Ok! So I just got me a Mark 4, 1993 totally standard Supra, Standard wheels, standard exhaust and body kit.
With a very nice rear spoiler, In silver, manual gearbox.
Yes I am looking at bodykits, But what can I do engine wise? Suggestions?

you can go I/H/E , or you can go T/H/E, cause with a turbo you wont need an intake.... but t/h/e will be WAY mor expensive than i/h/e, but you will also have much bigger gains. its all about the money, if yu can afford a turbo, i say go for it. You ca also get lowering springs or a coilover kit (im not sure if they have coilovers for supras but if they do thats cool). There is also window tinting, and tons of other stuff. personally id go for the turbo but you are gonna have to do alot of work on your engine, cause u gonna ned a boost controller, a gauge, maybe reprogram ur ECU, etc... so if i were you i would decide what you wanna do with the car. race? showroom? daily driver? then go through and think of what would benefit you most .
