A couple of big cars caught our attention with a Rallye sporting an R36 lump and J-Tec Automotive's track attack Mk2 440bhp 1.8T packing some crazy motorsport technology. How about rear wheel speed sensors from a Mk3 VR that are linked to the engine ECU to dish out variable boost through the gears to optimise traction? Starting with 8PSI in 1st and spiking at around 25PSI in 3rd and 4th. How mad is that?
