Well I'm looking into doing my first swap, this will be my offical swap progress thread. Hopefully I'll be learning a hell of a lot more and do a kick *** write up on swaping a ls motor into a crx since it's been hard for me to find something thats pretty straight up.


Well, so far I have the car obviously, which is a 1989 honda crx dx. DPFI 1.5L SOHC slow as hell motor. I recently traded some paintball gear for a b18b1 motor out of a 96 or 97 Integra. It came complete with the distributor, intake manifold and engine harness. That same day I got a great deal on some Hasport mounts for $100. This afternoon I picked up a Hasport shift linkage for $80 but it needs some new bushings and stuff. Hopefully if all goes well, Friday I'll have a early 90's LS cable transmission and axles for a b-series swap in a crx along with the halfshaft.

I also read that I can use an OBD1 ecu and convert my harness to OBD1 and run the motor safely like that. I'm still foggy on what exactly to do there.

What else I need:
-ECU, OBD1 PR4??
-Integra hubs. What year?
-Resistor box from a crx si.

If someone could help me with this it'd be awesome. I've been up late every night for a few weeks trying to find every detail on my own but I just can't get some of it down.
-Is the PR4 the ECU I need to get my motor swapped?
-What do I need to make my OBD2 motor OBD1? Can I send the OBD2 harness to hasport and they do it for me?
-What year Integra do I need to get the hubs and axles/halfshaft from? What all do I need besides that?
-When I'm doing that MPFI swap how do I go about that with the LS motor? I figure I don't need to depin my stock ecu seeing as I'll have a new one but what do I do about the resistor box and stuff?


If anyone can please help without being all over my *** for not knowing everything it'd be great. I'm really trying to do everything I can by myself but I'm having some friends help just incase and I'll have my laptop by my side just incase I need to look something up.


Thanks,
Jake

 

I JUST SWAPPED A OBD0 B16 INTO MY REX (DX). I HAD TO GET MOTOR MOUNTS, SHIFT LINKAGE, CONVERT DPFI TO MPFI. ALSO YOU CAN USE THE DX HUBS BUT YOU NEED TO GET 90-93 INTEGRA AXLES SO THEY DONT BIND UP. AS FOR YOUR WIRING YOU MIGHT NEED TO GET A HARNESS CONVERT OBD2 TO OBD0 OR VISE VERSA. YOU CAN USE THE CRX RADIATOR JUST HAVE TO GET I BELIEVE A 93 GSR UPPER HOSE. I KNOW I HAD TO USE A INJECTOR RESISTOR BOX CUZ OF THE MPFI. LET ME KNOW IF YOU HAVE ANYMORE QUESTIONS. HOPE THAT HELPS.

 

I'm going to run the motor OBD1. Do I have to send my stock harness to hasport or the OBD2 one that came with the motor?

 

I BELIEVE FOR THAT APP YOU HAVE TO GET A SUBHARNESS NOT REALLY SURE THOUGH
