I was wondering if anyone could guide me into what parts would be great for putting into my new Mazda6. The more horsepower, the better. I'm just trying to get around 300+ hp right now.

 

you would have to look into forced induction or nitrous...

 

indeed, i know there is a company that is coming out with a turbo system for the 3.0L. I believe it is Wagner Motorsports. I have also heard of a couple of guys who have blown their motors with Nitrous-mainly because the intake manifold doesn't distribute evenly
