That is fantastic! I have owned many, many, many outrageous cars and out of all of them, my boring Cadillac CTS-V with a messaged LS-6 and Corsa exhaust sounded the best, even better than the 355 I had. There is just something about the sound of an American V8, AND the torrque curve!!!!!!!!!!!!!!

A bigger turbo will make more power. Is that so hard to understand? A big turbo with variable geometry will have linear spoolup. Is that so hard to understand? In theory, it doesn't matter what displacement you have. A smaller turbo engine can always be modified to produce similar results to the larger naturally aspirated displacement engine. From what I gathered, I thought we were comparing small displacement turbo engines to naturally aspirated large displacement engines. Large displacement turbo engines do indeed provide superior performance, however in the real world they suffer from excessive traction problems and massive reliability problems (can you say shattered drivetrain?). In the end, its all about what the target horsepower level you want, and what kind of power/torque curve you want. If your target is 2000 HP, sure then yes I would choose a variable turbine turbo V8. Wait a second, who the hell needs 2000 hp? Maybe an alcohol powered rail car dragster. When your target horsepower level becomes a little more realistic, say around 1000 HP, there becomes less and less need for a large displacement engine to do the job. A large displacement engine should also be avoided for these reasons:
1.) Cost
2.) Complexity
3.) Center of gravity (V8's usually have a much higher center of gravity than inline four cylinders)
For low power (realistic) levels, a small displacement engine can easily be made to to perform well with modern forced induction technology while also keeping the cost, complexity, and center of gravity DOWN. A high tech, lightweight, small displacement engine to me has a distinct advantage on a race track versus their higher displacement V-configuration counter parts. Displacement IS still an advantage (since it will always allow better power curve and a higher theoretical power output), but it definitely does not come without its disadvantages.

Different strokes for different folks.
The LS7 has 385lbs of tourque at 1600 rpms, is there a 2 liter out there that can do that.
(Although I did mention a corvette engine

I almost did this swap on my old BMW M Coupe... then I sold the thing for an Evo.
I like what the guy did here. The Evo isn't a rare collectors item per se... it's a relatively average priced performance vehicle that's usually modified anyway by 95% of it's owners. You don't see guy's griping about suspension swaps do you. "I'm a Bilstein die hard... putting Ohlins on an Evo is blastfemous!" He he.If this guy can mate something like a GMC Typhoon awd tranny to this LS1, this thing will be pretty sweet. It may not be a techno whiz bang like an R34 or Evo X, but it will still rock none the less when it gets completed.

I bet the weight distribution isnt all that bad. The transmission is off the front end now. It might be a V8 but its an alloy block (or could be if push came to shove) with alloy heads. I am thinking overall the front weight could be really close to 4G63'd Evo.

its an aluminum block and it seams lighter than the stock 4g63 because the front coilover is at the lowest and still there is 2" finder gap .

If you can't put an Evo AWD system, just leave it rear wheel drive. I'm pretty sure an AWD system from some truck will cause it to handle worse. With rear wheel drive it's possible that it can handle better than stock with a properly calibrated suspension system.
