Neck snap, you mean like from a standing start?
If so, you're just not going to get that without AWD.
Well, unless you have an asston of power and slicks on the rear. Five or six hundred should do.
I say go drive it again. Take a 3.8 out so you can see what it'd feel like once you've modded a 2.0 (if that's the route you want to go).
