Hi,guys,what you guys think,i am droping a jdm b18c type r engine in my 92 civic,i want to get some advice.its kind of expensive,so help me out,thanks

 

Get yourself a USDM 97+ ITR engine wire harness and install it on the JDM motor. Then it will plug directly into your car with no wiring. Your 92 civic is special cause it already has all the wires for VTEC in the cars main wire harness. I think you will have to rework the EVAP-Purge solenoid plug to connect to your cars old EVAP-Purge solenoid, but that's it. Plus you will have to zip tie the purge solenoid somewhere under the intake manifold cause there's no spot to bolt it onto.

You can also use a 96+ GSR harness, but you will have to extend a few sensor plugs due to the upside down manifold. You will also need to move a couple wires from the IAB to the EVAP Purge solenoid (i think). Compare Civic & Integra wiring diagrams to be sure...

Either way you will have an extra plug for the VTEC pressure switch that the JDM motors don't have, but that's okay (tuck it away). You will also have two extra plugs at the passenger side shock tower that won't connect to anything, but that's okay cause they are for OBD-2 sensors and you will want to stay with an OBD-1 ECU (tuck them away too)...

For the ECU, don't use the one that comes with the swap (sell it). Either get yourself a chipped USDM P28, or if you can afford the down-time, simply send in your stock ECU and have it reworked for the ITR motor. It's not expensive and will work WAY better than changing over to OBD-2. Then you will have no worries about the immobilizer, crank-sensor, knock sensor, adding wires, etc... Kenji Plennert (here on Honda-Tech) or Phearable.net are two of the best places to get chipping and whole ECUs.

BTW: Make sure the ECU company knows it's a JDM spec ITR motor so they can bypass the VTEC pressure switch inside the ECU. This will save you wiring problems later on. Also tell them what octane your premium gas is in your area so they can adjust the timing maps...

This is the setup I have in my 94 CX and it rocks. I only had to add 1 wire for VTEC solenoid cause 93-95 Civic main harnesses are not pre-wired like yours. Good old cost cutting...

do i need to change the fuel pump and the civic axel nut is 32 mm,is the type r axel more bigger

 

fuel pump is the same, so no worries.

As long as your swap is 96-97 JDM ITR, the axles will fit perfectly. The axle nut is the same as well. You should replace them every time you take them off. Autozone sells them for cheap.

If your ITR swap is 98+, the axles won't work in your car. The 98+ JDM ITR axles have a larger prelude spline section. You would have to get some US Integra axles instead. This is one of the big reasons I went with the 96-97 ITR swap...

BTW: Even with the upgrade parts, the 98-spec JDM ITR wasn't any faster/quicker than the 96-97...

 

thanks,how is h22a compare to b18c

 

H22 = More torque & weight, but less rpm. Same power overall. More power potential if you have deep pockets. Transmission sucks. Doesn't bolt directly in and requires EGR system to be legal swap. I wouldn't bother. H2B swap (H22 motor & b-series transmission) makes it more worth while, but you will still need EGR system...

BTW: If you want to retain AC with your ITR swap, get yourself the CRV P7J AC bracket. They are $60 new and you reuse the integra tensioner. Integra AC bracket won't work for you. For the install you need to leave your AC compressor hooked to the car when you pull the old motor. Then everything will bolt directly together with the CRV AC belt...
