Since the GTR has come out there has been a lot of advancements in aftermarket support. But yes trans fluid is pricey. I paid I think $480 for my dodson trans fluid.

OP- I would not shoot for over 600 awhp on stock rods. But even at around that power that is a mid 10sec 1/4 mile car easily. And it will hold its own on roll racing. You could easily just throw piston and rods in the bottom end and be good for A LOT of power. The next failure point would be the trans, which is big money if you want bug power to hold. My trans costed me $26k. But there are options for around 7k that will hold a good amout of torque. I would just keep it simple. Throw piston and rods in there, do a small SIR turbo upgrade, you could wait on the trans and keep power low or go with Stg2/2.5 trans upgrade from shep or ssp. Simple two walbro 485s pumps, and some injectors (ID1000/2000, SIR injectors, etc), then get it tuned with Cobb. You will be faster then most things on the road with that super simple set up and still be daily friendly.

I have a 2010 GTR, an 03 M3 turbo,and an 03 996 tt all with ProEfi ECM with flex fuel and a great tuner, nuff said. If u ended up buyin a GTR keep it around 650 awhp for longevity and reliability it's more than what u need on the street.

But it sounds like a build from them will be over the budget you wanted to stay with. If you are looking for power you described, just keep it super simple with bolt ons. Just find a good tuner for a custom tune. Tim Bailey might be the closest to you but himself and well as other can go email tuning with you. Which would be just fine at the power level you are trying to achieve. Good luck on the search bud.

Simple bolt on stuff has typically been reliable. Built engines, standalone ECU's, etc., can be quirky and problematic. Not always but often enough. Anyone who says otherwise is kidding themselves.

And Pro Efi (Jason) is releasing there new version very soon. And yes Pro Efi worked really well in the Supra scene with true dummy proof flex fuel set up. There are only a few GTRs that are running flawlessly on Pro Efi.

Syveccs, I am not sure about true flex fuel. I never really cared since it so easy for me to change maps on my Cobb and if I decide to go Syveccs I dont "need" the true flex fuel ability. Its more of all the failsafes and how fast the unit works. And where I get my pump E85, I have ALWAYS get between E83-E85, most of the time its E84-E85. I know because in my Built Stroker Super I have a Ethanol content digital gauge.

Also for the OP. A bolt on GTR running E85 on a good tune will light up a 700whp Vette. :-) The GTR is a over al better car then any other car you have listed. I know from personal driving experience. Not just biased to the GTR. The only other fun car that I would look forward to buying is a 997 GT3RS.
