im planning to swap in a jdm b16 into a 2000 si coupe will everthing plug in or do i have to make changes. i already have obd2 to obd1 jumbers is that all i need..

 

What year is the B16 from? Is it OBD2b???

 

Reading owns you....hint hint "look at the title"

 

I would just run it as obd2b

 

You have to use your obd2 injectors and your engine harness.

 

2nd gen B16 swap is pretty simple, with the exception of the crank angle sensr built in down by the crank. Either you have to swap oil pumps, or buy a new usdm obdII style....

or, ou can do the OBD1 conversion as you mentioned, needing only an ecu and harness

 

JDM ans USDM have many differences including on top of the OBD2b to obd1.
-IAT sensor is located on opposite side of engine.
-IBD2 may have 2 IAT sensors vs. 1 on the OBD1. OBD1 ECU will only look for one.
-Dizzy is 2plug vs 1plug.
-2 02 sensors Vs. 1.
-O2 sensor plug will need to be extended
-Map sensor is on the Firewall/fuelfilter bracket vs on the engine.

Could be more just what ive found on my own build already and im not even done yet. Running but with a check engine light.

 

None of this really matters......the OP already has a B16, and can swap over parts he already has!!!

 

Yeah do you have the old b16 from the car? If so swap over the intake (including the injectors) and exhaust manifolds. Swap alternator and distributor over. Bypass the CKF. Call it a day.
