ISR Performance 415 lph E85 Compatible Fuel Pump Kit for Mazda Miata 89-93

The ISR Performance 415 LPH E85-Compatible Fuel Pump for the 1989-1993 Mazda Miata NA is the application-specific variant of our 415 LPH pump line, with an installation kit that matches the NA Miata's factory pump housing. Built for high-hp builds running E85 or gasoline, with composite impellers for ethanol corrosion resistance.

What It Does

Fuel pumps move fuel from the tank to the engine. As power demand goes up, fuel flow demand goes up. and the factory NA Miata pump runs out of capacity well before a built or turbo'd Miata runs out of engine. The 415 LPH flow rate covers most high-hp NA Miata builds on either gasoline or E85. Composite impellers resist the corrosion that kills standard fuel pumps on ethanol. The application-specific install kit means you don't need to source NA Miata-specific fittings or adapters separately.

Fitment

Designed specifically for the 1989-1993 Mazda Miata NA (the early 1.6L NA Miata, before the 1994-1997 1.8L update covered by the IS-CSEXH-NA exhaust). Includes the appropriate NA-specific installation kit.
