Hey Guys,
Hoping someone can help me out with these questions about an LS swap.
The car is an 88 crx si, the motor is from a 93 LS Integra, the tranny is from a 93 GSR Integra.
1. What ECU will I need since the 93 is OBD1?
2. What Axles are best to use?
3. I can use my crx si engine harness with no problems right?
4. Would a newer LS (94-00) intake manifold fit on that motor in my car?
5. Anything else I should know about the swap before I start it?
Thanks in advance.

Having just completed an LS swap, I'll chime in.

1. If you plan to stay obd1 you will need an obd1 PR4 ECU
2. Use the axles including the half shaft from any 90-93 integra
3. I did the multipoint conversion since I had a DX to start with, but from my reading you can just reuse your CRX Si harness
4. This manifold will fit
5. Do some more reading/research, the more you know before you start the better off you are.
