What makes the boxer configuration superior in these respects?

Seems to me turbo-charging is just more complex, given the 2 exhaust manifolds as compared to 1 on the inline. Other than that, I don't see any difference.

And I'm too lazy to explain a boxer engine to you!

Daemione, turbocharging a boxer engine is no more complicated than turbocharging a V-configuration engine. Both will have two headers.

Well, yeah . . . . .

But we're comparing inline 4's vs. boxer 4's.

In my opinion, the few advantages of a boxer layout (self-balancing & lower center of gravity) don't outweigh the disadvantages of having to run two valvetrains, two intake manifolds, and two exhaust manifolds.

Not to mention the servicing difficulties . . . .

Two manifolds, blah blah blah. It's still the same amount of stuff as a V-shaped motor.

Not entirely. Only 1 intake manifold on a V engine.

Depends on the manifold's design. You could centermount a single manifold on a flat 4 or 6.

Wouldn't that kind of defeat the purpose of the boxer engine (lower center of gravity?). I don't really know. And it seems to me a center mounted intake manifold would be pretty restrictive. That's like 270 degrees of bends you'd have to deal with.

The more I think about it, the more I think a boxer 4 doesn't make sense. A flat 6, perhaps.

Not if the intake ports are on top and it exhausts out the bottom, which would be the most logical.
