I am doing a different NB midpipe and axle back. I honestly think the piping around the diff will be easier on the NB, it has the single piece axles. The one thing I am worried about is the hangers for the muffler. It is a big piece and there are only 3 hangers on the back of the NB. I had to add an additional hanger on my NA to make it balance decently by itself.

It balances OK. Also, I'm not sure it much heavier than the stock one with all the baffles.
*edit* or are you concerned with when the mid pipe is removed because of how far forward the joint is?

My previous setup was very similar. I covered the heater lines in high heat sleeving from WireCare.com and never had an issue.

each of the exhausts we've fabricated so far it was a pain to keep everything away from each other in that specific location

Your V-band outlet for churbo- I have seen these on the eBay, and I am concerned about the wastegate opening up to a flat section where the gas has to flow down at a right angle. is this issue?
Your exhaust pipe materials, what are they?
Do you have a list of what you bought, IE how much straight pipe, what sort of bends etc....
Clockin' lots of dollars (and the trubo) what dictated the position on the log, both front to back, and up-down as it does the polar rotation around the center of the log itself?
I've bought the flanges and the els. Looks like the els will need to be nipped a bit at the ends so they all line up in their nice little holes on the flange...

16 gauge aluminized steel for all the pipes.
I had the trim both the weld els and tees down to fit the BP flange.

On the NA I remove the coolant hose from the metal line. Then bolted the line to the block, and beat on it with a hammer. Cut the coolant line slightly, reattached the line, and now there is clearance. I suspect the same process can be done on a NB with no problem.

This is my first time building a manifold. I'm using a 13g turbo off of an auto 1g dsm. I ordered the manifold "kit" from mazworx. The flange for the head is basically flat stock, so it has been through the surface grinder. The inlet flange for the turbo was rougher than a cob. I ended up milling all 4 sides, surface grinding both faces, boring the center hole and milling the radius in it so it will sit tighter against the manifold. The turbo outlet flange had 3 staggered passes on the mating surfaces, so it had a couple of steps in it. I am using an external wastegate, so I made a plug for the wastegate hole, welded it in place, milled it flat and then put it on the surface grinder.
