hey all....can anyone help me find the wiring schematics for a D16A motor, or the Vehicles that they originally came in so I can track it down. also...what kind of headache it will be to drop this motor into a 86 CRX?

 

If you are talking about the d16a1 from the early integras it will drop right into an fuel injected 1st gen crx. For wiring schematics I would suggest getting a helms manual for the early integras. They are only 50-60 bucks and a worthwile investment.

 

if it is just D16A (no other number following A) it is a JDM OBD1 SOHC VTEC engine which is basically identical to the D16Z6 - you could put it into 86 CRX - would not be easy - you would have to fabricate just about everything from mounts to shift linkage - get custom axles - do major wiring - if you don't have Si model, it gets even worse as you would need to replace the entire fuel system - if you are talking about a D16A1, then much easier.

 

ok...this is what is confusing me....the markings stamped on the block are D16A......but the head on it is a DOHC......so any ideas you might have would help out a lot!

At the top of the family tree for the D Series, DOHC 1600cc, 16-valve engine is the JDM spec ZC engine of 135 hp. Next in line was the Euro-spec D16A8 which makes about 120 hp. In the US, we got the D16A1 Black Valve Cover version in the 1988-89 Integra, with 118 hp. And at the end of the line is the D16A1 Brown Valve Cover version in the 1986-87 Integra with 113hp. Many people refer to all 1986-89 Integra engines as being a ZC, but this is not technically correct. ZC is Honda's term for the top rated version of any family of engines. Not many people realize that there was a ZC version of the SOHC D16 engine that was sold in Japan. If you can find all of the JDM parts, you could build a USDM D16 into a ZC. But those parts are rare and probably expensive. The Brown and Black valve cover version of the DOHC D16 engine are very easy to install. The 88-89 Integra engine (black valve cover) is slightly more powerful than the 86-87 engines (brown valve cover) because it has a better flowing intake manifold, domed pistons with higher compression and lighter connecting rods. The black top D16 has a very different distributor and ECU that will not “just plug-in” to a 1st Gen CRX. You CAN NOT use the brown top distributor on the black top engine. The BROWN Valve cover is equipped with: -Flat top pistons -Thicker rods -Square styled intake manifold -Vacuum advance ignition with external coil The BLACK Valve cover is equipped with: -Domed pistons -Slightly lighter rods -Rounded intake manifold. -Electronic advance distributor with internal coil. ACTUAL SWAP INFO: Engine Mounts (total of 3 mounts on 84-87 Civic/CRX's): Use the stock Civic/CRX mounts on the rear cross member & front timing-belt side. Use an 86-89 Integra tranny mount for the tranny. The Civic/CRX tranny mount will make the motor sit crooked if you use it, so don't. Axles: Use a complete set of 86-89 Integra axles including the intermediate shaft. Knuckle/hub assembly: In order to use an 86-89 Teg' engine + transmission, you have to use the 86-89 Integra knuckle/spindle assembly so that you can utilize the Integra 3-piece axles. The 86-89 Integra axles DO NOT plug into 84-87 Civic/CRX knuckle/spindle's. Shift linkage: Use a complete 86-89 Integra's shift linkage. Wiring harness: Use the 1st Gen CRX Si's wiring harness. Plugs right into the 86-87 Integra sensors, injectors, & distributor. Distributor & ECU: Make sure you use an 86-87 Integra ECU & Distributor. That's the only DOHC ECU (besides a JDM one) designed to work with a Vacuum Advance Ignition (distributor), which only came on the 86-87 Integra's. ***Do not use an 88-89 Teg' ECU or Distributor**** Simply because it has an internal coil ignition just like all the 88+ civic/CRX/Integra use, which is completely different than the 86-87 ignition components.
