Yes, I talked to a couple tuning/mod shops actually. But the difference is that ALL of their customers that did a swap did it in an OLD vehicle that doesn't have the requirements applicable. None had done it in a '96+ vehicle where the rules are completely different.

I had thought about trying to fit the donor equipment to the VX as you said.
This might work. But, I don't have the knowledge required to do this.

Now, if you want to take point, PLEASE DO
I would love to start this project up again, but this time with an LS1/2/4!
(BTW... I too looked into the LS4. VERY interesting option.)
