The last fuel rail you'll ever need to buy!

  • currently in production, so no pics available yet
  • ETA is 7/7/08
  • high-output Miata engines need greater fuel flow than available from the stock single-feed rail

  • to keep price down, we let you supply your own fittings and plumbing (or MiataRoadster can source you any fittings and hoses that you need, ask us for quote)
  • 3/8" NPT female threads on each end provide a larger internal bore than any Miata fuel rail previously available
  • will have a threaded bung with a separate threaded flange (both a flange and a hex plug included) for mounting a stock on-rail fuel pressure regulator or remote FPR
  • for optimum performance, you'll want to get the revolutionary diaphragm-less Synapse Engineering Synchronic SC-004 remotely mounted adjustable fuel pressure regulator (available soon through MiataRoadster)
  • CNC machined from billet 6061 aluminum
  • anodized black with engraved M-Tuned logo
  • limited introductory price is only $99 + $10 shipping to addresses in the USA

GATES RACING BELTS
Fits NA and NB (and other BP/B6 apps)

OEM-quality fit with three times the strength.

  1. Precision belt profile
    Belts are precision ground, not cut, so they fit the pulley with absolute perfection.
  2. Durable heat-resistant overcord
    The heat-resistant blue polyester fabric cover is reinforced with a patented EPDM compound.
  3. Super-strong tensile cord
    High-modulus, low-stretch polyester means Herculean strength for high load-carrying capability.
  4. Heat-beating undercord
    Aramid reinforcement in a patented EPDM compound for three times the heat resistance and durability of standard belts.
  5. Specially engineered adhesion layer
    Patented EPDM compound gives Gates Racing belts extended service life.

GATES RACING RADIATOR HOSE KIT

Replace those OEM rubber hoses with EPDM!

  • HOT TIP: we recommend NA6/NA8 1990-1997 Miatas switch to a NB8 2-hose kit to reduce the number of clamps, joints, and potential failure points (the NB lower hose goes directly from bottom of radiator to water pump inlet, so simply remove the metal pipe section that's bolted to driver's side fender)
  • Gates hoses are made of an EPDM compound that they claim is 10-15 times more resistant to water permeation than silicone
  • see Gates site for details
  • only available in blue NB 2-hose kit
$65 shipped in USA
NA6/NA8 (1990-1997)
