The only bad thing about these cars is that everything is double the price, but then double that because its a twin cam. At least withmy car I have had to replace thing after thing with it, its never ending, but i love it to pieces!!
It's awesome in and out!!
Take out your catalytic converter. I got almost 20 horsepower from doing that (I have a plain jane Z). I can now get third gear scratch, instead of just second gear.
