USDM GSR wiring harness (its LHD) (Mine was ODB1)

GSR upper and lower Radiator hoses
GSR Throttle cable
GSR Heater core hose

A a lil bit longer Fuel return line.

Now this is all I needed to buy to put it in a EG civic.

You will also need to wire in a knock sensor, and Switch A17 to A20 on the ECU pinout.

you MIGHT need some exhaust work as well where the header meets the cat.

Also you need to get new wires/plugs/cap/rotor

I know all this because I just finished my swap on Saturday.

P.S. And I got my swap from HMO as well best damn clean engine I have ever seen

t bracket. if its a 96 or up, then you will need a 00 civic si t bracket. also,you might need to convert your iacv from 3 wire to 2 wire plug,if needed.

thanks for the good info. someone told me i cant use a gsr engine harness in a 96-00 civic , is this true ?

Unseen Racer

you can use it. if you get the GSR harness, get the interior harness aswell
(the one that the harness itself plugs into and that one plugs into the ECU. pretty much the middle piece between the ECU and the engine harness)
you will also want to get the GSR ecu

thanks for the replies

im 99% sure you cant use the integra harness because its a 2 peice and the 96-00 is 1 peice, your civic harness is bascily plug and play with the b18 because you have vtec.
you may need a jumper cable for the ecu.
