Show original supplier description
The GForce GF-K20Z32-S adapter kit facilitates the mating of a robust Nissan 300zx (Z32) 5-speed transmission to Honda's K20 and K24 engines, commonly found in vehicles from 2001 to 2016. This setup leverages the strength and smooth shifting capabilities of the Z32 transmission for rear-wheel-drive applications. The kit features a custom steel flywheel (26 lbs) designed to work with either naturally aspirated or Twin Turbo (TT) pressure plate/clutch setups from 1990-1996 NA 300zx transmissions. It also includes a 3/8" steel, black powder-coated adapter plate, a custom pilot bushing, a starter hole block-off, and all necessary mounting hardware. The 300zx starter is utilized, mounting to the side of the transmission. It is crucial to note that this kit will not work with a Twin Turbo Z32 transmission due to its slightly larger bellhousing, which repositions the starter away from the flywheel's ring gear, preventing engagement. The GF-K20Z32-S requires a 300zx pressure plate, clutch, and throw-out bearing. While either NA or TT pressure plate/clutch discs can be used, K-Series flywheel bolts must be reused or purchased separately. For installation, the GF-Z32PPB-KIT (pressure plate bolt kit) and GF-LSZ32-D (dowel pin kit) are sold separately.
