custom intake manifold?

i was thinking that with a motor that likes high rpm power and with a front mount inter cooler on a t78 that my motor might want to ahve a shorter path from the turbo to the ports. so would a custom short runner intake be possible? has anyone ever made one? is it worth it on a street driven car that i plan to frequently run 24psi on? i realize that more botom end power may be lost as thats my previous expierience on v8's...

I've got a custom built upper on my T-II. It uses a 75mm Mustang throttlebody with one large plenum. Low end suffers over the stock setup and is a little less drivable on the street but there is more power in the midrange on up. It's only a toy car for me anyways so I don't mind.

is this hard to do? i guess i could go the ghetto home way and just buy a throttle body and some aluminum stock and make a rectangular box with the throttle body on the end and create a base for it? anyoen have a stencil of the ports of the lower intake so i can make the ports match?

You could go buy an intake gasket. That would be what you would want to port match to, right. Besides, you'll probably need one anyway.

I made my flanges off of tracings of the gaskets. I ordered the aluminum tubing from Burns Stainless. The throttlebody came from Summit Racing and my friend welded it together. It's not cheap or easy if you've never done it before.
