Few Quick Questions
Hello,
Okay I have 1991 CRX DX with the stock engine in it. Recently it started to smoke we have done everything we can and it turns out it is the Piston Rings. So i would like to take this oppurtunity to Swap the Engine. I've come to the conclusion that i would like to Swap the JDM SOHC VTEC D15B engine with a P08 ECU and a OBD-OBD1 Conversion harness.
Here are my questions
1.) When i wire for MPFI, in all the how-to's i've read it says to use the SI ECU and SI MPFI Set up. Can i use the MPFI setup on the engine i bought (D15B) and the P08 ECU instead?
2.) will there be 4 injectors allready in my Engine (D15B)?
3.) what is a injector resistor box?
4.) How much will the MPFI conversion cost?

1.) The reason they say use the SI ecu is because they are keeping their stock engine and just wiring from 2 injectors to 4 injectors. You are NOT keeping your stock engine, so you will use the P08 ecu. You are going from OBD-0 DPFI to OBD-1 MPFI.
2.) On the JDM vtec d15b there will be 4 injectors.
3.) The injector resistor box recieves voltage from the ecu and the box will reduce the voltage and send it to the injectors because OBD-0 MPFI injectors are low voltage. OBD-1 injectors are high voltage injectors and WILL NOT need a resistor box. However, if you want to save yourself some wiring trouble, you CAN run the P08 with OBD-0 injectors with a resistor box, or you can just run the obd-1 injectors without the box.
4.) Depends on the deals you can get.
