2004 mazda mazdaspeed miata mx5 for sale 11
Fast Facts:

  • The first and only factory boosted Miata. The Mazdaspeed is an LS trim Miata featuring a 6spd and an IHI ball bearing turbocharger (factory-developed and installed) producing 8.5 lbs of boost. The compression ratio was only reduced to 9.5:1 (vs 10:1) and the variable valve timing system was removed. Redline was only reduced to 6500 RPM (vs 7000 in base N/A form). Also came equipped with a Denso air-to-air intercooler
  • Mazda modified the 6spd transmission by shot-peen hardening the gears and changing the 4th gear ratio to 1.258. Other factory mods include heavy duty 25mm driveshafts, heavy duty clutch, performance tuned exhaust, and a Bosch torque sensing limited slip diff w/ 4.10 final drive ratio. The steering rack stroke was also shortened from 60.5mm to 53.2mm
  • The suspension sits 7mm lower and features stiffer springs (215# front, 158# rear), bigger anti-roll bars (23mm up front, 14mm in rear), and Mazdaspeed tuned Bilstein shocks. The 17″ Racing Hart aluminum wheels are 2 lbs lighter than the N/A Miata’s 16″ wheels, and they’re wrapped in wider 205mm tires. The result was a Miata that could pull over 0.98 g in the corners
  • The factory installed turbo system includes details such as induction resonators to reduce unwanted noise. Car and Driver stated “The turbo itself is virtually transparent — you can’t even hear it with the top up —and it suffers so little lag that the car mostly feels naturally aspirated.”

Key Model Year Changes:

  • The Mazdaspeed Miata was only produced in 2004 and 2005. There were no notable differences between the two
  • Velocity Red Mica and Titanium Gray Metallic were the only paint colors available in 2004. Lava Orange Mica and Black Mica paint became available in 2005
  • Only 1,428 Mazdaspeed Miatas were produced in 2005, due to a fire at the assembly plant cutting production short. In comparison, 4,000 MSM’s were produced in 2004

Seller Notes:

  • Garage kept CA MX-5
  • Adult owned and well cared for
  • Tastefully mods: Flying Miata Exhaust, AEM Intake, Turbo Boost Gauge, OEM cruise control and final drive ratio adjusted so that freeway RPM’s lower for cruising
