Do-It-Yourself (D-I-Y) S13 Chassis Subframe Swap Kit
If you have been researching alternative methods to significantly enhance the handling performance of your 1985-88 Nissan 200SX (S12 Chassis) equipped with independent rear suspension, you will likely learn many enthusiasts have opted to replace the stock S12 rear subframe with one from an S13 or S14 (1989-1998 Nissan 240SX).
Replacing the stock subframe allows you to take advantage of the inherent adjustability available to the S-Chassis multi-link suspension, along with significantly higher pool of aftermarket products and support.
This kit from PastPower Innovations will provide you the fabrication-specific parts you will require in order to cut, weld, and assist with installing your S-Chassis rear subframe. This kit was originally developed by a member at the Z31Performance Forums, and is commonly referred to as the “ShamWow/MikeG Swap Kit”. Other attempts at providing a swap kit have been tried, but do not come with the breadth of parts and proven usage as the original MikeG Kit.
The S-Chassis Subframe Swap Kit from PPI includes:
Two (2) Subframe Mounting Studs
Two (2) Subframe Mounting C-Channels
One (1) Subframe Stud Retention Bar
Two (2) Subframe Bushing Cups
Two (2) Subframe Bushing Relocation Brackets
Four (4) Gusset Plates for Subframe Bushing Relocation
***Please Note – This swap kit was originally developed for the Z31 300ZX and is usable on the S12 due to sharing stock subframe design with the Z31. However, more work will be required to complete the swap for your S12 – please perform due diligence on issues pertaining to modified strut towers and other slight adjustments before purchasing this kit.***
Note – This kit was originally designed for the Z31 300ZX. As such, there are additional modifications to the strut towers that must be made for the S12.
Club-S12 Forums have writeups on using this type kit, but customer is ultimately responsible for the modifications necessary to complete the subframe swap.
Please note that PastPower Innovations is not liable for any damages caused by improper installation of your replacement subframe – we simply provide the components to make the swap easier. The quality and safety of the installation involves many factors, including but not limited to: fabrication and welding skills, proper measurement and alignment of the subframe, condition of subframe and related components, etc.
