This is the same way I look at most of the builds me and my husband have done. We do it because we enjoy the work and enjoy driving them afterwards. We do not build them to others taste most of the time, because we have no plan of selling them in the long run of things.
I don't think you'll find too much
argument around here, as that's the reason just about every build on this site is unique.
As I have been doing some looking around, I have found one change I will have to make in the suspension, the GTR uses struts at all 4 corners, I will either have to find a way to build a mounting system for them or change them out for regular coil-overs.
While I've never played with one, everything I've seen says double wishbone at the front and multi-link at the rear.
Typical to production cars it does place the coilovers very much outboard and vertically to maximize inboard space for other components. Due to the driveshaft going 'through' the bottom of the shock, keeping the stock type components will still make it difficult to position them differently even if you can move the engine back from the front differential and shorten the main driveshaft. Either way you'll likely need to significantly change the spring/damping rates, so custom aftermarket coilovers of some sort will probably be required. It also does have the tall front upright design that comes up around the side of the tire. So stylistically it might be a bit tougher to keep more of an open wheel look if that's what you still wanted with this new drivetrain. With the components you have to work with, it would probably be easiest to package if you modified the plan into a full bodied car. Which when you're talking about the extra effort of doing things like rear transaxles for their potential performance advantages on front engine cars, would likely be worth looking at just for the substantial drag reduction that would result from doing so.
