Im doing a JDM B18C GSR swap into a 1999 Civic EX and I wanted to know exactly what extra parts I would have to purchase. Here is what will come with the swap: GSR Motor, trans, ECU, Axles, Shiftlinkage.

Here is what I know I am already going to have to get:

Obd2 to OBD2B wire harness
99-00 SI motor Mounts

What other esential parts am I going to need to get the swap working?.

 

Change the water pump and timing belt while the motors out.

Seems like you got all your bases covered to me.

 

your distributer plugs may not match up. mine didn't, but mine's usdm. if they don't match, you can either buy a 99-00 SI harness, or re-pin your harness with a plug that fits. you might wanna pick up a gsr throttle cable too. i've heard that the stock civic one fits, but i went ahead and got the gsr cable, so i don't know if that's true for our civics. go to a dealership and pick up 3 qts of MTF and grab some oil and a filter. you'll need the gsr's upper and lower radiator hoses too. you can get those at autozone, or whatever auto parts store you want to go to for pretty cheap. and of course you'll need coolant. and you may want to get a new intake.
that's all i can think of right now.

P.S. you CAN run the gsr motor with your EX ecu. i had to do that until i got my jumper harness. it'll run fine, just don't expect it to run like a real gsr.

 

how much do you think SI mounts will cost me at a dealer?.

Prices on there look good, but how do I know exactly what engine mounts on there that I need.

 

Ive got the whole thing laid out on my site. you only need 2 of the Si mounts The rear mount (tranny/motor) and the drivers side upper mount. Use your EX harness and forget about repinning your ecu for the distributor cause you can just match wire colors and solder them in to the plugs from the gsr harness and itll work fine.

I will have to ask my mechanic out the EX harness thing cause he insist that i have to get a 1999 or 2000 motor, or get the OBD2 to OBD2b harness since i have a 1999/2000 series civic

 

where can I get a obd1 to obd2b conversion harness from?

 

actually, now that I think correct me if im wrong but I would basically just need a obd2b to obd1 harness to run A 94 95 swap right?. I heard running a obd2 ECU is better performance wise anyway so I dont care to run a obd2, but what about when emissions time comes around and im suppose to be running obd2b, what will I do?

 

obd1 ecus are better for performance but depending on where you live depends on whats going to happen when emissions come arround. I still havent had to go do an emissions test yet so i dont know. as for the harness I got mine from a place called boomslang fabrication. pretty good quality.

 

ok so what will be a easy way to convert back to OBD2 once its time for emmisions?. Get a OBD2 ECU?, but what about the harness?.
