honda-tech.com/.../92-00-honda-engine-swap-wiring-guide-vtec-non-vt... Oct 8, 2011 - 92-00 Swap Wiring Guide for VTEC and Non-VTEC ... try to compile one thread that would try to answer pretty much 95% of all questions ... I wanted to do this because often times I end up posting the same thing to ... to ECU harness so using an EX/SI 92-95 engine harness will make VTEC plug and play.
no, you will need to swap all the sensors and wiring harness from your old engine, you must have gotten a different year engine from the salvage, when swapping engine or transmissionsal wise use your original sensors and wiring.
The 96-98 Civic EX came with an OBD2A D16Y8 engine. That is the only engine that will go in as a direct replacement with your current engine ECU. It's an SOHC VTEC engine that has two extra connections not found on the other 96-98 Civic engines - a VTEC solenoid and a special oil sensor used to determine if VTEC engagement is possible. If you swap in an older Civic engine (92-95 generation) you'll have to convert the car to OBD1 (requires a special adapter hardness) and run the ECU that goes with whatever engine you use. This will break functionality of your OBD2 diagnostics port, and depending on which state you live in will cause you to fail emissions checks. If you install a D16Y8 engine from a 99-00 Civic EX, you will have to swap the intake and exhaust manifolds from your old engine to the new engine, and you will be able to continue to run your existing OBD2A wiring and ECU. The 99-00 Civic EX engines have additional sensors, since those engines are OBD2B. The easiest fix would be to find a SOHC VTEC D16Y8 from a 96-98 Civic EX, as it would be a direct plug and play replacement.
More than likely its your temp sensor on the front of the engine, Ive seen it be the cause of things similar including high idle when car first starts(happened to me when I switched out my 1.5 for 1.6 sohc vtec engine, engine was built as an automatic so i changed out the flywheel etc but no place for the sensor) and happens to be the sensor for my radiator at the same time so it controls the fan.
Anything that is OBD 1 or newer if you want it to be legal, here are the most common options and the basic requirements. 1. B16A2/3: Completely bolt-in Swap, VTEC needs to be wired, SIR II, Hasport shift linkage. Del Sol VTEC for the del sol 2. B18B: Completely bolt-in swap, SIR II, Hasport shift linkage. Del Sol VTEC for the del sol 3. B17A: Completely bolt-in swap, cable-hydro transmission kit(not recommended) or hydraulic b-series transmission, VTEC needs to be wired. 4. B18C1: Completely bolt-in swap, VTEC needs to be wired. 5. B18C5: Completely bolt-in swap, OBD conversion, VTEC needs to be wired. 6. B16B: Completely bolt-in swap, OBD conversion, VTEC needs to be wired. 7. H22A: Mount kit required, Hasport shift linkage, VTEC needs to be wired. 8. B16A: Not recommended! Too much work, more costly compared to B16A2/3's. 9. D16Z6: Completely bolt in, VTEC needs to be wired. 10. D16Y8: Completely bolt in, VTEC needs to be wired.
