obd2 LS into 1989 CRX Si wiring questions!
 
OK, I know someone just asked about a 91 integra and b20z swap but I need to know any differences.... As it states I have a 1989 CRX Si and I found a B18B with 48,000 miles on it so I am thinking obd2 since it has to be newer but he is gonna check because he doesnt know. NOW, does anyone on honda-tech make an obd0-obd2 harness or no? Tell me what you think and if it would be worth it to pick up the motor for $500.......switch everything to obd0 or obd1 or just try to work with the obd2 because of money issues, not alot to play with.

Just use all OBD0 parts to simplify things. I have a 91 CRX DX with a 96 B18B1 and I used a 91 Integra PR4 ECU and distributor, and then 90 CRX Si injectors and resistor box. Going that route will save a lot of headaches.

go obd1
4 wier O2's are your friend
get a OBD0 TO OBD1 ECU harness from blown hatch use your stock crx engine harness and pull out the resistor box if you use the OBD2 injectors

buy the motor, change the distributor, and get a pr4. the price is good for the motor, beying that is an si the wireing is much easier than you think. stick to OBD0 if money is an issue!

Just transfer your stock engine harness onto the LS motor.
