I just bought a 99 motor, 6-spd tranny, with a FM voodooII turbo
I already have a 99 10thAE with 147,XXX miles and the lady that I bought the car from blew the 6-speed tranny and replaced it with a 5-speed(retard, I know). But w/e I got a good deal on the car. So a came across about a month ago now a guy on craigslist in my area that trashed the back end of his 10 AE miata. His car had only 67,XXX miles on it and a 6-speed. Here is where it even gets better. He had just 2 months (about 1,200 miles) before the crash put a flyin' miata voodoo II turbo kit and a ACT clutch. So I made a deal with the guy and pulled the whole motor(alt, ac, pwr steering, ect still on it), 6-speed tranny, and the whole turbo system. I got a great deal on all of it(I will not say the price cause you guys will hate me). So this is the question I have now is what else do you guys think I need or should get before I drop this into my car? What gauges should I get?

Better control over...well...everything...more power, better economy, safer, really no drawbacks other than a little time and a little money...

It's all good, you'll be ok as long as you at least make it look like you're making an honest attempt to find your own answers before asking us to hand them to you.

keep in mind that you are pretty much limited to 7-8psi TOPS with voodoo box. also, what do you have for timing control as of now? if you have nada, then you need megasquirt.

3 problems with the Voodoo.
1st, it only does fuel. You need the FM timing wheel and are stuck using it to retard base timing.
2nd, you have to splice into your factory ECU wiring harness.
3rd, most people say (and I've seen this firsthand) that you need to max out the adjustment pots on the device just to run the advertised boost. There is no room growth and if anything funky happens (boost spike), you lose your motor.
Very simply, the stock ECU is designed for a motor of specific size, specific airflow, and a specific sized fuel system. If you double the amount of air into the engine, then you must also roughly double the fuel. There are several ways to do it.
Bandaids use several methods, including slightly larger injectors, higher-pressure fuel pump, AFPR, 02clamp... all designed to get more fuel into the engine at the right time while still being at the mercy of the stock injector pulse length. The fuel injectors will only stay open so long... to get more fuel, use bigger injectors and more pressure. You can only go so big with the injectors however because there's no way to reduce the injector pulse length... and at idle, larger injectors will allow too much fuel for the engine to idle correctly.
An aftermarket piggy/standalone that can control the injector pulse-length will allow you to run pretty much any size injector and still retain the stock fuel pump.
Controlling timing is another ball of wax and standalones are much better at timing control than piggybacks... although there are several popular choices for Miatas that do a damn good job.
I HIGHLY recommend selling the Voodoo box in the m.net classifieds and contacting BEGi about the imminent release of the Zoom3... the only budget piggyback that is PnP and will do fuel/timing. Your setup will be very similar to Steph's and I believe she's making 220whp on the stock injectors. It's been speculated that there's room for a little more power by using some slightly larger Toyota 305's or 330's... but that's still unproven (although highly likely).
