1987 Supra son to own

[LevelCarnivore1]

Im about to buy an 87 supra, its a 3.0 L straight 6 cylinder with single turbo, i dont know much at all about them, but lets first start with the motor, seeing as its going to be an autocross car, what performance parts are available? its a little rough, its been sitting for awhile, motor works though. Second, for some reason it has no fuel system, no tank, lines, etc. Whats a good size and style of fuel cell and what all to go along with it (lines, pump, inline filter, etc)? my third concern, is the interior, its ragged, no carpet or headliner or anything, just seats and a dashboard and both are in BAD shape, so since its a racer, or soon to be, i dont want either of those, so what product could i use to coat the entire inside of the body shell with? I have a jeep wrangler that we had rhinolined inside, functions great, i want something like that. Thanks in advance!

(also might be pulling the motor and tranny and body all seperate, sandblasting the frame, etc, undercoating recommendations? and the hood and hinges are badly damaged, is there any carbon hoods with the pin style hold downs? like you see on street car based dragsters?) again, thanks!
