Hi guys, Newbie here who is not at all technical so be gentle with me I have arrived via a long line of Elises in various states of tune and 255bhp s/c Exige. I have just bought a 2005 1.6 K series Roadsport and am looking to upgrade to Supersport engine spec What is the difference between the two specs and what do I need to go to around 150 bhp? (MEMS, cams, verniers?) Is this the best (most efficient) way to upgrade or should I look at emerald, cams and porting? No doubt I'm not the first to ask this Many thanks for your assistance and patience Nick, in deepest Cornwall
