I just got a car from a buddy of mine you tried to swap in a DOHC ZC. The car is a 1991 ef hatchback Si. Here is some of the issue with the car that have me concerned. The fuel rail and injectors are off of a d16z6, with the resistor box removed. The throttle body has a TPS but it also has the MAP sensor on the firewall too, he has the plug plugged into the TPS. The motor has no cam angle sensor, he said it was built into the dizzy. I tend to beleive that the dizzy is a OBD1 dizzy. When i start the car up, it runs like poo. I can hold the pedal to the floor and in spits and spudders and if it can muster the strength it will rev to like 3k RPM and then sound like it is banging off the rev limiter. Sometimes I can rev it but even if i hold the pedal wide open, it will not gain RPMs at all just hovers around 1800 rpm. The harness is hacked up but I dont mind soldering to fix the harness. The dizzy has the plug cut off along with the dizzy plug on the harness and spliced in. The main question I have can I use the OBD1 dizzy and the ODB0 harness, and if so what colors do I splice together. Also do i need the cam angle sensor. And can i use the injectors without the resistor box. I appreciate all the help I can get, cause this thing is needs to be my daily driver.
