Eric, the 2.7 isn't flawed - you can actually build a really nice 2.7 and keep it very reliable - I built mine following the factory specs for the RS engine (200hp) and kept it all under 6k. But for roughly the same money, you can build a really nice alloy cased 3.0+ which will likely produce more power and last longer...

If you keep the car on CIS there are few nicer cam grinds, and combined with a nice free flowing exhaust will probably yield 15-20 more hp. Like I say though, it's just as good lightening the car and the advantage with this route is better handling.
