Hey all, I've got a project 2004 Nissan Sentra SE-R that I'm sticking a 3.5L V6 from a 2003 Altima in. I'm not the first to do this by a long shot, but I'm making mounts of my own design on my car. Luckily the transmission mount is the same, the most complicated one is the engine mount on the passenger side. I've got it mostly mocked up, but I'm not sure what's the best way to figure out how to center and level the engine in the engine bay.
I've basically made a 4" spacer to move the factory altima mount upwards, and cut down the Sentra mount to build a flat platform. The transmission mount on the drivers frame rail is my fixed reference point, I've just got to figure out how high to space the passenger side of the drivetrain and where to position in between the firewall and rad cradle.
Overall view:
My mount:
One guy used polyurethane mount inserts that replace the factory rubber on the transmission mount which basically eliminated all give in the mount and theoretically aligned the powertrain perfectly to give equal axle angles....I guess I could pull the upper intake manifold off and use a bubble level to get the powertrain level in the engine bay, assuming I could get the car level first....
Anyone have an easier way, or other suggestions as to how to get everything square? How much does it REALLY matter?
