Please Post D16A1 Swap Info Here

ok i guess i'm a little confused... are the pistons in the 88-89 integra d16a1 the same ones that are in the civic zc 88-91? I alson noticed on an engine chart the d16a3 is rated at 118hp and the d16a1 is rated at 113 but it shows the d16a1 to be out of a 86-89 teg and the d16a3 to be out of an 88-89 teg? Just want to make sure i have the right pistons and rods before i start building the engine..

No matter what you read, ALL USDM '86-'89 Integra motors are labeled as a D16A1. There is no such motor as a D16A3, however the EDM versions of the DOHC D-series motors are labeled as D16A8 and D16A9.

The '88-'89 D16A1 pistons are the same as an '88-'91 Civic ZC.

Almost all of the internal parts are interchangeable between the DOHC D-series motors and the DOHC ZC motors, with the exception of the '86-'87 D16A1 oil pump and the Civic ZC crank and cam gears.

thanks! BTW your car looks awsome! Although I've had many many honda projects this is my first 1st gen so I'm trying to learn a little. I think my setup on the engine will be somewhat similar to yours as far as the parts go. I'll try to post some pics soon.

ok srry this is sorta off topic but i have a 3g civic, 84 civic 1500s hb. i dont know the engine code, for some reason it is very hard to find, but i am interested in a mini-me swap. i have done a little research and it looks like the D16Y8 will fit my engine block. im not 100% sure about that so, is there any other engine head that will fit my block and give my civic a little more kick? i would appreciate any info! thanks for looking
