The c4b engine are mafless from the factory.
If your in SA, go see Street Tuna (Martin) as he is pretty switched on and has some good numbers on the board.
HSV (except for c4b engines) vehicles have the same engine (until the VZ's) as the standard Holden range, the main differences are exhaust and tune. With the quality of the tuning software (and more so the tuners) autos can be tune to 190-220rwkw depending on mods, and the manuals can be around 210-240rwkw depending on mods.
Recommend mods are intake & exhaust, another good mod is change the diff gears to 3.9's. No extra power but you will find the acceleration a little more zippy. Not sure but you may wish to check if you have the LS1 or LS6 manifold, if the LS1 you may wish to change to the LS6 or a fast version.
Since you already have these you may wish to visit a tuner and seek their advice before you make a decision. Personally I went for the 1&3/4 DF extractors, custom twin 3" exhaust (but 2.5" should be fine), Ballistic racing cats from Sureflow and DUSpeed OTR.
