I am new to this site guys. I am planning on running a 5.3 in a g body regal with n20. I pretty much have the motor and everything with it. It came out of a 2000-02 suburban. I hear some intake swaps and things of that nature are common. This car doesnt have to be an all out screamer just a nice cruiser that can carry the mail. What are some cheaper mods i can do to this motor to accomodate the nitrous? Which nitrous kit is the best for ls motor? How much would be safe running on a stock block? Any help would be appreciated. Thanks a lot.
