Pro Stock driver and fabricator extraordinaire Gene Wilson has a twin turbocharged dohc 4.6 in a 4 door focus. Talk about your sleepers... that thing takes the cake.

As far as headers go for the swap, looks like with the limited space, the mid length that come with the kit would be ideal....On with the project!

I tried a set of longtubes not sure what kind but it would not clear the damn steering knuckle. Anyone around dfw have a set of longtubes for a fox I could use to test fit. I will leave a deposit on them so i can see what fits. Here's the steering knuckle.

I test fit a pair of Pacesetter LS1 longtubes in my car, and they almost fit perfectly. The only thing I would have needed to do to make them fit in as-is would be to lower the engine about another 3/4" or so.

What kind of mods did you have to do? I am actually trying to fit my headers now, and am not having much luck, I'm using mac 1 3/4 long tubes in a 95 with a 4.6 tubular k-member. any help would be great.

tHE DRIVERS SIDE I HAD NO PROBLEM JUST SLIGHT ADJMENTS BEFORE I COULD WELD BUT THE PASSENGER SIDE I HAD TO TRIM THE K MEMBER AT THE BOTTOM WHERE THE 2 BOLTS ARE I HAD TO CUT IT TO WHERE THERE WAS ONLY 1 BOLT AND I HAD TO MOVE THE THIRD PIPE ON THE HEADER I CUT 1/2 INCH OUT OF IT WHERE THE PIPE COMES DOWN AND THEN IT TURNS BACK THAT IS WHERE I CUT OUT THE 1/2 INCH RIGHT AFTER THAT BEND. AND I HAD TO SLIGHTLY FLATTEN THE TUBE THAT IS RIGHT NEXT TO THE FRAME RAIL

from what i'm reading i think using a set of pace setters and maybe tilting the engine back a bit would be the easiest way?
to the guys that used pace setters , do you think they would fit if the motor was tilted back a bit ( if so how much tilt is needed?)
will the oil pan clear the k-member ( or will there other issues) if the motor is lowered about an inch?

I didn't know the motor mounts on the AJE where adjustable?
so just to clarify, if i use pace setter headers, 4.6 engine mounts, and a AJE k member i won't have any issues?

They're not adjustable, but there's nothing stopping me from cutting and welding the mount perches ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
I'm going to open up some dialog with a couple header manufacturers (starting with LS1Tech sponsors of course), and see if this is something they'd like to persue offering.

here's another question for ya! AJE offeres a dropped steering rack option ( i think it was 1.5) , will this help any with the steering shaft hitting the header issue?
