yeah, for that HP level, you'll want to go the MAP/ standalone route...I have no idea which is best, because I have never used any (eventhough I have a power fc for an s14). I have similar goals (horsepower wise), but my main thing is to do it on a stock bottom end (and have it last). I'm shooting for 400rwhp on pumpgas, and 500+ on methanol and pump gas....haven't full decided on the turbo yet, but the precision pt61 looks to be the one, it's a full T4.

I also plan to have my ecu re-tuned to where the airflow values are halved.....so that I can run two z32 mafs, and not have to go standalone.....it'll get me past the 500rwhp barrier. This has already been pioneered by JWT on the 300zxtt...I had that setup (dual pop) on my 300zxtt, and it worked great, I don't see why it won't work on an sr.

I guess you can call my build a high HP budget build. I'm only using what I deem necessary to get to my goals reliably.
*850cc denso injectors
*z32 maf (x2 for later higher hp)
* tuned ecu
*255 walbro fuel pump
*greddy knockoff intake manifold
*SSA top mount T3/T4 manifold and 38mm wastegate
*3" turbo back exhaust
*FMiC
**272/272 Toda cams 10.5mm lift (still on backorder)
*electric radiator fan

everything with an * next to it is on the car now...chances are nothing else (power wise) will go on the car. The only thng I know I will change/add is the turbo, and I will add an alcohol injection kit.

Right now, I have an ssa bottom mount manifold on the car with a pulsar gtir t28 running....it makes 290rwhp and 258rwtq @ 15psi.....this turbo can be pushed to 18psi on 93 octane (I just never bothered to turn it up from where I had it when I ran my stock t25) the stock t25 made 237rwhp and 255rwtq @ 15psi.

The turbo I have right now is a T3/TO4E...57 trim, .50 a/r compressor and .63 a/r, stage III wheel turbine. I'm hoping to make ~350rwhp at the same 15psi with this turbo. I'm supposed to be putting it on this saturday, so I should have dyno numbers within a few weeks....then it's time for the pt61 (or whatever big turbo I finally get).
