I'll throw my 2cents in. I threw the LS2 into my car because I wanted a reliable fast convertible roadster ( I grew up with Triumph's and MG's). Turbo's are nice and all, bit require a bit more maintenance and care (IF you modify them from a stock GXP). I'm sure some will argue that statement, but that's my belief. A stock LS2 or 3 will be very reliable and require minimal maintenance. Since putting mine in, I have not had to touch it once other than oil changes.
The main limiting factor with our cars is how much rubber can be put on the ground to to transfer the extra HP. My LS2 is bone stock and dyno'd at approx 360 to the rear wheels. With only 360HP, the car can spin the wheels at will in 1-3 and sometimes in 4th if I really hammer it. I'm sure there are a bunch of turbo cars in the same boat. If someone truly want to do a high HP Sol or Sky, whether a V8 or Turbo, you need to put more rubber down. In order to do so, you need a wide body (If you don't want the wheels to stick out of the rear fender wells). I have 10's on mine and they are as wide as you can go and be flush with the fender (PAW sells the CCW wheels in 10'5's but they stick out of the fenders). The frame of the car limits the rear wheel width on the back. Look at the Corvette and see how much rubber they have in contact with the road. The std version has 245's ft and 285's rear, Gran Sport has 275's ft and 325's rear, and the Z06 is the same as the gran sport. To put the power down, we need more rubber on the ground.
Bottom line, I built my car because I wanted too. I could have gone out and bought a Vette, built another turbo motor etc etc etc. Does my car handle good? Yes it does. Dr Dave gave it his seal of approval, so I'm happy with the handling. If my car handled so bad, I'm sure he would have said something so we could improve it. Norms Sky always harps about the extra weight. You'll never notice it on the street, or in the mountains etc. If you were a professional driver on a professional race track you might notice it, but my car will never see the track. I proved myself years ago with my racing skills, I'm all done with that now, so it's time to just have fun with what I want to drive.
Build the car YOU want, don't build what THEY want.
