OK I got a b16a sir II obd1 motor i need to swap in My 92 LS teg but its not vtec so I know I cannot used my harness or the harness that comes with the engine due to the fact its jdm and all backwards. So how can I fix this problem, from what I am reading I need to buy a USDM GSR or civi SI harness. Is that all i need to do?

teg92

just use your stock LS wiring harness and run the vtec wires, my buddy is running a JDM GSR motor in his 92 DA and he used his stock LS harness and just ran the vtec

teg92's suggestion is the cheapest solution. Trying to find a second gen GSR wiring harness for reasonable money will be difficult.

All you need is shielded wire of the right gauge, and the ECU pinout chart.
Are you running the JDM ECU?

djkarlkani

yes, iam runnning a jdm ecu, so how many wires do I need to run and from what senor to what, I hear its only three wires but I have no ideal how to find out what sensors.

teg92

the vtec plug should be near the Distributor, you have to find the right pin out on the ECU before you doing anytthing

djkarlkani

so are those the only wires I need to add to my wiring harness, will all the sensors be covered by my harness.

djkarlkani

ok after doing some reseach I think I understand. All i need to do is run the vtec solenoid, vtec pressure swtich to A4 & D6 of my obd1 ecu. ground the vtec pressure switch to any ground. And last run the Knock sensor to my ecu which is D3.

IF anyone has done this before please let me know is this all i need to do when I drop my b16a sir II into my 92 LS(obd1) integra.

djkarlkani

ok here is what I understand what to do


so my only question is what the heck is the secondary intake soleniod, some ppl dont metion it at all and some ppl like this pic say I need to run this soleniod to my ecu.

teg92

thats looks about right

B18C1 (GS-R) motor has a dual stage manifold, basically two paths for air to go through. By changing over paths at around 5700 rpm, you keep the right intake manifold for low rpm operation and open it up for high rpm operation. It's done by a vacuum operated diaphram controlled by the ECU. If your installing a B16A, you don't need to concern yourself with it, they use a different single path manifold.
