You will also need a crank pulley (available from a couple of UK sellers) and maybe a decompression plate. This is the kit made by Blown1380 from the UK. I decided to order the full VMAXSCART kit and never installed this one.
Includes manifold, intake tube from supercharger to carb, idler pulley, gaskets, belt, and fitting bolts. Many people have fitted this kit. It is similar to the Jonspeed kit.
