Hi All.
I apologize in advance for:
a) Lack of mechanical knowledge
b) Lack of mechanical terminology
c) Lack of the ability to create a proper disclaimer-apology-list.
I own a skyline which has been off the road for almost 9 months now, at a very reputable shop in Melbourne. It was a NA+T (R34 GT Sedan) that has been decided the best course of action is to put in a GTT Engine.
However, the car is an Automatic. Apparently this causes a massive issue for my mechanic as they seem to be rather stuck with how to proceed. The car is stuck in limp mode, and due to (reasons unknown to me, and them) they are unable to get a reading from the ECU to find out why. (it is a stock ecu)
The only reasoning they can give is maybe the R34 N/A Triptronic has a different computer and setup to a R34 Turbo Triptronic Auto ECU. They are pretty much clutching at straws here when it comes to this, so I appeal to the gods of the internet to provide some insight or a link, or some documentation, or an olf wives' tale even as to the differences between the two gearboxes.
Everything else has been replaced engine wise, so effectively they are trying to get a RB25DET Neo engine working with a R34 N/A Transmission (which has been updated with a MV Auto shift kit, if that helps any). All the wiring and loom has come from the turbo engine. Nothing else from the original N/A Car is connected.
Anyone ever done this? Is it doable? WTF is going on here? Winning answer I will literally pay for a slab of beer to your most convienient location.
