Hey well this guy is gonna sell me this nice motor its outta a 4door integra its a GSR.....now he is giving me the intire swap for a very good deal now i was wondering what needs to be done to put it in my car what i need as far as i know all i think i need is B series mounts for my car and my Civic is a 98 CX hatchback im pretty sure its and OBDOII and the GSR is so do i need an ECU or not and just let me know please if i need anything else to swap it and the site to get those things thanks

 

You need the ECU from the GSR. What year is the GSR?

 

you'll have to run a vtec wire, crank angle (maybe)..

 

well i pretty sure its a 98 the vin says DB8 if that helps at all i know its OBOII and it came stock in that integra and he is giving me the ECU outta the integra also.....and whats with wiring the V-tec wire do you mean ground it and whats the crank angle

All DB8 tells us is its a 4 door GS-R from '94 - '01. You will need to run 2 wires plus a ground for vtec. You will also need mounts from a '99 - '00 Civic Si, except for the top transmission bracket which can be reused from the CX provided its a manual tranny. You will need the GS-R ecu as well. You shouldn't have to wire the crank angle sensor as the civic already has one.

well my car is a 5spd and ok i will have to hunt down the mounts outta an si which ones do i need to make this GSR swap happen with out problems i getting the entire swap from a 4 dr teg and i mean everything mounts,ecu,tranny but i need a new clutch while its outta the car, and thats it i just need a list of what exactly i need to finish and have it runnin in my car

 

Assuming that the GS-R is a 98, which would make it OBD2A:

Mounts
- Drivers side timing belt mount -&gt; '99 - '00 Si
- Rear T/L bracket -&gt; '99 - '00 Si
- Upper transmission bracket -&gt; reuse CX bracket
- Torque mounts -&gt; use the bracket half of the mounts from the integra and the rubber mount part from the civic, or buy '99 - '00 civic torque mounts. (Don't expect to find any '99 - '00 Si mounts in a junkyard btw unless you get really lucky, you'll probably have to buy them new from honda or find a used set in the marketplace.)

Axles
- '94 - '01 integra axles, any model except JDM ITR.

ECU
- OBD2A P72 GS-R ECU
- OBD1 P72
- OBD1 Chipped P28 or P30

Harness
- Reuse CX harness and add vtec wiring, add IAB wiring if desired, preform IACV fix, cut and lengthen connectors as necessary
- Use a '96 - '98 EX 5 speed harness and add IAB wiring if desired, cut an lengthen connectors as necessary.

Vtec wiring



It it ends up being an OBD1 GS-R then follow this for your wiring/ECU, above info for mounts still applies.

- '96 - '98 EX Manual harness.

- Injectors, you have 2 options:
-Option 1 - Cut the injector clips/plugs off and solder on OBD1 versions
-Option 2 - Get a set of used OBD2 B18 injectors. (I perfer this personally)

- Distributor You have 3 options:
-Option 1 - OBD2A B-series GS-R/B16/ITR distributor.
-Option 2 - OBD1 GS-R distributor case, shaft and bearing assembly, coil and igniter with OBD2A CYP/CKP/TDC sensors from any civic/integra OBD2A distributor.
-Option 3 OBD2A to OBD1 distributor adapter harness.

- Alternator 3, possibly 4 options:
-Option 1 - Use an OBD2 B-series alternator
-Option 2 - Swap an OBD2 voltage regulator into the OBD1 B-series distributor (the voltage regulator can be taken from an OBD2 D-series alternator.
-Option 3 Cut and splice an OBD1 Plug onto your engine harness. (I really don't like this method)
-Possible 4th option, OBD2 to OBD1 alternator conversion harness (I'm just not positive they exist)

- ECU Options:
-JDM OBD2A P72 ECU (USDM ECUs will look for sensors that will be missing
-Jumper harness + OBD1 P72 ECU
-Jumper harness + OBD1 Chipped P28 or P30

you can get innovative/hasport mounts or you can use your mounts and get a civic si rear bracket. i would just get aftermarket cuz its easier.

 

Thanks very much everyone who posted on this post you were a lot of help whenever i get my car done i will definately figure out how to post pics on here and i will show you how it all came out and maybe a link to a vid of it l8r guys
