Headers for my 2.5 TBI Dakota

[Martin]

I was wondering if anybody knows of a place I can get headers for my '94 Dakota 2.5 tbi. Or of a place that could make them cheaply. Or would it be posible to cut up a header for a car and weld a few more bends in it.

None on the Dakota mailing lists or net I see.

Probably no gains to be had, TBI manifolds apear pretty free flowing
less maybe cutting the collector off and making bigger one.

From what I have read the TBI manifold flow sucks and is the main limiting factor in why these engines only make 100 hp stock. So I am debating on weather to have it ported or swap in a modified MPI turbo intake manifold. After that I want headers to make use of added flow of the intake but I have yet to find any.
Oh and Russ that is one sweet truck your building there I wanted to build turbo dakota to but now I want to see how much hp I can make NA. Then mabe someday when i have the funds stick in a 8 valve turbo engine.

I ran into this problem so I made my own. I bought the head flange from Headman headers for $20, bought a collector at a local speed shop then using my mandrel roll cage bender, made the header. On my clayton dyno I gained 15hp over the stock cast manifold (this was on a modified engine being used in a circle track Pro4 car)
