So i have a total'd 94 integra LS, hit from the side with a working motor, and i also have a 91 integra LS with a blown motor. I want to swap the motor, and also anything else i can from the 94.

So what i'd like to know is the easiest way about doing this? fully swap motor and ecu? keep the old ecu some how? what wiring would need done? Does it just bolt right in or do i need the cross member from the DC? Which axles would i use? Also, what else can i take from the DC teg, brakes and rotors? suspension?

I know this could probably all be searched, but there is just so much to search through, im hoping not to get flamed too bad just asking the questions, since there are a lot of knowledgable people on here.

Thanks.

 

Well with all the time you have waited, you could have had your answer within 2 mins. Its a direct swap. Motor only. Keep the obd0 intake mani, dizzy, etc... Just swap engines only.

 

cool thanks. what about other stuff like brakes + rotors, suspension?

 

brakes and rotors are the same. no need to swap them, but keep the calipers as spares. if the 94 has adjustable coilovers, you can take those.

the 94 intake manifold flows better and is still equipped with a fitv, so i'd leave it on the engine when you swap. the only modification that needs to be done is to extend the coolant temperature switch wires. the switch is located on the back of the block on your 91. it's got a big rubber boot. 2 wires. on the 94, the switch is located on the thermostat housing.

when you pull the motor, pull the transmission and motor out the bottom as a unit. then separate them out of the vehicle. that's the easiest way

 

Also has to extend the map sensor wires if hes keepin the 94 tb. And as for the temperature switch wires, its easier to just open up the loom and pull it out, then retape with electrical tape. I did it and it looks oem.

 

Don't need to extend the map sensor if keeping the 94 throttle body. Just unplug the one from the firewall and put the same plug onto the TB.

 

The map sensor is by the MC.... Has to be extended to reach the opposite side of the engine bay..

 

don't forget u might have to change the post mount too. cause the da mounts have a different bolt line up. idk i had to do that wen i put the b18b in my da also u can keep the obd1 alternator

 

If you wanna keep the obd0 you have to swap the water tube, the pulley, and the intake manifold. Other than that.. Its straight bolt in... Ohhh and the passenger mount thing has to be swaped

 

that was i was saying i think its called the post bracket it bolts to the block i think right?

 

yeah that muthafukka. lmao.

 

so apparently theres 2 ways, keep obd0 or convert fully to obd1... as far as i can tell, going to obd1 all i have to do is extend the temp and map sensor? do i still use the 91 tegs ecu? also are the tranny's the same? can i just swap the whole motor/tranny or should i just keep the 91's in there?

 

Tranny wont work from the 94 unless you get the innovative or hasport hydro tranny conversion. And you are going to need an obd1 jumper harness to run the obd1 ecu, 4 wire o2 sensor, etc...

Obd0 is easier cuz its a direct swap for the longblock, but the full obd1 engine wit matchin intake mani, ecu, etc.. will run better.

 

what do you mean by obd1 jumper harness?

 

It converts the obd0 plugs for the ecu, to obd1 cuz the onbd1 ecu dont bolt straight up. Google obd0-obd1 conversion and youll get all your info for the swap.

 

just keep it simple. swap the motor. extend the map sensor wiring. call er done
you won't gain anything by obd1. unless you wanna mod this thing relatively in the future
