FP Miata Conversion

• Keep all of your spare parts
• You will be surprised at how stock you can build
  an FP car
• Use the complete stock brake system
• Do Not use aftermarket Brake Rotors Use only
  Mazda rotors
• The only stock electrical I used was the starter
  wire and brake lights!!
• Keep it Simple
• Just because the GCR says you can modify doesnt
  mean you have to
• Find a reputable dependable engine builder
• These engines could be a little sensitive if not
  built exactly right
• Rear Wheel HP
• EP Mid 180s with a 1.8 motor
• FP Mid 140s
• GTL Basically an EP motor with the 24mm SIR
  High 130s

Pros and Cons

Used pro built FP Miatas Mid 20s Cons More expensive than SM Overall Cost of Ownership is considerably higher Cars need more maintenance and upkeep Maybe just a tad more sensitive to component failure from higher corner speeds, vibration, higher RPMs Fiberglass body panels easier to break with contact Motor refresh every 13 15 races weekends (FP) More stress on entire drive train Tires to buy/mount/balance is right at 1000 per set Race Fuel instead of POG New Pro Built FP - 50K
