Hey Man
I would start with
Hose Techniques Kit For Toyota Supra 1993-98 Twin Turbo-- Replaces any old tired hoses and makes your engine bay bling
I have a Polished Rad Panel, real bitch to keep a mirror finish(watermarks) I gave up, you would have to clean it everyday, get the APR Carbon fibre radiator cooling plate off Whifbitz; I can show u at the Supra weekend in July
Rad Cap
Rad Pipes, look good and also replaces the old tired ones
Spark Plug cover ( I have carbon one off Whifbitz, excellent quality)
Next you are talking Cam Covers, Throtle Body, Intake
