The .86 has more power higher up (400whp) and a little more lag (Spools up 400-500rpm later than the .64 trim) Either way you could run a 2871r with lower boost and leave some "room to grow" because speed is addictive haha. Running lower boost will also preserve the turbo. If you want more power, just turn up the boost! But if you wanna save a couple hundred bucks just get an s15 spec r turbo as posted earlier.

2. You'll need at least 550cc injectors. Deatschwerks is the cheapest place to go. If you get the gt2871r get some 740cc injectors (Or at least 650cc injectors) and run them at a lower duty cycle to leave yourself "room to grow," or stick with the 550's if you go with the s15 spec r turbo.

3. A z32 mafs will be necessary for over 240whp and is good up to 500whp. Any more power and you'll need to run a map sensor.

4. Speed costs money. You gotta pay to play. You could get a mail order enthalpy tune for $500 but it won't be spot on (Mail order rom tunes will never be spot on) so you'll need an safc for ~$200 to dial it in and pay another ~$100-$200 for dyno tuning. Total cost will be ~$900.

OR

Get enthalpy (Scott) to real time dyno tune your car (He's in florida so location might be an issue. Also don't know how much he charges) but Scott is a REALLY good tuner,

OR

Get a power fc. It's the least expensive standalone and is tried and true among tuners. In any case, real time professional dyno tuning is key.

5. Sorry, I don't know anyone who runs emanage.

These are just general pointers from personal experience. Good luck and hope this helps!

+1 for the emphasis on a good tune.
