it's been done, but for the cost of the work, labor, time, you're better off buying the whole d16a1 and rebuliding it the way you want.

I have both a DOHC D16a1 and an SOHC D16y8,and The A1 has a broken cam and also has pm7 pistons which I am using on the Y8 biuld with a two layer y8 headgasket. DID a compression calculator on this setup and came up with a 13.09:1 cpmpression with a displacement of 1590.59.

Doesn't the A1 head have a bunch of vaccum lines running off it that are kinda critical or something. I can't remember why a bunch of people told me not to EVER EVER EVER use the A1 in a newer car. Dunno best to get yourself a old 87 CRX and throw that A1 in it.

not true because the a1 is just like every other D when it comes to vacume line and wireing.

but it has been done at my school the kid did all the maching him self and put a built y8 block and a a1 head and boosted it but its not worth it. just build the y8.

Yeah I would definately say that you need to find your parts and rebuild that D16A1, cause that will be your best bet. I have run both engines, and will never go back... Right now I am running a D16A9 which is basically the same, and I love it.... But that is just my two cents worth....
