For my Z24 project, swapping a 3500 into it plus upgrading to OBDII, I was told I need a harness off of a 96 Beretta with a 3.1, along with several other engine parts for a 3400.
How similar is a 96-99 Achieva with the 3.1?
I can get a whole car just 2 miles up the road for less that $300 if it has what I need.
Thanks

I have researched about all I can, and from what I can tell a 97 Achieva is almost identical to a 96 Beretta as far as engine, pcm, and harness.
Despite what I was told, I think I will pull the trigger on the car.
Even if it is more work, it will save me over $1k in parts.

why bother with all the effort of OBD2? Lots of 3400 and 3500s are running fine on OBD1. Just swap a few pig tails and its rolling.

I had problems finding an PCM and chip and someone to tune it.
My Z24 did not come with one.
