wheres the Mods for an '85

[clark-85supra]

Hello all, just bought my '85 supra, it has a 136k miles on it, runs great. just have some modding questions, and whatever else comes to mind.
First, i thought mkii's had an emblem on the inside on the dash, are all of them mkII's ?
Second, what are some good mods that i can do for the car, headers, intakes, etc...? Im not really to savvy on what stuff is good, though I know not a whole is still available, less Ive been lookin in the wrong place.
I must that Im really impressed by the stock capabilites of my supra, and that I6 sounds mean. I just want to be able to do a lil more, I know the
most common answer is probly to change the engine, but im not quite ready for that yet, are the newer motors inline's as well?
Thanks for your time.
also this is my first forum topic entry ever, hopefully I didnt mess it up. :P
