Show original supplier description
The GForce GF-K20Z33-S adapter kit enables the installation of a robust 2003-2006 Nissan 350Z (Z33) 6-speed manual transmission onto Honda K20 and K24 engines, commonly found in Honda vehicles from 2001-2016. This kit is engineered to leverage the strength and smooth shifting capabilities of the CD009 transmission, making it suitable for various vehicle builds, including those aiming for rear-wheel-drive conversions. The kit is constructed with durable materials, featuring a custom steel flywheel and a 3/8" thick steel adapter plate finished in black powder coat. It also includes a custom pilot bushing and all necessary mounting hardware. For a successful installation, the kit is designed to work with the K-series starter and requires the use of a 350z pressure plate/clutch and throw-out bearing. Compatibility is confirmed for Honda K20 and K24 engines and Nissan 350Z (Z33) manual transmissions produced between 2003 and 2006. To ensure a streamlined installation process, G Force recommends using specific hardware, some of which is sold separately. These include the GF-Z32PPB-KIT for pressure plate bolts and the GF-LSZ32-D for dowel pins. Additionally, K-Series flywheel bolts should be reused or purchased new. Proper torque specifications must be followed, applying Honda torque specs for K-Series crank and block fasteners and Nissan specs for pressure plate components.
