2.0L 16V c/w throttle bodies and nice set of cams! and if the mood takes you progressive N2O injection just in case you need some extra bhp!!
like i said pick a power you want and go for the engine that is close to that as standard if you want 200+ then 16v are a waste of time, i know RobTs makes more but spending the same money on a 20vt would probably bag you 400bhp
Good luck with the set up. Mid 150-ish hp is around the max and still keep some sort of drivability. It would be good to see the FULL power curve you get from Stealth (or one you have now) and also power at the wheels, the peak number is'nt THE most important thing (though it can give a good overall guide) but the power/torque spread. Also, ask the supplier of yr head/cam what the cam is as you need to know so that the rolling road people have a guide as to how it needs to be set up ! (you can get away without knowing but they SHOULD tell you what they have sold you, unless theres something to hide !).
