Well, for starters, I don't think I've said hi yet buddy; G'day! If you PM me your postal address, I'll send out that sticker :D
Anyways, theres a shitload of stuff you can do to your rolla mate. The first thing I'd be doing is installing some stiffer, lower springs, and perhaps a strut brace to make the thing handle a lil better.
I'm guessing she's not an auto, ay? If shes a manual and you want the car to take off a bit better, try upgrading to a higher ratio diff. Want looks? 16" rims are f@$king huge on a early rolla! Or how about tinting the windows; any car looks better rollin with dark tint.
Droppin in a 5k is a straightforward drop in (thats what I've heard anyway) and supercharging a K motor is always a great idea!
Theres so much to do to the early rollas, where can you start really. Just do what ever you want to do!
By the way, have you got any part cars? Would be interested buddy.
Cheers,
Dan.
