This mounting kit is designed to provide an OE level of fit and finish, providing an easy bolt-in installation of a LS series engine into the S30 chassis.
Please see the product development page for an indepth look at this kit. I have detailed the design and development process starting from engine scanning and ending with fitment in our development 1972 240z with a LS2 and T56 transmission. We have strived to provide the highest quality, highest value kit on the market allowing for a bolt in installation of any LS engine to the S30 chassis; 240, 260, or 280z. This kit was designed in CAD and is constructed from laser cut steel, professional welded in fixtures to ensure accuracy, and then powdercoated a durable 80% gloss black.
Kits are now available for both the 240z and the 260z/280z. 240z and 260/280z transmission tunnels, floor pans, and rails are quite different requiring different transmission crossmember designs. In each case they have been designed to maximize the space available with provisions for dual exhaust. Please see the product development page for more information.
The kit is designed to work with either a C6 LS2 Corvette or F-Body oil Pan. Clearance is provided clearance for long tube headers such as Hawk's Third Gen and CX racing but will not work with shorties. Clearance is also provided for both the stock A/C compressor or a Sanden unit, however a custom bracket to clear the frame rails is not yet completed.
