Alright, I'm gonna step in here and say a few things:
First, welcome. You chose a great car to pick up (or daddy bought for ya). Being 18 and driving a car like this is a great privelige. Not many can do that.
Reading your posts I'm gonna guess that you're a trust fund baby and going to Kettering on your parents dime. Good for you. Don't flunk out.
Now, let's get to the car. The MS3 is a great car, right out of the box. That's why it continues to win comparo tests and shootouts against other cars available in its segment. To call it a piece of s*** right out of the box is sheer ignorance. Sure, to someone, every car is a piece of s***. It's no Lambo, and even then, they have their limits of engineering.
Next, let's address your absolutely ridiculous claim that you'll be smoking Z06's. Someone should slap you right now. Comparing a 263hp, 3300 lb FWD car to a 505hp, 3200 lb RWD car is audacious. No matter what you do, you won't be beating a ZO6, short of installing the AWD drivetrain from a MS6 and stripping the car down, finding a standalone ECU and tuning the biggest turbo imaginable, pushing 30 psi+ on a built motor. Hate to say it, but it won't happen.
Also, you've got all these 'shops' lined up to do your work. Awesome. Let's get some names, websites, etc. and see what they've got. Living in MI, I know a lot about what's going on in the Mazda scene, and I'm anxious to hear where you're getting your work done. All these 'parts' you've got, we've yet to see a pic of anything. No brands, just part names. It sounds like you went on a website, wrote every mod down, and put them in your first post. Nice work.
College is paid for. Congrats. Hate to say it, but noone on this forum (or anywhere for that matter) gives a flying ****. I suggest if you plan on sticking around this forum that you wise up. 18 and stupid is no way to go through life.
