Mark,
I was checking Speed TV's schedule for F1 preview shows and saw they have a feature on the 240 Z coming up soon.

SMS...When done, it will be a full 3" mandrel exhaust from the turbo back.
I'll make some more progress over the next two days.
As you folks may have noticed, I"m a dog person. Don't care for cats.

UPS just dropped off the 3" ID, 90 degree, 3" radius bend. I need for the first turn in the downpipe.
After shortening up one of the legs, it will FIT! :woot:

Hugo Schekter, Tomas Schekter's brother, and related to Jaki and Toby, etc, has posted up a ton of picks from a Top Gear filming event.

How about a few more pics of what is in process?
Here's the middle section with the S-Bend. You can see the OEM version sitting beside it.
The existing 3" rear section.
The whole section so far
Now if the bend I need for the downpipe would actually show up today, I can get on with that portion tomorrow.

The middle section has been fitted, tacked and cut to fit so it clears underneath and mates to the rear section. Joints need to be completely welded and the v-band flanges attached to the back of the middle and to the rear section. Then those two are done.
Then onto making the downpipe. The delivery of the part I need for that section has been delayed until Monday. Its sitting in town at UPS, but no way to get it on the weekend. I had ordered it from Summit Racing in OH. They are so close that I always get deliveries next day. Turns out they shipped this part from a warehouse in GA.

They really need some better sledges. Those just weren't getting the job done.
Was it me, or were they all wearing hardhats, but no eye protection?

The exhaust will consist of 3 sections:
1) Downpipe = two 90 degree bends
2) Middle = long section with S bend in center
3) Rear = the existing 3" CAT back set-up I've had for years.
Each section will be connected by v-band flanges and clamps.
Today, I cut and fit the middle piece sections. This is made up of a straight, then S bend, then straight back to rear section. They are ready to be tacked together. I should be able to go ahead and have them mated to the rear section. I left the front section long so I have extra for fitting the downpipe.
Waiting for a 3" radius 3"OD mandrel bend. According to tracking, will be here Friday. This should fit the space I have. Keeping my fingers crossed. Both the 90 & 180 degree 3" bends I have, turned out to be a 6" radius. I used the 180 to make the S bend section. The center section of that may come in useful on the downpipe to give it a bit of a snake to clear everything and mate to the center+rear sections.
Sections will be tacked to make sure it all fits, then when happy, weld them up pretty.

Turbo is back in the car.
First challenge: Larger T4 side runs into some interference with the PCV with where I planned to have it clocked. After playing with it more, it looks like if I clock it to a different spot, I can shorten my IC pipe by some 1.5-2.0 feet and remove one silicon coupler from the entire line. Means I need another 90 degree silicon coupler to make it happen. So I need to return one piece of tubing that won't be needed and order the coupler.
Second challenge: I hoped to go with a 90 degree 3.0" mandrel bend right off the turbo. Unfortunately, not enough space to make it happen since the radius is just too large on a 3". Now looking to find a 2.75" or even a 2.5" with a small radius to fit into the space. Once it makes the turn, flair it to 3" for the rest of the run.

I'll have to try to find that to record. Thanks for the heads up!

Here is the new and improved AFM to Turbo piping.
The stainless steel section on the left has the needed vacuum fits to run stock lines. At a future date, these can easily be removed and plugged. With MegaSquirt and Spark, an open source engine management tool, these lines are not needed.
There is a silicon hump connector that will allow some play where is attaches to the Air Flow Meter. That will accommodate the rocking of the engine on its motor mounts. The AFM is mounted via rubber mounts that will also accommodate some slight movement.
Note the larger diameter = MORE AIR FLOW into the turbo!
Now that this part is done, I can now install the turbo, attach the oil feed line and bolt a few other parts back onto the engine.
One hick-up though. One of the exhaust tubes I have is actually 0.25" SMALLER than I can use. Oh well, at least it was free to me, so no money wasted on that part. It means I need to order the correct part. No, these mandrel bend tubings are not available locally. Grrr. That's OK, I have other sections I can work on for the moment.
