ok i need a parts list for a GSR swap. 94 OBDI JDM GSR motor. comes complete with throttle body, intake mani, rail, injectors, only thing missing is the header.

now the question...i have a 91 EF SI....if i swap the gsr in...my friend has a JDM obd0 ECU for a b16 i believe....can i run the stock SI harness and just get the rywire subharness for the 02, dizzy, vtec...and whatever i might need...any additional plugs let me know. i need to add vtec, knock correct? just run a long wire to the ECU and pin it in. what injectors would i run? do i need to switch the plugs for the injectors or no? i wouldn't need the conversion harness for the ECU right? would that ECU run my GSR?

i know i need shift linkage, mounts, what else do i need? o yea i'll be looking for a
ls or GSR cable tranny.
need help so i can purchase that motor....thanks. i have the GSR harness for it as well

ok ECU is a pr3 vtec ECU
i reaad that if i run that i won't be able to open up secondary butterfly in my stock intake mani...

so best thing is to run a obdI p72? so all i need is go to rywire and get the jumper harness as well as the other subharness and extra wires going to vtec...does the p72 use one o2 or two? help thanks

It has two O2sensors and i have a P72 for sale $150.

 

i'll def let u know if i need it ^^

so i would need to drill into the exhaust for 2nd 02?

also would the p72 run the JDM motor ok? not sure if there is a difference btwn USDM and JDM ECU....

 

I have a stock usdm itr exhaust manifold that you can use until u can find a replacement...or u can have it for $50...

u can run either injectors...obd0 with resistor box, obd1 without...

 

JDM motor does not have the vtec oil switch...if i get the rywire it comes with a connector...is it ok to just not use that?

 

anyone know?
im gonna try to run the SI harness and the rywire conversion kit...convert to obdI....with a p72 ecu on obdo injectors

 

Just tell me your setup when your done, and ill make a harness to your needs

 

Just remember: running OBD0 ecu use OBD0 distributor OR running OBD1 ecu use OBD1 distributor.
Since you can get OBD0 B16ecu you can just change the intake manifold to like BLOX or Skunk 2 so you can eliminate the 2nd butterfly + give you a little more HP.
One more thing. Since EF running one wire O2 same as the OBD0 PR3 ecu.

 

wrong,

obd0 pr3 looks for 2 single wire o2's

 

so no matter what i'm gonna have to drill a hole into my exhaust right?

this is for a shop car....i work at a shop but not a motor swap shop...haha...but i just want to know how to do it so my boss knows whats up...we're a regular repair shop but we're doing it for a friend of his. all the mechanics should have no problem with wiring or anything or better yet custom everything but we just need to make sure we have everything is there when we do the swap...just so we have the other rack clear in a day so we can take other cars in for other service

 

ok lets say i run the pr3 ecu....my stock SI arness plugs right up to the ECU..BUT ill have to run aftermarket intake mani and not the stock GSR. for dizzy i'll have to run the OBD0 one? will the d16a6 dizzy work with the JDM gsr motor? or can i use the GSR one which is obdI but the ECU wont be correct?

 

droppedcrxsi is right, there are 2 single wire O2 sensor in OBD0 PR3 ecu. In the pass I have bridge 2 O2 sensor wires by the ecu and they work just fine.
If you use OBD0 PR3 ecu the stock Si ecu harness will plug right in. And you don't have to buy ecu convertion harness(Save $125~175), but you have to buy OBD0 B16A distirbutor which you can get one from Hmotoronline for about $150, and it will plug right into your Si harness as well, which only left wiring needs to hook up like VTEC sensor, VTEC pressure sensor, knock sensor and 2nd. single wire O2 sensor. You don't have to run aftermarket manifold if you don't want to gut it will run better.
But if you use OBD1 P72 ecu you will have to wire up VTEC sensor, VTEC pressure sensor, knock sensor, 4 wires O2 sensor, and change 7 wires distirbutor connector, plus buying the ecu convertion harness...which more wiring mess you have to deal with!
For me it is just an easier to go with OBD0 PR3 ecu then the OBD1 P72/P30. At the end it is still your decision how do you want to process this swap.

 

you are also gonna need 90-93 integra axles+90-93 integra halfshaft or 94-01 gsr axles +94-01 half shaft
You need an integra throttle cable and a new throttle bracket that bolts onto the throttle body that the cable hooks up to any b series other than gsr will work or any d series
I would suggest converting all of your wiring to OBD1 rywire is then man to see. You send him the si harness and the gsr harness and you get back a plug and play masterpiece and since u are from cali i assume your friend is too and the car has to be bar certified. so you need to use original equiptment as far as ecu
You need shift linkage as well.
I would suggest buyin the hasport efb2 kit allowing you to run a hydro tranny which usually are in better shape then the old cable b series. dont buy an ls takes the point out of a swap like that.
I would also suggest an aftermarket Intake mani u may run into some fitment probs with the stock gsr mani plus IABS are retarded.

 

wat headers do i use for the EF?

would a DA LS header fit onto the GSR exhaust mani? or can i use headers from a 94-99?

 

anyone know what header i need to use with a stock exhaust system?

 

99-00 b16a header worked great on my old gsr

 

also if i get innovative mounts instead of a hasport...what linkage can i use?

 

help help help ...need to order parts ASAP

 

any linkage should work innovtive makes linkage so just buy theirs just remember those mounts arent as good. Also the motor might sit a lil different with their mounts
