Turbo Specialties turbo kit information, review, and installation
it actually works quiet nice (grill). no airflow restriction because it has really large openings and very small mesh gauge. if i remove it, it exposes my intercooler to every cop around which is definitely not a good thing. with grill, it actually doesnt look that bad. AND, if i pop my headlights, it looks like my car is smiling 

that's what black spray paint is for....i suggest you log some boosted run with and without and see what the clt looks like.
You're looking at a gt28r or larger turbo. At 14psi, you are moving past this turbo's efficiency range. This past summer I dyno'ed my gt2554r and hit ~210hp at 11psi. I used FM's base Link maps and made minor adjustments. I'm pretty sure I could have it 230hp at 12-13psi if I knew what I was doing. Either way, any miata with 200+ hp is a blast to drive.
i think given a bigger DP you could hit 230-240, without the WI with the WI and some agressive timming i think 250 is acheivable. Given the size of your IC i would start sprating at 8-10 psi what size nozzle do you have?
Race gas or 50/50 water/meth buys you a lot over just boost (and just WI). You could hit 250 with your turbo at about 16 psi as magna said and you'll be able to run a good amount more timing.
