what exactly will i need to do this swap, any tips or info would be appreciated. thanks

 

Check the FAQs section.

There are plenty of write ups about swapping a b-series into a EF. Its all the same whether it came out of an RS,LS or GS, its still a b18a1.

Good luck!

 

You really need to take a look in the "CRX & Civic FAQ's" or just use the "Search" button. But here you go:

I will need new motor mounts right? what ones

 

All 4 (or 3 in some kits)

 

will the ones from the integra fit? are all mounts the same? will i need mounts for a b18a1 or will stock ones do.

 

No, stock mounts will not work. you need aftermarket mounts, Avid, Innovative, Hasport, and many others. You should really look at the FAQ's thread, all these question can be answered in there.

I know this thread is old but I have a 92 Integra donor car that I am going to swap a lot of stuff from it to my 91 LX sedan. I thought this would be a good place to add some info.

I haven't seen a lot of info about going from OBD0 to OBD1. I understand that I have to add wires for the injectors and distributor. Do I need to convert anything else to allow for the OBD1? Should I use the EF or DA harness? And....Will the ecu from the 92 automatic transmission integra work on my swap with a 5 speed?

 

Dude, seriously, SEARCH.

Everything that has been asked in this thread has been covered MANY times.

 

This is all assuming you are using an 88-91 CRX/Civic Si or Civic EX engine harness. If you have a DX/LX/STD model you MUST first convert DPFI to MPFI.

-injectors: delete resistor box and use the Integra injectors, solder on OBD1 connectors or alternatively use 88-91 CRX/Civic Si or 90-91 Integra injectors and leave the resistor box

-distributor: rewire the engine harness to OBD1 plugs or use an OBD0-1 adapter harness, OBD1 distributor must be used on OBD1 ECU, OBD0 and OBD1 ECU and distributor can not be mixed

-Sensors:
1. add 3 wires to the ECU for the primary O2 sensor (ground, 2 heater wires)
2. most OBD0 have the fan switch on the back of the block, you'll have to wire the wiring to your thermostat location of the OBD1 engine
3. most OBD1 have the MAP sensor located on top of the throttle body (excludes 92-93 Integra) while the MAP is on the firewall of OBD0, you can use either location
4. EVAP purge will have to be manually added on OBD0 if you plan on using it
5. The following should be plug and play: IAT, IACV, ECT, plug for gauge temp
6. If installing a VTEC engine you'll need to wire up manually VTEC solenoid, VTEC pressure switch and knock sensor (excluding SOHC VTEC models)

ECU: OBD0-1 adapter harness


To answer your question you can't just plug and play the Integra wiring harness to your harness.

 

Yeaaaahh. Sooooo. Once I narrowed my searches to the different items rather than the whole swap, it helped a lot. One thing I was wondering is since mine is an LX with power steering, will I have a lot of trouble using the power steering. Or should I get a manual rack and delete the power steering. I dont really care if I have it or not.
