Which turbo would best work for what I want to gain?
I recently acquired a 1999 10AE Miata with a built engine that is already tuned. It already has upgraded injectors, a Microtech LT-10s EMS, FM exhaust manifold/downpipe/full exhaust, and a crappy T25/T28 chinacharger that was rebuilt when the engine was built up.
I am looking to replace the current crappy Chinacharger with a better turbo that can help me better match what I want.
My goal is 280whp, and would like the turbo to spool up as early as possible.
For the most part, I am currently torn between the GT2860R, GT2860RS with the .64 A/R housing, and the GT2860RS with the .86 A/R housing.
Which of these would best suit my goals?

Only reason I didn't list the 2560 is I understand that 280whp is at the very edge of what it is capable of.
If I could reasonably get 280whp out of it, I obviously wouldn't object to it either.
Better stated, I guess would be a range... I want to have between 270whp and 295whp, which I am guessing (from what I have read/looked at) would take somewhere around 14-18psi which would be better suited to one of the GT28's...

Won't a 2560 be closed to maxed out at 280 wheel? I know Paul made 300 with one, but thats really not that common.
*edit; OP beat me to it
If you might want more later why not go with a 2871 then? Easily capable of 280 and even 350 without sacrificing much lowend, if any.

Less than 700 bucks and will get you to 280whp easy *With the proper supporting accessories*
Spool characteristics can be found all over this forum. It is a VERY popular turbo.

Ah... So the plot thickens... In reading thread after thread after thread...
I came across the BW EFR turbos... Any thoughts towards going with the BW EFR 6255 or 6258?
I think that either would meet both of my goals...

Damn.
Really kinda seeming like the whp I want is in a limbo area, at the top edge of a 2560, and at the bottom edge of the GT2871R, GT30R's and the 6258... And it seems not many around here like the 2860RS... It will be a couple weeks-couple months before I can get it anyhow, waiting on my tax refund.
Well, Nagase, seeing that you are in Phoenix, any chance you might know of any good tuners down Tucson way, or any tuners at all that are good with a Microtech LT-10s? I've got nothing down here in Sierra Vista.
