I've been busy with some other engine builds and have also been working on my tubing bender and my shop. I did manage to sneak in a little time on the oil pan. I welded in the three scavenge tubes and started to grind down all the welds and blend them in.

I measured up and cut the rear baffle.....

Then I notched it to clear the main studs and nuts....

With the K-member and the pan together enough to do some fit checking, the last part of that fitment component was the headers. I ordered a cheap big block chevy header kit from Jegs, used a set of flanges that I had, and set out to build a set. My buddy made some transitions for me that matched the ports. I used those and started adding tubes.
Last tube.....
I like the way these ended up, even if they are just a tad too high in the chassis.
The last part was to weld on the collector. After that I added a 3-1/2" to 3" transition. We'll go from 3" directly into the turbo.
I had decided I'd better check the fit up on the whole mess so I bolted it all in the car.

There's a ton of room between the pan and K-member and even more so between the header and the K-member. So much so, that I'm going to raise the K-member center piece an inch.

The header clears the frame and also the lower control arm mount area on the K-member. Dodged that bullet!

You can see all the room in this shot. Moving the center beam up an inch on the K-member really solves a lot of problems with rack mounting by bringing the rack into the same plane as the lower control arm pivot for minimum bump steer. It also gives me another inch of ground clearance.

I trimmed off the header end and fitted a v-band flange on it. Then I put in the first elbow. This elbow goes through the gap shown above in front of the K-member and behind the radiator yoke. It fits so tight to the radiator yoke that I'll have to go with a shorter radiator to fit above the elbows. Not a big deal since I planned on running an aftermarket unit in the first place.

This 90 degree elbow turns sideways out and will immediately connect to another 90 that turns up vertically. That one will go right into the bottom of the turbo and the waste gate will be on the outside of that elbow.
