Product Description

  • This engine to transmission adapter kit allows you to mate a Nissan 300zx (Z32) 5-speed transmission to a Small Block Chevy (SBC) engine.
  • The 300zx Z32 transmission offers immense strength and smooth shifting.
  • Adapter kit fits any 1955-1985 Gen 1 Small Block Chevy engine that is internally balanced.
  • The kit includes a custom steel flywheel, 3/8" steel powder coated adapter plate, pilot bushing adapter, and hardware.
  • The flywheel can be used with only 1990-1996 naturally aspirated 300zx transmission with either the naturally aspirated or Twin Turbo (TT) pressure plate/clutch setup . The flywheel has provisions for both.
  • It uses a stock 300zx pilot bushing with a machined steel adapter (both included)
  • The kit also uses the 300zx starter mounted to the side of the transmission.
  • This kit will not work with a Twin Turbo Z32 transmission. The TT transmission has a slightly larger bellhousing, which moves the starter out and further away from the flywheel ring gear. Therefore, the TT the starter will not engage this flywheel.
  • The GF-SBCZ32-S uses a 300zx pressure plate/clutch and throw-out bearing. Either the naturally aspirated or twin-turbo pressure plate/clutch disc can be used.
