Craig, Call Tighe cams in Brisbane about the cams & talk to Dean Tighe himself. I can remember talking to Dean at Tamworth a long time ago about exactly this (i've had an sr20de sitting in my shed unused since 1994) & he said they had at least 4 different grinds for both inlet & exhaust. The 1200 coupe that ran in Club Car (before Improved Production) ran Tighe cams for about 260 hp, with not much else done to it. Also the Morriss brothers in Melbourne used to run an sr20de in a 1600 & Phil Morriss set his own cam company up at some time. Or find a HKS dealer & ask if he's got a catalogue of the cams they offer. Theres a guy at Smithfield who i was going to get some cams from,until he proved unreliable in other areas. Hope these give you some ideas about where to go from here.
