my car is a 95 OBD1 LS. I'm gettin a 99 LS swap. My question is can i use the 99 OBD2 motor in my car if i swap the whole fuel rail, injectors and intake manifold from my OBD1 motor. I know i would need to swap the OBD1 dizzy as well.

let me know what i need for the swap to work.

 

engine and computer for starters.

 

Yeah basically just use the newer longblock with all the obd1 stuff (IM, injectors, dizzy, alternator, etc) for the least headaches

 

ok, since i can swap all my OBD1 stuff onto the Newer block, i shouldn't ahve any problems correct?

do i need to swap the obd1 alternator to the new motor as well?

yeah, i'm jsut gona take everything from the injectors back and swap it over.

 

I believe the obd2 alternator is a different plug than obd1, you can use it but you would have to rewire it. If your obd1 alternator is good, use it. Keep the obd2 one around as a spare. Same with the dizzy if your obd2 engine came with one. Hold on to it as a spare since you'd just have to rewire the plug to use it.

But yeah, swap over everything you can to the new longblock and you'll have no issues.

 

ok great, jsut swap injector, IM, and alternator from my OBD1 and i shouldn't have any problems correct?

Dont OBD2 motors have a wire for the crank pulley??

 

you could probably just leave the CKS unplugged (you won't have that plug on your obd1 harness anyway).

 

ok, i'll jsut cover it with electrical tape or something. Thanks for the feedback guys, gona do my swap this weekend. maybe i'll post up some pictures.
