When do projects ever make financial sense? Never!
A friend of mine runs a 2.0 Zetec on Gixxer 1000 bodies, RR'd at 160 odd, but he's running AVO coilovers, polybushed all round, 6 point cage, Mondeo brakes and slicks for Time Trials in our local motor club. He keeps up with Westfields around the twisties!
