Yeah, just the temp sensors. Some model highports came with different style tps sensors and distributors. If yours came with the right model distributor meaning non b14 style distributor then use it as long as the plug is uncut. If it is then swap it. You dont need to swap intake manifolds either unless you have emissions testing or they look for it. You can leave your egr temp sensor and egr valve solenoid plugged in and it wont trigger a code on a b13. Unless you get a california emissions equipped car which will have a pickier ecu then you wont get a check engine light for anything. In mine I have had all that stuff off and unplugged since i got the car and first put a jdm motor in and have no check engine light or codes. B13's are not very picky like i said unless you get one that had cali emissions. Those are the ones you have to have the o2 sensor plugged in, egr crap plugged in, knock sensor plugged in.

So decide what you want to do and go from there. As far as for it to run right and sensors, the coolant temp sensors are the only ones to swap. Done. And tps if yours didnt have the correct one or was damaged.

I've read up on previous JDM swaps and everybody says to switch over all sensors. However there really isn't any commentary on equipment that might be usable.

Sensors I definitely want to swap over: Temp sensors, tps, distributor/sensors.

THere is some hardware that I wonder if it must also be swapped. Idle air control unit(A.A.C Valve, F.I.C.D Solenoid Valve), air regulator that is under the intake manifold, and the knock sensor.

My new JDM DE also comes with a bosch oxygen sensor. It looks very much like the USDM fat O2 sensor (three wires black, red, white). I looked at the numbers on the unit and it does share some digits with the O2 sensor on my 94 USDM lowport. The exhaust manifold also looks very similar to the USDM piece.

So if anybody has used the JDM idle air control unit, the knock sensor, the air regulator, or the JDM oxygen sensor please let me know. I appreciate any info that you can provide.


i have the same sr20 in my b13 "95 high port Jdm de", just basically like Ashton said reuse your old intake manifold, the two temp sensors or your temp gauge wont work correctly, the 95 engine uses b14 like stuff so you have to change over your old distributor cause the jdm one uses a different sucket to connect to the harness and also dont forget to swap over the ignitor module to your new de or your engine wont start lol. also since your engine its a 95 make a note to start using 1995 200sx se-r oil filter, a 91-93 wont fit.

Well I just went ahead and changed the temp sensors. Bolted up the US distributor, TPS, transistor, and coil. I swapped the IACV air regulator. The JDM unit is marked 75 ohm the USDM unit is marked 70 ohm. The FSM states the resistance should be between 70-80 ohm. Just for sake of not having to switch it while the engine is in the car I went ahead and put a USDM air regulator on there. The idle control valves I'm going to leave in place and see what happens. Also the O2 sensor I will leave in place. Going from the info that has presented though I don't anticipate any problems with the sensors and hardware I decided to leave on the engine.
