The 20B-REW already comes with a perfectly good fuel injection system and twin turbos. Why would you want to remove all that just to add a pathetic carb and make half the horsepower when an EMS only costs $1,500?

The single piston front brakes are just fine for a street car. I don't think they really make much difference until you put the car on a road race track like Sebring. If your car has trouble stopping ONCE from a 140-150mph drag run, then your brakes need to be fixed, not replaced.

Your car can have the same static weight distribution if you build it correctly. Even if you don't make plans for proper weight distribution, it still won't change significantly. If you think about it, large radiators, electric fans, CAI's, and FMIC's all add weight to the front of the car, but you don't see anybody with these mods complaining about their static weight distribution.

The 20B will worsen the polar moment of inertia some, but I don't think it's a significant amount. The main handling problem in a 20B swap caused by making the front sway bar and/or steering rack clear the oil pan.
