There's no space to fit a proper FMIC, unless you get rid of the AC and relocate oil & PS coolers.
Exhaust manifolds may be able to flow 750chp, but finding proper turbos that will bolt there and flow enough - is a completely different thing. A pair of used TD05s might fit your budget, but you'll spend a lot of time making them fit.

"Various little bits" are the stuff that you don't count, but it quickly adds up. Gaskets, hoses, sensors, hardware, yadda yadda. Depending on how involved your build is going to be, it can vary a lot.
Bottom line of that message was: don't expect to "cheap out". Again, you can cut corners, but don't expect anything close to "LS community" prices with this car.

You didn't find any details, because there aren't many documented "big" builds. Usually the biggest thing people do - MT & hybrids. And that just barely touches 500whp mark. Try searching for "Milka build thread".
Thanks for pointing me to Milka's build. Thats EXACTLY what im looking for.

Not really sure why cheap/low price would automatically mean barely functioning Frankenstein/cutting corners. There are things that can be built/buy cheap(IC/fuel pump/turbo/exhaust/intake/etc) and things you just have to pay for (inj/tune/ECU or flasher/conversion/etc).

Prior to this car, I built a custom turbo set up on a 98 ws6 for less than 2.5k(including turbo and little things). That set up was my DD at 600whp for 2 years(until I sold it because I wanted AWD Turbo V8 to take care of street traction issues ). That car retained AC.
Before that, I built a 530awhp talon,500hp turbo v8 260z, and a few supras. Currently also working on LS swap vega

Not sure if you're aware but there are turbo's on the market now that runs $350 that last 20-30k+ and able to push 600-800whp+. A single $150 pump can flow enough to run 600whp. I was really hoping people have tried these type of build so I wouldn't be wasting time trying to figure out what to mix and match. But I guess I'll take the hit for that. Worse case scenario I spend what you quote which wouldn't be so bad since I purchase the car rather cheap anyways.

Thanks for the heads up
