I have a 95 Del Sol and want to swap in a gsr, its from a 97 JDM auto car and the previous owner kinda hacked up the harness can i use the z6 engine harness
i am planning on disabeling the butterflys and am going to run a p28 ecu tuned with crome. Can i use this harness?

 

Yeah, you'll just have to add the knock sensor wiring.

Edit, if your using a P28 you don't have to do anything, just use the Z6 harness.

 

the injector plugs are different can i just swap them over.

Yeah, sorry, i forgot that the engine was OBD2, either swap the injectors or the plugs, swap the alternator for an OBD1 B-series unit, or swap the voltage regulator out of the D-series alternator and put it in the B-series alternator. and you'll have to either swap the distributor, or swap the plugs/get a conversion harness.

 

Ok i got a distributer MSD one as well as the injectors (are they the same) from an LS and a LS alternator, am i good to go.

Alternator and injectors will be fine, distributor i'm not so sure of, I can't remember if B-series vtec and non-vtec distributors are the same, if they are different its just the mounting flange which you can either grind to fit or swap the guts into a vtec distributor case.

 

you may have some issues with the tranny.
Easiest way is to go ahead and aquire a manual transmission.

when i say issues, i mean clearence wise.

 

An LS dizzy will not work - not the same part at all.

You can easily rewire the OBD2 dizzy to be OBD1.

I made these crude pics years ago when I converted a B16A2 OBD2 dizzy to an OBD1 style 2 plug style:









Basically you can cut the two pin plug off of an old OBD1 dizzy, unpin the two fat wires from the OBD2 dizzy, then solder the same color wires to the plug you cut off, as seen in pics.

To the the OP, yeah if your dropping in an automatic transmisssion, don't. I'm not sure how bad the clearance is on a del sol, but on a 6th gen it doesn't really fit, like you have to cut the frame kind of doesn't fit (i just learned that today), and then theres the TCM you have to wire up, mounts you may have to fabricate. Its just not worth it.

 

BTW:

You can't use the auto tranny without cutting/fabbing for new mounts, so get a manual tranny. I know from 1st-hand experience, and it's a freaking nightmare.

Also if you want to do literally ZERO wiring changes find yourself any 96-01 Integra GS-R/ITR engine harness and simply plug it into your Del Sol's underhood chassis harnesses at each shock tower:







I run this exact set-up in my own 1992 Civic with 98 spec USDM ITR swap, with the 98 ITR engine harness, and a P28 ECU. It was literally 100% plug and play. It can be for your Del Sol too.

How is it different, i'm not disagreeing with you at all in that it is different. But is it the case/mounting flange or are the sensors/coil different between the LS and vtec distributors?

Different mounting ears entirely.

I'll find pics.

 

Integra LS, non-VTEC dizzy:



B series VTEC dizzy:

 

Ahh, I see. I figured the mounting flanges were different, they're more different than i would have thought though. I figured it would be close enough to hack the mounting flange up (not my prefered way to do things, but i know sometimes people get things cheap and like to make them work)

 

OK i should have been a little clearer i will be ueseng a 97 GSR engine that was from an auto car but i have a standard to go with it i also have an obd-1 MSD distributer can i use the z6 harness without very many issues, if there are any what are they. Can LS injectors be used or the z6 ones.

You can use the Z6 harness, you may need to change the odd connector, i can't think of anything off the top of my head, you've taken care of the major stuff (alternator injectors distributor) yes you can use the LS injectors, just not the distributor as B18C5-EH stated.

 

Another issue i just came across where does the gsr get the signal that it has proper oil pressure for vtec engagment the z6 gets it from just below the vtec solenoid, on the heads the pieces comes off where the sensor screws into but on the gsr piece it has a casting for it but it isen't tapped out can i just tap it out and screw inthe pressure switch from the z6.

 

You can swap the VTEC solenoid from the Z6 onto the JDM B18C, or piggy back he VTEC signal wire with another wire via scotch lock and run that piggy backed wire into the VTEC oil pressure pin location at the ECU.

 

the solenoids are the same but that still dosen't let me use a pressure sensor.
I have pics but do not know how to post em.

 

OBD2 JDM engines don't have a pressure switch, B18C5-EH2 stated this, but if you connect the wire going to the non-existant pressure switch to the vtec solenoid wire vtec will work. But shame on you B18C5-EH2 for suggesting a scotch lock, i wouldn't wish those things on my worst enemy. quick as they are the wire tends to corrrode inside and or break where the scotch lock cuts into it.

 

so on the z6 harness that i am useing just connect the wire from the pressure switch plug and wire it onto the wire from the vtec solenoid.

 

yes

 

There are two wires in the pressure switch plug wire them together to the vtec solenoid???

If I assume he has a soldering gun and knows how to use it I'd suggest soldering, but honestly I see the scotchlock technique as being cheaper, easier, and much quicker.

While I agree that scotch locks are quick and dirty, the OP lives in newfoundland, if its anything like new brunswick, which i'm quite sure it is. The road salt will rot that connection in 6 months, no exageration either. Even good pera-seal butt connectors with the built in shrink tubing and glue will turn green around here, I don't know how thats even possible but i've seen it happen. If it was california then yeah scotch locks are fine for this sort of thing though.
