as awesome as that would be (and I would love one) the reality is it will need a skyline gearbox and diffs to be anywhere near reliable and used hard, with that in mind its a lot cheaper and easier to just buy a gtr.

my r33 was only £15500 640 hp and can use it all put it down and nothing has broken yet (touches wood) lol
I would love an escos its just the cost that puts me off if trying to run nig power and make it reliable
