im 100% sure
1: i bout the car with two engines Lt1 installed LT5 extra
2: i checked VIN and its zr1 matching numbers with the engine i have
3 the previous owner changed the engine in 2001 because of wiring problems with lt5
4: my car is one of only two zr1 in my country, that's why he did the swap cuz no parts available
Well then you should shoot him, because its going to cost you a bucketload of money and a lot of headaches to redo it.
It will be more complex than just a rewiring. I hope he kept some kind of record of everything he did so you have a guide.
Going by the pics, sell all of it and buy a good sound running one
Know its tough as youre overseas but you are still money ahead by starting over. Zs are cheap right now. Clean 40-50k mi cars for teens all day long
Its all the little stuff youll need, the time and headahce sorting it out ugh. Up to you...
Going by the pics, I'd say enjoy your ZR-1 with its LT1 engine! Do whatever you want with all those extra parts. Probably not worth much in your country, wherever that is!

It's unfortunate that they swapped out the LT5 for an LT1, but the LT1 is no slouch. I seem to recall a 1990 ZR1 was around 4.6 to 4.9 0-60MPH, the LT1 is probably close to those times, so other then getting the car back to what she should be stock wise, performance wise I don't think you'll see much.
In my years on the forum I don't think I've ever see someone swap out a LT5 for a LT1 so this is a first, but if you really wanted to get the LT5 back in, since it was originally a LT5 to begin with I'd think it'd be a bit easier then going from the LT5 to LT1. And to change it because of wiring problems has got to be the strangest reason I've ever heard!
End of the day you're gonna be on your own and I highly recommend grabbing some 1990 Factory Service Manuals to do the work.
That poor car looks like it's had an extremely rough life
I wish you the best of luck in whatever you do with it but being that you are in a different country, have a car that is pretty rare to begin with, and have pieces of what once was a hell of an engine with no way to check it, you are in for a huge challenge!
Check out the ZR-1 section on here, lots of VERY smart people willing to lend a hand wherever possible!
Can you take some pics of the rear of the car (the bumper, tail lights, etc.)? The 90 ZR1 is a unique Vette in itself cosmetically. Actually I would like to see pics of the whole car (outside).
Looking at pics of a LT5 and ZF manual don't mean you have a ZR1. Even that VIN looks suspect to me.
What country are you in? Looks like you do indeed have a ZR-1
If your going to venture into restoring this as others have stated it will be a BIG project and may will run into lots of $$. You need to get the motor on a stand and see if the hart of the beast is still fixable.
I just looked at the VIN tag again. Something looks tampered with to me, but I am no expert. You should have others take photos to be sure or google some VIN tags. Your's sure looks like chicken scratch to me.
