Don't buy the Accord. It is a brick and it is an automatic. Integras have much more aftermarket support, are faster, and weigh much less. If you want economy, buy an accord or civic but if you want more of a sports car, buy an integra.
And you have a lot to learn, young grasshopper. A header and CAI cannot be used for a turbo setup, why strip it if you are going to add the extra weight of lambo doors, lambo doors and altezzas and underbody lights and z3 fenders and flip flop trunks are all rice. Do a little research about this before you commit because it sounds like you took a setup right out of the fast and furious.
