Hello everyone, i need your help, I have a 89 honda civic and I just bought a vtech engine that came from a 94 civic. the 89 engine is 2 injectors and the the 94 is 4 injectors. How do I convert it from 2 to 4. Can anybody tell me what to get and how to install it?

 

That is known as the DPFI-MFPI Conversion...search it on here...thats the most oftenly asked question here.

 

there are a few good sites for that with complete write ups, i just cant sit here and write step buy step but you need to run 4 wires from the ecu to the engine bay move 2 wires around at the ecu get a si dizzy and a si or ls ecu and a resistor box and your ready to go, or you can get the 94 dizzy ecu o2 and get a rywire obd0 to obd1 jumper, whatever the case i can make you a very nice engine harness for either application

 

dont use anything els
