new to toyota and have a few questions about my mk3

[Krem]

I am a newbie here, so someone please correct me if I'm incorrect... would rather be educated than oblivious...

I didn't see a cold air intake mentioned here... maybe that's something that already comes installed on a turbo? But even still, there's better ones out there than the stock sleeve.. and if you don't have one yet, I'd imagine that'd probably be your next biggest bang for your buck before going to high priced items...
