Its not about "boost", its about how much power the engine can handle.. Since you are 19, take it easy, and just trying for a kit first, before you do all the "internal work". try out about 280-320whp and go from there. If this is your first turbo build, you want to step up slowly and surely. A precision turbo, is just one company based upon a garret cartridge. Garrett and Borg-Warner are 2 of the better companies around.
BUT, before you get all this STUFF that you think is going to make you fast, make sure that you can STOP, and that the drivetrain can handle it. Correct clutch, brakes, and the right management are going to be just as important if not more than simply a turbo kit.
Look, get a budget in mind (remember to overestimate for some of the little things), and make sure you ask yourself the right questions. Not all Kits or even custom setups allow for everything, unless you're willing to ask yourself the right questions, (do you want to keep A/C, Power Steering?).
Don't over involve yourself with all these super expensive Ramhorn manifolds, and 3" intercooler piping, when its not at all necessary for a startup kit. Most of the mass-customized kits (Spoolin Performance, Inline Pro, SLS, etc) are much better than even the Greddy kit (though I love the Greddy Kit, as a starter, it can just be a bit limiting because of the management used and some of the hardware.) and cost the same. You don't need a Full race kit to go over 400whp when you want to upgrade. That's the beauty of turbocharging.
Make sure that you look at the ease / complication of the installation. Ifor yourself, or your installer). 4 bolt exhaust housings and flanges are much easier to integrate than the 5 bolt Ford Style equivalent. My recommendation would be to seriously consider the Spoolin Performance kit.
http://www.spoolinperformance.com and look at the quick 4AC manifold, and piece together everything you need, including BOVs, wastegates, intercoolers, piping, injectors, etc. And the beauty of it, IT ALL FITS NO ISSUES. You can even interchange other parts later on down the line.
Look at the management that is available in your area to tune. Emanage Ultimate, AEM F/IC (check out the comparison on Honda-Tech). Hondata is a great option (look to the S300). Only because of the Crome-days are over. no more damned rats nests of cables and chipped ECUs because you want to be cheap. the better the management and tune, the happier you are.. Some of us, including myself, have been doing this since '94.. trust me, it can be simple, but you must do your homework..
Let me know of questions.. good luck with whatever you decide.
