It's a bit late but I wanted to chime in, bige touched on some good points. Engine upgrades are seldom just the engine which is why I like the moderately modded A series as it leaves room for the other stuff. A full race A14 is around 170HP, so a street engine would likely be around the 100-120HP depending on the tune. Add a 5 speed, LSD diff, brake upgrade, sway bars etc would make for a fun all arounder.

I'm still working on my A-series with E-series head hybrid engine which in the tune I'm looking at will be 150HP (a full race A/Es series dynoed at 186 HP) this could be a bit of fun for a street car but probably not cost effective.
