I fully understand what you're talking about. It's really hard to understand until you've built a big turbo car. I know a bit about the loss of fun factor because we recently upgraded my friend's car from an Evo 16g to a 61mm turbo. No real power until 5000 rpm. All the midrange he loved was gone; the turbo was only fun WOT on the interstate. The car's been down a while switching to map-based tuning and turning into a weekend warrior street/strip car so it's fine but it did teach us a lesson about fast vs. fun.
I think my ideal setup would be a 10:1 2.3l with an FP3052 and methanol injection or a dual-fuel setup and a cyclone manifold. 500 whp peak, but awesome power from 3500-7000. I have the cyclone manifold, now I just need the 10:1 2.3l, the FP3052, and the dual-fuel setup with EMS.

(I'm actually going to be running an Evo 16g with cyclone- both of which I was actually able to afford unlike the above).
I think I might buy a 2g one day to build a setup like that with the superior suspension design of the 2g, the better looks, nicer interior, etc.
