Ok, this is my first swap for my own car and Im doing it with a few british guys I don't know to well and all they have done is two swaps on honda coupes that were already obd2 and British spec.

Here is the low down -
Car -93 Del Sol
original motor was a D series SOHC 1.5 Non-vtec

New motor B18C6 out of a 99 or 98 UKDM Honda Integra Type R

Motor mounted fine and swiped a del sol B-series shift linkage from a Junkyard - New flywheel and clutch have been installed with a DC sports ceramic header. ECU is an OBD1 p28

The harness is two piece off of the Del Sol and the Integra Type R was two piece also - we used the Del sol piece comming from inside the car and hooked it up to the 2nd piece that connects to the B18. they clipped in perfectly and everything seems to match up.

First start up - runs rough and surges but stays alive
Engine codes - it was Vtec - so we wired up Vtec

No more engine codes and we messed with things abit but now it wont idle on its own - we did mess with they idle though because it was all the way out before. Ive checked the dizzy(new one) every spark plug cable and too see if the plugs were sparking in each cable ... we also pulled each plug to see if maybe one of the cylinders were bad and all reacted the same.
When the plugs were pullede they were covered in black soot. I believe that meant over fueling?

During trouble shooting these are the theories I have and what has been suggested.
1- I used the fuel line from the original motor - Should I use the integra one from the pump to the rail? Are they different sizes?
2- The 02 sensor going into the header was a 2 wire on the d series and a 4 on the Integra - do I need to wire up all 4 wires - would an 02 sensor unhooked make it run this crappy?
3- Was there a difference in the type of injection on these models. Today someone mentioned dual point and multipoint injection and that it might have been different. - I thought this would be taken care of by the Ecu but Im tired and have been working on this all day.- Thier way to fix this was to totaly pull the harness and use both pieces of the integra one and go OBD2 - although I cant do that cause the p73 Ecu has an immobilizer that goes with the Key barrel and I dont have that out of the original donor. The other thing that was suggested was to use a harness converter from OBD2 to OBD1 - But since I have 6 days before the car needs to be shipped to the US and parts here our outrageous, I would really like to avoid that route if possible.

I know I might get a bunch of crap for this post, but I would like some help since Im still learning.

Someone on another forum said I shouldnt run the p28 unless its chipped, does this matter? I thought the p28 came out of the B16 civics??? Shouldnt that run an B18 rihgt?

 

1. The fuel line should be fine is its not collapsed, which it probably isn't.
2.The O2 sensor will make a difference. If you are using your old harness, I would use your old OBD1 O2 sensor.
3. You need an OBD2-OBD1 jumper harness and OBD1 ECU

 

i would switch out the ecu to a p72 gsr ecu and get the jumper harness... boomslang.com

 

you should have used the harness out of the Des Sol, it was already v-tec and obd1, most of the sensors should have plugged up and others you might of had to change, but for the most part everything should have started and ran fine using the factory stuff out of the del sol.

 

Well the harness was obd1 but not wired for vtec..it was a dseries non vtec out of a 93..plus we tried matching everytthing up... the injectors use different plugs so it wouldnt plug straigh in

 

use the injectors out of an OBD1 integra, the v-tec you can wire in manualy into the p-28 and it should work fine with the other sensors hooked up and working properly

 

will injectors out of an obd1 b16 work?

Im pulling a b16 obd1 del sol harness off of a brit del sol same year as mine amd was hoping to use the b16 injectors, harness, throttle body, and alternator
