Swap?
Hi
Well, a mate just did a similar V6 swap (VT to VN)
The main issues were with the management system. You need the computer and harness for the VS engine too. If you want to keep your transmission (auto?) you will need to get the memcal modded to write out the gearbox bits. Also you will need the antitheft lock stuff disabled too otherwise you will need the key, lock and body control module that match the new computer.
A few other things around the engine are different. A/C compressor mount, starter motor mount come to mind....
It is not a job for the fainthearted and you will need money!
Cheers
