Just got a Z and need to know the first mods to do
 

I've been meaning to post this question sooner but I've been having too much fun driving around. I just want to start off with some mods that will keep my car running good. Maybe things to keep her running cool. Like better intercoolers, oil cooler, better radiater and hoses, downpipes. And some basic stuff like air intake and exaust. Just need to know what stuff I should get first where to order it and things like that. Also when I first drove it home I wasn't good at driving stick and my oil pressure was still in the safe zone but high in the safe zone. So when I got it home she started leaking a little bit of oil. So I took it to a shop the other day and the guy showed me under the car and said the rubber hoses that run from the oil pan expanded a little bit from the place they connect to. He said its a nothing thing and those hoses have to be changed cause they get old and expand from the heat. Now that I drive it good it hasn't leaked since the first two days I got it home. I drove it home from maryland and I live in New york. Is that normal has it happened to anyone. Thanks in advance for the help.I LOVE THIS CAR
