Hello everyone, New to this forum, but not to Honda's or CRX's. I've done some wrenching on my current car over the past 6 years (minor stuff only), but I'm now swapping the motor and need some help. I've searched both this forum and the internet in general, and am more confused than when I started. The stats: Car - 1990 USDM CRX Si Current Motor - D16A6 1.6L PGM-FI ODB-0 New Motor - SOHC ZC (non-VTEC) 1.6L PGM-FI ODB-1 (is ODB-1 correct?) Reason for the swap - The current motor has 211K miles, blew a head gasket at 140K miles and was fixed at a Honda delaership. Car has been slightly overheating during hot days with the A/C on since the repair, but for the past year it's been burning oil and coolant. And now it's really bad, D16 won't last much longer. I think my head was just slightly warped after the HG blew, and Honda didn't fix it properly. I have confirmed low compression on cylinders 2 and 3 (1 and 4 are within spec). Monday I ordered a ZC SOHC non-VTEC from ACE in LA, and it arrived yesterday. Here's what I plan to do: - Swap the intake/exhaust manifolds from the D16 to the ZC (will have new gaskets for both). - Keep the current Si transmission and move the flywheel to the ZC (and putting in a new clutch) - Swap the main belt pully from the D16 to the ZC (motor came with a Power Steering pump, taking it off and swapping the pully because the ZC one is rusted) - Install new water pump, thermostat and timing belt on the ZC - Swap the Cooling Fan Switch connector from the ZC to the Si wiring harness - Use the alternator from my D16 Now here's where I'm confused, as I have found conlicting info on the net. Could someone here please give me definitve asnwers for the following: 1. The ZC did not come with a Distributor. Can I use my D16A6 Si distributor on the ZC? If not, do I have to get a dizzy from an 88-89 Integra? 2. Can I use my Si ECU, even if I have to change the dizzy, or must I swap that too? 3. Anything else I need to know about this swap? My niece's husband works for a Honda/Toyota repair shop, and he's been working on Hondas for several years, so he's going to help me do the swap. But he's also stumped on these questions, and none of the shop manuals cover swaps. I'd like to get the swap done in a single day, so the more prepared I am at the start, the better. So I'm trying to gather a list of all the parts I'll need to get this done to avoid driving back and for to the parts dealer, or trying to find stuff online. Thanks in advance for your help.
