No bolt on, on the market right now, is going to give you 40hp. You might get close to 20 hp with an intake, headers, exhaust combo, but no one makes headers for the altima coupe yet. I couldn't imagine it being much different than the other FWD VQ35DE platforms, even still, they don't exist yet. Really, the only other option would be to go forced induction. A low boost, 5 psi system would give you around 60 hp, which wouldn't be much more that the target you are shooting for. Good luck.
