I am looking at a supposed 88 integra d16a3 zc dohc but looking at the forms so far I haven't been able to locate a d16a3 which is beter a dohc zc or this igrera engine that I intend on putting in my 90 civic dx with a ghetto turbo kit?

 

d16a3? I have never heard of it? are you sure its not a d16a1?

 

If your gonna go ZC do the ZC from the civic not the integra as the integra uses different tranny, etc. the civic ZC bolts right in, which is nice cause u can use the DX tranny. I had one in my 91 DX SE and it was just a matter of ECU and a little wiring change. What a difference from the 1.5! The ZC is also pretty cheap, i got mine for 800 cdn and used the 90-93 integra ECU. Total cost was 900 bucks and took about 6 hours from start to finish!

He speaks of the D16A1 I'm sure, neither are perfect for boost, but either will work. The JDM ZC will be better b/c the tranny thing, but also b/c the turbo manifold, the HF/Std. trick will not work on the USDM D16A1 b/c the exhaust manifold bolts are differant I believe.

I've heard it is a great pain to fit the D16A1 into a 88-91 civic anyway, I've also heard they bolt right in the older CRXs...

 

The D16a1 can use the HF/STD manifold no problem..
