I know this is a weird combination and not recommended, but it's already been started and close to finish.
i had a b16a2 in my 96 ek, but the head gasket blew. I took it to a local "performance" shop and they said if i let them keep the motor they'll give me a b16a1 long block and labor for free. Just for reference, I have the following parts: 96 DX harness with HAsport overlay harness (for the extra wires), ITR intake manifold, OBD2 distributor (for the obd1 motor) OBD2-1 clip and a p28. Basically everything around the motor is obd2 but managed by an obd1 p28 ecu. The problem with the swap is that they cannot just plug in a diagnostic computer and see what the problem is because it's such a cross-breeded setup. OBD2 car, OBD1 ecu, OBD0 motor.
I know that the ignition system have no problems at all. The problem lies in the A/F system. I bought a Apex'i VAFC but it doesn't help the richness at all. I test drove it today and it runs like total shit, around 1000-2000k rpm the engine is running extremely rich, the whole car stutters with black smoke comin out of the exhaust, but at full throttle or anything over 4000k rpm the engine runs like a champ.
all the sensors are supposed wired, but the shop is going over the pins to see if there's anything wrong with the setup. The only thing I have that's OBD0 is the throttle body, and from valve cover to oil pan, everything else is OBD2.
Can the OBD0 TPS sensor be the reason? there's only one vaccum hose on the obd0 throttle body, tried to plug that somewhere but it doesn't seem to matter.
The shop and I have tried pretty much everything, tried a obd2 b16a ecu and it runs the same.
It's too late to swap the engine for an obd2, for one I'm flat broke and I've been out of a car for a long time now.
If ANYONE might know what the problem might be...please help me.
thanks.
