Doing an auto to manual swap? One of the biggest hurdles is the converting the tunnel over to the OEM manual tunnel. Not anymore… This tunnel cover allows for a clean installation, and will seal your Supra up from outside elements, heat, exhaust gas, etc.
This tunnel conversion cover was created specifically for the MKIV Supra auto to manual conversions to fit the new Magnum-F transmission. It will also fit the SC300 tunnel.
It may fit other transmission swaps as well as the T56, but I can not guarantee fitment. I know the V160 WILL NOT fit due to the shifter mount on the top center.
This cover was designed and fabricated in house as a much easier solution to swapping out the entire manual 6-speed tunnel swap. This can be done with the dash still in the car! This method saves a ton of work over doing the 6-speed tunnel swap, and leaves the car with a clean, airtight tunnel.
The kit includes the fabricated cover, high quality rubber shift boot, chrome securing ring, and template to use when cutting the tunnel.
This is a bolt in kit, no welding is required. It does of course require cutting out the tunnel to properly allow the fitment of the billet shifter handle. Cutting the auto tunnel is required with any manual transmission conversion, as the auto hole sits too far back.
These are currently only available for the MKIV Supra but I am planning on developing these for more chassis going forward.
DOWNLOAD TEMPLATE FOR CUTTING
This template is only for the MKIV Supra auto tunnel (RHD OR LHD) or Lexus SC300. Make sure you when you print to 100% or “actual size” to avoid the printer skewing the template dimensions, then always double check the dimensions with a ruler/tape measure. Notice the TEXT SIDE IS UP when you put the template up in from underneath to draw your outline for cutting. I included some pictures which should be helpful. Notice you have to notch the bracket for the dash as well.
