87 zc-1 crx to d16a8 swap
First let me introduce; i live in Portugal and i own a beautiful jdm 1987 crx that had until last wekkend a zc-1 engine (olive top).
This car has been the joy of my life for years and it was almost all stock.
Great low end torque and plain acceleration until 7000rpm.
1 month ago i was on the freeway running the usual 230kmh (tach) for 40km and then it blew.
I was kind of suspecting that something wasnīt right... itīs the problem to those that donīt check their rod bearings often...
Nothing was broke inside, but the crank, 1 rod and the block were damaged what brought me to have to buy another engine.
I looked for 1 month and found a rover 416gti with a d16a8 and a pp5 ecu that had 47000km on cluster from an old man.
I bought the engine and swaped it in my crx.
A lot of work had to be made. Mod engime mounts, adapt the zc-1 gearbox to the d16a8 block, adapt the starter, adapt the alternator mounts, adapt exhaust header, etc
Now i face a scaring task. (at least for me)
I did all work, but now i donīt know what to do to adapt the ecu and engine wires.
I had a pj1 ecu on my zc-1 with a vacum advance distributor.
Now i have to change it to fit a obd0 pp5 ecu where the pj1 whas and change the connections to the engine wires.
I have the complete engine harness with plugs, the problem is that the pre-obd0 wiring that my car has is diferent and the connectors are all diferent.
Can someone help me?
I know that itīs quite a lot comming from a new user, but next weekend i really want to have the car running.
I need it as itīs my only car.
Thanks!

why not use your old harness & ECU on the A8 - use the vacuum advance distributor - it doesn't bolt on to the A8, but if you take the #6 intake camshaft bearing cap from your ZC and put it on the A8, you can get two bolts in the distributor instead of 3, but 2 will hold it fine

I have an 86-87 Si (vac advance pre-OBD D15A3) to 88-89 Integra (OBD-0 D16A1) wiring chart on my computer if you want it. It should give you most of the changes from Pre-OBD to OBD-0.
