alrite .. i really did search and couldnt find what i needed .. or found mixed answers

if i want to do an obd1 conversion in my car i know i would need:
p28
obd2-obd1 conversion harness
(easy enough)

now i heard some people say that new injectors and new plugs for the injectors are needed, but then i saw a thread that used the same injectors, and just took of the blue cap that was on the plug .. something like that

also i've heard people say i need an obd1 alternator, dizzy

so if somone could just list every part that i would need to do this conversion that would be awesome

alrite well i dont want an obd2 engine in an obd1 car, i don't want to know how to wire, and i already went the the FAQ

all i want is a simple list of parts i would need, because some people say you need some parts taht other people say are not necessary

so like i said .. i did search, and i found mixed answers so if somone could just list the parts i need that would be great .. just like i asked in my first post

the only parts you will need are the obd1 ecu and conversion harness. now if your doing this so that you can run crome or uberdata on a boosted car with dsm 450's then you will need to modify the injector plugs a little to get them to work with the injectors but that really has nothign to do with the conversion your asking about. it's very simple and worth the money.

sweet .. i was hoping all i needed was the conversion harness and the ecu .. thats badass

i heard something about getting an obd1 alternator? .. is that bs?

how is it worth the money? what does it really give you other than bypassing some emissions and ridding the knock sensor? To see anything dont you have to tune it? that runs into the $500 range at least. One thing i never saw the light was, what benifit does just converting an OBD2, to obd1. Dont you have to tune it directly afterwards to fit your setup? I mean the OBD1 doesnt learn your fuel maps like OBD2.

So for people just doing the conversion, then thats it, how does this give them any benifit over OBD2?

obd1 and a chipped p28 can be tuned far more than an obd2 .. obd2 can't even be tuned from my understanding ..

for instance, if i turbo my d16, i can not tune my car with my obd2 set up.. tuning is essential .. therefore i will need the obd1 set up to do so

yeah you won't need to change your alternater

the abilitie to be able to run a chipped ecu instead of a AFC or other piggy back tuning method is worth it alone. conversion harness is about $75 and i chip ecu's so that's alot cheaper then whaterever an AFC is going for now a days. obd2 doesn't "learn" your fuel for you, it still reads from the chip. but when you go obd1 you can burn whatever chip youneed for your set-up. and tuning shouldn't run $500, average price for a street tuned car is about $100-150. if your gonna mess with cam gears and timing to squeeze every HP out of it then you might want to get on the dyno for a few pulls which would be more expensive all depending on how much the dyno fees are.

i don't know of anybody that just does the conversion just to be obd1 and not boost or swap in another motor.
