So I broke the right side crossmember bolts on my 4 door at a track day and needed a new car since it was getting too beat up. Found my 10th ED civic today about 1 hour away from where I live for really cheap. A 1991 Cx with a b18a swap, the guy did a clean job swapping exept the engine harness was completely ****ed, all the wires were cut and messed up. The passenger side engine mount is custom and has been done very nicely however the front tranny mount is a piece of metal welded to the subframe and bolted to the tranny. I dont care about the vibrations at idle, but will I have more chances of blowing my transmission or axles since the front mount is solid?

I am also thinking about taking my wiring harness from my 91 4 door, it has a d16z6 in it with an obd1 conversion however I think the harness is the original.
Can I use my obd1 harness on the obd0 b18a? If not what modifications do I have to do? I Have a 93 b18a ecu I can use.

 

cx? do you mean dx? as along as both cars are of the same type stock i don't see why not. when i say this i mean both either came factory DPFI or both came factory MPFI. you can't use a mpfi harness on a dpfi body, the plugs are different. yes you can use an obd1 harness on an obd0 engine, although to convert to obd1 you'll need at bare min. a 4 wire 02, obd1 dizzy and obd1 ecu. i'm assuming you'll want to use the obd1 injectors, which you can use from the z6 on the b18 since they're the same afaik and i have researched it a bit.

 

Thank you for this helpfull information!

 

you dont need a front mount. when you buy aftermarket mounts they dont even come with a front mount.
