need help how to i perform this conversion kinda confused i have a b16a motor all stock beside cold air, headers and exhaust plz help thanks

 

From my post in the Nor Cal Forum... This was for Ca state Ref, but should work for you...


Yup, the motor is out of a 89 CRX SIR from Japan. The motor needs to be converted to the same OBD as the car it came in, in the US (1994 DelSol VTEC). My head is stamped 89, and my block say's B16A.



What I had to do to pass...

USDM P30-A00 ECU.

ECU jumper harness *Depending on REF, Some don't like them.*

OBD-1 Dizzy *B16 or GSR*

Dizzy jumper for obd-0 to obd-1.

OBD-1 Throttle body. * I passed with a 95 GSR TB, But the nipple for the Charchol canister bent to the left instead of bending straight up. Throttle cable was rigged. Needs MAP sensor*.

4-Wire 02 sensor in the Exhaust manifold.

Exhaust manifold for a DOHC VTEC motor, if it's aftermarket, make sure the CARB #'s match a DelSol DOHC VTEC, and has the bung for the 02 sensor.

CARB Legal Skunk2 Intake Manifold, or stock DelSol VTEC manifold. I passed with a first gen Skunk2.

EVAP purge control solenoid. From 92-95 civic/delsol.

OBD-1 Thermostat housing w/ temp sensor *Again depending on REF* Installed on my engine when I passed.

Electric VSS *Again depending on REF* Had the stock cable VSS, and I passed...

DATA LINK CONNECTOR *Again depending on REF* Did not have this, and I still passed...


AND LAST BUT NOT LEAST....


A GOOD CAT, I used a 00 Civic SI cat, and used a bung plug from my STI downpipe for a wide band 02 sensor.( because obd-2 cars have 2 02 sensors)

I hope this helps,

Alex

 

^^ I have no idea how telling a person how to pass Cali e-check pertains to the OP wanting to know how to convert to obd1 but here is the answer for the OP:

You will need the following:
obd0 - obd1 ECU conversion harness
obd0 - obd1 distributor conversion
obd1 b16 distributor (93 + Del Sol VTEC or from www.rywire.com)
4 wire o2 sensor

 

research is the key google it
