There's also the "rare" and interesting setups as well, like the short-stroke 2.5, 3.4 etc. Or a 2.7,2.8,3.0 MFI RSR kinda thing.
Or the really really $$$BIG$$$ guys like the 3.8's with custom everything.
Not impossible to spend 30-40K on the powerplant alone if you really try.
Overall I agree that the "sweet spot" for most 914 guys' needs is probably the 2.4-3.0 range.
I do love the zingy small sixes but torque is what gets you away from the red light, or slingshots you off the apex. And you really have to wail and thrash (rev-wise) on most of the 2.0-2.4 motors to stay up in the powerband. Takes a different kind of driving then most of us 'Muricans are used to. For example my daily driver S4 pulls like a freight train from about 1800 rpm's on up, in at least the first 4 gears...try that with a 2.0-2.2S motor. (No don't, it will hate you).
I have no idea what I will eventually do on my sixer but very likely a massaged 3.0...after that bathroom remodel for the wifey is done
