Turbo intake manifold 4.0
So, I own a gremlin that I plan to drop a turbo'd 4.0 in someday (when the amount of money I make isn't so little) and I want to fabricate and intake better than the stock one.
Is there any reason that relocating the throttle body to the front like this would not work?

Would air be distributed evenly enough to the cylinders? Seems like #1 and #6 might receive significantly different supplies of air with such a differing distance to the intake, but then again I don't exactly see how that intake will be functioning with a turbo, so maybe it won't matter?

*nods contemplatively*
I do love the idea, and because it is for a Gremlin, no one can try to shut the discussion down saying that turbos are impractical for offroading as if everyone with an XJ is automatically an offroader.
My girlfriend's dream car is a Gremlin, and out ideal situation would be to find a solid roller (because the budget is tight right now) that I could later drop an engine into. Given my expertise, a Jeep 4.0 would be a very likely candidate, and I love the idea of a turbo'd 4.0 in a Gremlin.

Here is one I made for a VW some years ago. The manifold flange was already made. I make intercoolers and charge pipes for a few turbo guys these days but intakes don't make much of a performance difference.

Any manifold will work since you will be pressurizing the air coming in. If u were to take the TB opening an shift it to the outside edge of the stock it would leave the long runners to aid in velocity in higher rpms an help keep a balance in airflow between the cylinders.

The greedy intake i had on my rb25 ran a little lean on the two end cylinders.The spark plugs on both cylinders told the tell.You could do like i seen on some 12 valve cummins a log manifold with two inlets spaced about even apart from each other.I know a diesel don't have a throttle body but air flow is still air flow.
