hey guy i just recently bought a obd1 motor but my car is a 97 ek hatch obd2, how or wat can i do to make it all ether obd1 or obd2!!!!! is their any write up on how to convert the harness??

 

You know adding info that actually pertains to the question being asked will get you more help than some generic "got a question!" topic title.

First thing we need to know:

Does your car need to remain OBD2 for state emissions?

 

Second thing we need to know:

What motor did you buy?

 

my bad about the emission wat ever is easier thats wat i wanna do, and the motor is a b16a block, with gsr head, and tranny!! and its obd1

 

You need the following from a 99-00 Civic Si or 96-01 Integra:

Distributor
Injectors

From there you can also add an alternator from one of those vehicles, or take your SOHC alternator apart and swap the voltage regulator (where the engine harness plug into the alt.) into the OBD1 B series alternator.

You will need to do the CKF bypass trick seen BY CLICKING HERE

You'll also want to run an OBD2 ECU from any 96-97 Del Sol VTEC, or buy a jumper harness and run the OBD2B 99-00 Civic Si ECU - this is all to stay OBD2 compliant and pass emissions.

 

Oh yeah we need to know what kind of car this swap came from!

If it came out of a 92-95 Civic then you'll need to change almost all of the engine mounting brackets and mounts too.

 

oh ok koo,it came of an integra 95!! thanx any more info!!

 

Okay you'll also need from a 99-00 Civic Si:

Timing side engine mount bracket that bolts to the block
Use your stock 97 Civic timing side mount itself

Rear tranny t-bracket
Use your stock rea rmount itself

Topside tranny mount - any 96-00 Civic 5-speed, SOHC or DOHC Si

Front tranny steel bracket (three bolts) - 99-00 Si or possibly the current 94-01 Integra

Right front anti-roll mount/horseshoe mount - use your stock one

A/C bracket - if keeping A/C use CR-V or Del Sol VTEC bracket; no A/C or P/S = current Integra bracket

Left front anti-roll mount - stock Civic
