This Lotus Exige S packs a punch thanks to a switch in boost from the factory supercharged Toyota 1.8L engine to a now Garrett turbocharger. Weighing under a tonne this Lotus is a cracking street and track car all in one.

Mazda RX3 13B rotary turbo

20B RX-7

Ross' immaculate Mazda RX3 runs into the 9s for the first time. The new car is powered by a Promaz Automotive 13B bridgeport rotary engine and aided by a Garrett turbo and MicroTech EFI. Ross has fitted an Albins gearset to the Mazda RX-7 gearbox. The RX3 was only on low boost this time out so expect the guys to run a lot quicker yet.
