Got a 95 si hatch and want to swap a gsr motor. Im sure its been asked many times but did a search and didnt come up with what I was looking for. I need to know everything that I will need to complete this. So far im hearing it almost direct drop in and bolt up except for the harness. But key me in on what shift linkage I need, what ECU I need, will I need gsr axles?, and what harness I need and so on. Oh and are the gsr motors OBD1? Thanks.

 

The 94 and 95 gsr is obd1. Youll have to use a GSR ecu because they have a dual stage intake runner system. Youll have to use the 94-01 Integra shift linkage. I would just use your harness and make it fit(change some plugs and lengthen possibly).
Oh and youll want to use a 94 to 95 GSR OBD 1 ECU. The axles you will most likely just use gsrs. If im wrong someone correct me.

 

use your Si harness and just transfer it over to the GSR motor
you will need:
B series motor mounts
B series shift linkage
B series rear tranny mount bracket
GSR throttle cable with firewall support bracket
GSR axles and half shaft
obd1 GSR ecu
wouldnt hurt to upgrade to a dual core radiator, or a teg radiator.
also need to add a couple wires to your ecu plug
only wire you will need to lengthen will be the O2 Sensor wire.

 

All right thanks guys. One more question though. Of the extras that you listed how much do you think I can get all that stuff for if I shop around?
