309hp? geez nice work lets see that would be 230kw.. nice one... and as i remember factory was 96 Kw for the SP20/SR2 versions... thats a sure fire rex beater at least! they'd never see it coming...
seriously next time i do go up to QLD i want to see this beast, especially with the turb!!! don't you have real pain in the ass compliance stuff to get around?
if your serious about those times using the same chassis, why don't you go for rotary... i know it is a s*** load of work, but it would definently be worth it, and you could fit in with no wukking furries (except for some fun mods like making a tunnel for the gear box, and diff.. make it worth while and make it RWD, but i'm sure it would be the first 323 with RWD!!!)
oh well happy tuning
