Wait, how may Pro 5.0 guys are using twin setups?? Twin turbos will never outflow a large single turbo.

You're going to go to the junkyard and get a turbo that you have no idea how long the life will be and expect it to be reliable?!

And I'd like to see a 600 HP daily driven car hold up on the stock internals on pump gas.

Anyone can come up with some Track Car that is fast for 9 seconds at a time...but I'm talking for Daily use, in stop and go traffic, and being able to run for extended periods. That car may be good for a little less than 10 seconds, but try to drive it for about 30 min and I bet something will melt.

You have to compare apples to apples. We're talking about options for a street car that has to be reliable, not some track-only car.
