Sold off my '99 so here I am with all the turbo goodies:
It was in the car a bit over a year. Not modded at all. I'll also send you my tunerstudio registration. $620 shipped (Sold)
Begi intake manifold setup ( Mazda Miata Intake Manifold 1999-2005
Includes ford 4.6 throttle body (65mm), tps, shortened throttle cable, bracket to remote mount the stock iac (its realllly basic but it gets the job done). TB was drilled/tapped for a pre-TB wastegate line. All you need is a tps pigtail, and ideally some forced induction.
A couple Bosch EV14 injector sets
One set is 850cc, direct fit for a miata. Used them about a month - I was a little overzealous and got these when I still had an MS1. Figured out I was better off with a more reasonable sized injector. $100 shipped (Sold)
Second set is 550cc. Need adapters for the harness (included) and spacers on the fuel rail (not included). These were on the car ~2.5 years. $80 shipped (Sold)
Also, I'm located in northwest CT if there's any local interest in anything.
