Well as you can see from my sig I have my heads and intake, getting ready to buy my catted x, and after that, cams. I plan on having modular depot install it all and tune it for me this spring. I'm thinking I'll have close to 270 rwhp with all that and a good tune. Obviously my next mod after that will need to be tires, because mine are horrible. Can my car support that kind of power? I'm mostly worried about the rear end. I've heard that the stock rear end can handle up to about 350 bhp. I plan on probably doing 3.73 gears, because I do most of my commuting on the highway. Should I build up the rear end? If so, can my stock rear end support that added power long enough for me to save up for a built rear end?
