i have a 3.5 litre motor from a saturn vue, aka (honda) i want to put it in a datsun z car. was wondering if there is someone out there that can retune the ecu?

for example, take out some of the info that it wants, like traction control, it shuts the car down at 2,000 rpm, security, the second oxygen sensors,

didn't want to really buy another standalone

also, was wondering if there is a flywheel/clutch that will bolt to this motor.
