Re: differences between a d16a6 & d16y8 (2k1 GSR)
d16a1 (dohc ZC 1st and 2nd gen) - 87-89 integra 1.6 dohc. Block is very similar to the a6 but one head bolt is different. ~130hp
d16a6 (sohc ZC 1st gen) - 88-91 crx/civic SI. 1.6 sohc-non vtec. Made like 106hp
d16z6 92-95 sohc/vtec 1.6 litre. Made 124hp
d16y7 96-00 sohc/non-vtec 1.6 litre made 107hp
d16y8 99-00 sohc/vtec 1.6 litre made 127hp
those are the important ones. You can swap just about any part on any other part. The only weird ones is the a1/dohc ZC blocks since they have one different head bolt. However you can swap pistons to any block listed above.
The heads all bolt to any of the blocks (again not the dohc blocks). So you could put a y8 head on a a6 block. The z6/y8 flows the best out of the group. The y7 is better then the a6 for the non-vtec group. Between the y8 and the ZC dohc head..the dohc has a better exhaust flow while the y8 has a better intake.
As far as cranks and rods..they are all identical.
The y8 has a knock sensor, the only one. The y7/y8 also have a crank angle sensor which the other blocks didnt.
what else do you wanna know? I could go on all night.

The D16A1 is the teg motor from 87-89 ( I am not positive on the full years produced) it was a DOHC that was similar to the ZC, but different. It made 118hp. Alot of people refer to them as the USDM ZC, but it is not technically a ZC motor. The ZC is either the "ZC" from Japan, or the "D16A8" or "D16A9" from Europe's Land Rover's. Sorry for teh OT post, but.........

yea your right. i couldnt remember all the specs for the ZC. They are pretty close and most parts can be swapped between them.
Thanks for the facts
