Question type: Car Customization

I have an 07 Pontiac GP/GT, and it's completely
stock. I intend to put a lot of time and hard work
under the hood of this car. Where should we start?

Check out ZZ Performance . They have lots of upgrade packages for your car.

Theres a lot of pro's & con's about bolt-on performance like cold air kits, exhaust systems, & MSD ignitions. But the most bang for your buck is a high perf cam & kit. And buy another cylinder head(s) & have it modified with a port & polish job, & bigger valve springs that come with the cam kit. Then when you're ready, install the modified head(s). Seek out a good cylinder head shop for qualitly & prices. Some people use Dart or Eldelbrick heads, but much more expensive.
