7mge / 7mgte parts?

[NoMechanic]

Hello everyone!
Hey it's been a couple few years since my last supra. I just picked up an 87 NA, pretty straight body. Just finished peeling off an awful tint job. Starting wondering - What parts from the 7mge and gte are swap able? Are all the cam gears and shafts the same? Are the cranks the same and only have cupped pistons to lower compression on the turbo? Or are the parts so different they can't be used? I haven't tracked down tracked down any performance parts for the NA, everything listed is for the turbo.

Long story short - I want to look at doing some work here and there with the car until after my inventory at work and have a few extra bucks to do the turbo swap (and have done more home work on it). What web sites can be trusted to buy parts from, the suprastore kind of looked questionable to me.

Thanks in advance!
