at 60,000 I can get a car with a brand new power/sport/race oriented 4.0L V8 with a 8400rpm redline and great powerband in a host of configurations manual/smg etc with plenty of space for upgrade-ability....yet at 75,000 I get a Camry motor that needs to be upgraded to feel "right"

It's a good engine regardless of cost and negative stigma associated with it coming out of a Camry.
It makes around 310-320 hp at the crank with all 3 cats, with just minor bolt-ons (my 271 rwhp dyno). With headers and a tune around 340-350 hp (MWR 295 rwhp dyno in their swapped Exige)
It's lame that Toyota and Lotus did not let it breathe, and it's really lame that owners of expensive Evoras have to get a few bolt-ons considering how much they paid. BUT the engine itself is excellent. I know the engine inside and out, it is HUGELY underrated. The engine itself is worthy of being in a $60,000 sports car if it had the "full-package" engineered to go with it.
The 2GRFE actually has the highest valve lift and the biggest valves of any previous Toyota engine (including 3SG, 2JZ and 2ZZ).
2GR-FE/FSE
Intake valve diameter: 38.0 mm
Exhaust valve diameter: 32.0 mm
Intake valve lift: 10.9 mm
Exhaust valve lift: 10.7 mm
Overall intake valve length: 105.85 mm
Overall exhaust valve lenth: 110.4 mm
Valve stem diameter: 5.5 mm
For example the 2ZZ has pretty big valves, but still are smaller than the 2GR valves (2zz Int = 34mm and Exh = 29mm).
Since you brought up the M3 engine (which is awesome, but look here, pretty close and actually smaller than the 2GR valves)
2008 E92 M3 S65 Intake valve:
diameter: 35.7 mm
stem: 4.97 mm
All an Evora needs is a Radium Intake and a Cat back, and it's good to go.
It can also take a beating.... Here's one in a dune buggy that makes 800HP

Not saying that Toyota/Lotus didn't screw up on their applications of the 2GR. Just saying the 2GR is more awesome than people know.
