Hi guys I hopped on over from LS1LT1 pretty much just to ask this question.

I have a 96 OBDII LT1 Z-28 with T-56. Have lots of mods to buying a LS car is out the question, I refuse to start all over. I live in El Paso, TX and we have state inspection. I have no EGR, AIR, cats, rear O2's or anything else emission related. I've been passing because I use the Jet DST to tune out all the codes and I'm friends with a guy that does state inspections.

Now, does anyone know if I do a LS swap will I pass? A very helpful guy on LS1LT1 has told me in Georgia they scan the VIN and when they scan your car their computer is looking for a LT computer and LT protocol.

I dont know if they do the same thing in TX, just want to see what you guys think. I can obviously delete the codes and also change the VIN. Any ideas?

They don't scan for any engine in particular. For 96 and newer vehicles they scan using OBD-II protocol to check if the VIN reported by the PCM is the same as the vehicle's. Since your car is already OBD-II you won't have any problem with that. Of course you need to change the VIN to the LS1 PCM.

They also check if all readiness monitors are passed or not (of course you can make all of them pass with tuning).

The problem is with visual inspection, which seems easy to pass for Texas:

Thank you so much. I have searched everywhere for an answer for a week now and nothing. The visual inspection is no problem because a buddy of mine passes me without even looking at it. So all I have to do is change the VIN and delete any emission codes? Sounds great. LS swap it is.

What engine are you planing on going with? LS1 or some other variant?
