It's the same engine as a normal GTT apart from a genuine Group A carb (150 main, 27mm Venturi, Brass enlarged Aux Venturi and a .9 a/c), Devil strut brace, Devil side exit exhaust, 1bar boost (Actuator set), TDC wire swap (Advances ignition), coolant system modified (HEader tank located in scuttle area), Intercooler has more cowling to direct air through it better.

They used standard 25mm carb's.
