What would do you guys suggest to begin with for a 2005 ZX3 SES (D20)?
Seeing as I don't bring in the greatest amounts of $$$ I'm looking to get the most performance/hp for the cheapest money to start off.
Are we talking cold air? or Turbo haha. If you could help me out a bit more I would appreciate it. Still new and don't want to  up my first car. Also it is still under warranty, so if any of this would void warranty let me know.
How about tinted windows? That was my first mod and probably my favorite! Anyways he was talking about a Cold Air Intake from Marcy or Focussport.com...I got mine from FS and it's awesome! That and a custom exhaust system will get the motor flowing freely and you will definitely notice a gain of power. I dunno what a rear engine mount is. somebody else wanna explain that one? Intake is usually the first mod people do.
if you add a CAI, and then the next time it rains really hard you show up at the ford dealer with hydrolock issues, they will probably point to the CAI. that said. if you put a CAI on your car and then a couple of days later your exhaust falls off, i highly doubt they would have any case saying that it was the CAI.
as you can see in my sig, i have the rear engine mount. it made a world of difference in shifting, and some people recommend to get it right alot with the short shifter.
