Thanks for the comments , the engine is the very same as the radical sr8 apart from the fact this engine has been taken out to 2.8 and a little gas flowing has taken place but utilizing the standard Suzuki valve sizes and stroke from the original. Hopefully achieving 450 bhp and 270 lb ft and revving to 10500 rpm and will hopefully end up with a car weighing nearer to 700kg than 750 kg.
