i just picked up a 1991 honda civic awd in perfect condition for $300 with clean title. im currently building a poor mans type r that im going to throw in the car. i know it wont be a awd anymore after i do the swap but i think it will still be sick as hell. noone would expect that thing to ripp. its going to be my first build and im just curious of what i need to do to it to make the swap happen. like ecu? if i have to compleatly switch out the wireing harness to work on my obd1 motor? what axles do i have to use, cuz i been hearin people that do motor swaps have problems with axles fallin out or somethin. stock motor is a d16y6

WHAT DO I NEED TO MAKE MY CAR A DRIVER!!!!!!!

so far i got

82mm gsr block
ls crank
crower rods
82mm hi comp pistons
port n polish jdm b16 head with gsr cams
port matched type r intake

 

Did a similar swap on one of my wagons. Pretty much the same as any other B series swap into an EF.
I used my existing DX dpfi wiring harness and OBD1 GSR wiring harness to make the needed wiring harness. First you need to convert to mpfi and then to OBD1. You will also require a OBD-0 to OBD-1 jumper harness. I used a P72 GSR ecu but a P28 sohc vtec ecu will also work since you will require some sort of chipped/programmable ecu for tuning anyway. In addition to the B series motor you already have you will need a B series trans,EF swap specific mounts such as Hasport /Innovative, shortened B series shift linkage and 90-93 Integra axles w/intermediate shaft. Some people have also used 94-95 Integra axles and intermediate shaft. Also 90-93 Integra rear trans mount bracket. Good luck.

 

hey man thanks alot. i also need some help with what size of injectors to use???

 

stock injectors would probably be fine. if you want to play it safe then maybe go with some 330cc units.

and this should answer some of your questions

wouldnt a b20 awd trans work for this platform as well??

 

i want to make this swap as easy as possible if thats possible lol. i dont think im going to keep it a awd. thank you for input and the thread. it helped tons

 

Damn! Those old school AWD trannys were nutts strong bro. The newer B series AWD are weaker than the oldies. I would just do z6 turbo awd. But I built a PMTR engine in my last EF 190hp.
I was happy I ran pr3 pistons ITR cams B16 head I ported/polished, GSR dual intake springs on the Exhaust side and some other goodies

 

No.

Hate seeing people swapping out the awd systems to put in B series. Such a waste.

 

i'm sure there are those that hate you showing off your car.....

each to their own

if you hate, don't post......

bye

 

Why not buy a cheaper and easier to swap front wheel drive chassis? You could probably sell the rt4wd wagon to someone who appreciates it, buy 2 front wheel drive wagons with the profit and have an easier swap on your hands.

Makes no sense.

 

im with sp33. The SOHC awd system is awesome.

 

ok, I'm sorry.

I thought the Op was going to continue with the awd setup.

have now read that he wants to ditch the idea and wants to run FWD setup.

what a waste.

can't hate you for it though, just don't agree with what you're doing.

they are rare as setup the awd Civic (well at least its rare here in AU) so its such a waste.

still can't hate you for it though

lol

 

Did you not read my first response? I was wondering why your reply made no sense.

 

that makes alot of sence to just keep it a awd since there arent many around. i think im just going to do that with this one and get another fwd car for cheap like i did with this one. i mean hell. there are tons of cars out there that are nice and cheap. i got my awd for $300 and its clean as hell.

thanks for knockin some sence in me haha

 

but my idea for this car was to put my b swap in it and make it a totle sleeper car that would be funny to see peoples reaction.

 

B to D adaptor Go to bisimoto.com and give them a holla! The ring gear in the SOHC awd trans is way beefier than the b20's

 

b series does not equal instant awesome-ness as most people seem to suggest.

 

This thread is worthless without pics.

 

I have seen a couple of AWD wagons swapped w/B-series motors and using the AWD trans from the first gen CRVs. Does require some fabrication as the transmission mounts differently to the frame rail.

 

The front and rear differentials also have different ratios, so you'll have to use the CRV rear end, which doesn't mount the same as the wagon rear end. Headache.

I heard the adapter plate doesn't clear the transmission?

 

really? engineering fail. d series ftw
