Q: I was wondering if it would be legal to swap my vq35de motor out of my 350z and replace it with a ls5.3 vortec motor

asked by on October 12, 2016

I wanted to pull the stock 350z motor out and put in a 5.3 ls vortec. I was told it needs to pass emission s and inspection and have the computer match the car? Like the chassis Vin in the ecu?

My car has 113000 miles.
My car has a manual transmission.
