Hey! Welcome to the forum.
I dont mean to bash, but the automatic transmission will be your weakest link.
Bolt on parts (intake, exhaust) wont do too much in the way of performance on a naturally aspirated car, but will make it sound better. Plus, the trans makes it impossible to get any good power, especially low in the RPM band, no matter what bolt-ons you have.
I say save up all the money you would have put towards bolt-ons, and go for a turbo kit. But then, you have to worry about that auto trans again. They arent designed to be abused or handle lots of extra power.
You dont have to listen to me though. It is your car, do whatever you want. That is the beauty of it all.
