Barely used Alta 42/56 Turbo. $1,250 Larger than JCW turbo w/o losing low end. Gains midrange and highend. See below comparison http://blog.perrinperformance.com/al...turbo-upgrade/ There's a Miata sitting in my driveway with a blown motor after hitting Sebring Raceway. Otherwise I'd be using this right now. Located in Sunrise, FL. Can meet in Coral Springs or Weston. Willing to ship.
