TLDR
2300-2400 lbs.
155hp 150tq stock
235 hp 238 torque on pump gas
259 hp 291 torque on e85
TurboSource’s Miata now makes 235 rear-wheel horsepower and sends 238 pound-feet of torque to the ground on pump gas with the addition of their in-house designed BorgWarner EFR 6758 Vband IWG turbocharger kit (running at 10 psi in this configuration), along with a three-inch stainless steel catback exhaust of their own design and ECUTEK racerom software tuned by Matt at OrangeVirus Tuning.
Using E85 Flex Fuel and 13 psi of boost, the MX-5’s turbocharged 2.0-liter mill makes over 259 horsepower and 291 pound-feet of torque at the wheels, gains of 115 hp and 9155 lb-ft. You’d better believe that’s a noticeable improvement..
That’s a substantial bump from the stock output of 144 hp and 136 lb-ft on the dyno, and as much as 259 horsepower and 291 pound-feet at the wheels can be had using E85 Flex Fuel and 13 psi of boost. And that’s with the use of the stock drivetrain and fuel system.
