Buying Guide: Key Purchase Considerations

  • Compatibility: Confirm engine model (B16, B18, B20) and whether the bolts fit your block, bracket, and trans mount configurations.
  • Material and Grade: Look for high-tensile steel or 10.9-grade hardware for durability and rust resistance in harsh under-hood environments.
  • Completeness: Decide if you need a full kit (block to gearbox) or focused hardware (valve cover or bell housing) to minimize waste and cost.
  • Corrosion Protection: Rustproof or coated fasteners extend service life in areas with moisture or road salt exposure.
  • Installation Considerations: Ensure the kit includes the necessary washers, nuts, and spacers or verify what else you need for a proper fit.
  • Installation Time: A complete kit generally saves time by reducing the need for sourcing extra bolts separately.
