OBDI Swap

I was looking for a harness to convert over to OBDI. I came across this page but am not sure which is the proper one.

http://www.evasivemotorsports.com/me...FQqNHgodpjsojQ

I was thinking the second or third one but then the one's lower down talk about using a VAFC and what not, so I'm not sure which would be appropriate.

Re: OBDI Swap

If i do this swap, will I still be able to pass inspection? My teacher said that any car after 95 won't pass with an OBD1 if it came with OBD2.

Re: OBDI Swap

its obd2 all 5th gens are obd2 ... and no if you convert to obd1 you will not pass a emissions inspection. these emission inspection are in the metropolitan areas. other states mostly only do safety inspections. if you know a "special shop" and have someone w/ a stock prelude or ...obd2 prelude... you might be able to use that to help you if you get what i mean.

I hope your not talking about me, because as far as I know I barely post at all accept on the few threads I started to acquire some info on something I'm in the process of doing. If this forum frowns upon answering my questions and helping me out with my car then just let me know.

P.S. if anyone reads this, please read a few posts ahead because I still need an answer to that question... if that's allowed.

Re: OBDI Swap

It has less restrictions in the system as well, which I guess is the reason for the easier tunability.

the main components that you need to swap when going from OBD2-1 are ECU, injectors, and dizzy.

Re: OBDI Swap

okay sorry ive been busy ...
to make a car obd2 to obd1
... now if you have an obd2 block.... and obd2 wire harness
just the step down harness will make obd2 to obd1.

now in my case.... i have an obd2 car... w/ obd1 motor and obd1 ecu.
i had to change the distributor to obd1 from either the h23 or h22. the reason being is the crank position sensor and another sensor i can think of right now were built into the obd1 distributor on obd1 motors not available which arent in the obd2 distributor. i had to rewire the four wires from the obd1 distributor to the ecu. otherwise my car wouldnt start. since it wouldnt see these sensors.

if you are staying obd2 motor the crank sensor is down by the crank. and the only thing you would have to do is use a step down harness. you wouldnt need the distributor swap.

the reason obd1 ecu swap... as stated from my boost buddy above is that tuneability is available.

the reason i went obd1 motor..... the block has a closed deck design... will not warp under high temps. obd2 motor has big water jackets and slimmer cylinder lines that could get warped from a highly boosted motor. hope this clears something up. lol

Re: OBDI Swap

despite the fact that you skipped a few words, it made sense.
