ummmmmm in all honesty, does it really matter?
Although I agree, it *does* look like an EF... body mouldings, bumpers, hubcaps and tail lights can all be changed between the 2. I could make my ZC look like a ZD by swapping front grilles and slightly different chrome moulds down the sides/boot too..... but it's still a ZC. The point I'm making is MEH - get back on topic. hahaha.
What do you want from your car anyway mate? First of all, you have to work that out. Do you want a cruiser? A drag-strip destroyer? Something for circuit-work? A drift-pig? A rolling stereo? Or a general all-rounder that's O.K. at everything?
There are so many options, and everyone wants something different and has their own ideas on how to go about it. Either way, the suspension and driveline will be costing you big $$ if you want to do it right... so have a think about what it is you want to achieve, then post it up in here and let us know and I have no doubt that you'll get people's opinions whether you like them or not. Oh don't forget to use your search button up the top if you're looking for "extractors" or whatever as well. Chances are that 100 newbies have come along before and asked all the same questions hahaha

Happy modding
