Hey everyone!
This is my first post on this forum, and this place seems perfect for my needs.
I own a 2005 Pontiac Sunfire, and I love it to death. However, I'm feeling the need that most people do at some point, and that is the thirst for more power.
Now I know that a lot of people will say that I shouldn't invest a ton into something like a Sunfire, but the car has a LOT of sentimental value, so this is my car of choice.
From my very scarce car knowledge, I've thrown together a small list of parts that seemed to be suggested for power enhancement.
So my questions would be these, are these actually the ideal parts for price/performance increase, and in what order would you suggest I acquire them? (Everything in the car is stock at the moment.)
My funds are going to pretty much be non-existent until the Summer, and even then I'd doubt I'll make enough funds to get the parts quickly.
I would probably end up having a dealership do the installs, seeing as I don't believe I have the knowledge to do it properly.

Looking forward to any advice you can give!

For the m62 I'd piece together a kit from a cobalt/ion and save yourself at ton of cash. here's pretty much everything you need to know about the m62 and adapting it to a jbody.

For exhaust, I'd just buy your muffler of choice then have a shop fab the rest of your system. If you're supercharging, a new header would also be a good investment. The Pacesetter 4-1 is great for a blower app, and the LSJ version is bolt on for us and offers a bit bigger diameter. I'm running a pacesetter lsj headed into a 2.5" stainless system with a Silverline resonator and Dynamax super turbo muffler.
Any off the shelf intake will need to be modified to fit since the throttle body will be located differently than the stock setup.
