Here is some pics and videos of what I've been working on. The amature home movies should give you a laugh. I said the turbine exducer is 85mm by mistake. We know, of course, its an 88 with a 1.32 ar.

I also put a little bridge in the wastegate spacer to stiffen it, so hopefully it won't leak.
I did the math on the opening and its got an area of about 0.9 sq. in.
The wastegate inlet is 1.5" dia for an area of about 1.75 sq in. Hopefully the gate will still do something. If the boost does creep up too much, I'll have to change it.

Pedestal angle iron is 1 1/2" with three holes: 2 @ 3/8" for mounting and about 7/8" for the drain. All on 1 inch centres. The angle fits with just a little grinding.

Looking good buddy, I can't wait to see how it working on the truck.

 

The s362 and location for s475. 88mm turbine and 75mm compressor. max flow of about 98lbs per min.

 

So how far are you into the build buddy? Looks like you'll need to add a oil drain into the oil pan/block for the primary. I'm curious to see how everything turns out for ya.

 

The package from race part solutions finally came in after going back and forth between Edmonton, Calgary and Winnipeg. Took a month but Race Part solutions paid the 50 clams brokers fee after it was sent by UPS by mistake.

 

Truck's in Mac so don't get to work on it often. Install is planned for Aug. if Kev can accomodate it. What you see is what's been done!
Yep.

For the oil drain I scoped out the location for the hole in the pan by pulling Kevin's mangled pan off his block. The pick up tube is right below where the pan connects to the block, so I have to stay down a couple of inches from the top when drilling. Anywhere after the second bolt back is a ok to drill.
I just bought a foot of -12 braided steel line and a 3/4 NPT hose barb fitting for the turbo. That line is rated to 230* C so I am hoping it won't melt inside since it sits right next to the turbine housing. If it looks like it's getting too hot, I can just screw in a 3" nipple to extend the attachment away. Thoughts?

 

The block is slightly different between the storm block and the CR. The oil pick-up is also slightly different. CR are bigger.

I wouldn't put a hole to low/deep down into the pan. You should try to stay above the oil level.

 

and mounted the B1 on top.

 

Looks good, you are making progress, did you put the wastegate spacer on before you put the turbo back on after you flipped the mani?

 

Just what I typically do, is I start first by building the primary turbo brace. Everything should be fitted around and to the primary. If you work from secondary to primary, you have to do more adjustments to you hot pipe.

About a few more hours you should be run the new set-up buddy, looking good.

 

Yep Brett, there's a spacer in there.
Here is some more pics what it did today.
One shot of the RG for you Brett!

 

Good work buddy, keep the pics coming... can't wait to see how it turns out for ya.

 

What is the best way Mike, Brett, et. al.:
Step1 -Primary pedestal
Step 2- hot pipe??
Step 3- cold pipe?
Step 3- Intake?
Step 4- exhaust.

I am a little confused about what you meant Mike when you said working from the primary to the secondary is better.

Might take YOU a few hours. I see lots of hours of fitting and finishing

 

Steve I love the RG, thanks for the pic.

Yes your order of operations is how I normally do it.

-Mount primary: Test hang oil feed and drain, make sure there are no issues, rarely do I install them at that point though, also test first elbow of down pipe to make sure this isn't going to bite you later.

-Mount secondary (in your case just flip manifold, and reattach)

-Build Hot pipe between secondary and primary including external gate stuff

-Build cold pipe between turbo's

-Build intake for primary, or shove filter right onto primary

-Build charge pipe from secondary to intercooler

-Build down pipe and connect to exhaust

-Install previously test fitted oil lines

-Connect all previously built pieces

-Leak check system with compressed air

-Start truck and let idle for ~5min make sure there are no oil leaks, and nothing is rubbing

-Go for test drive and look like this guy:

 

I would install the 5in exhaust on the primary prior to welding the hot pipe. Don't tighten down the primary brace until the exhaust is on. Then tighten up the brace. If you don't install the exhaust, you really don't know what position the primary will be in. 5in exhaust down pipe will be big stuff. Might have to trim the cab flange some with the saber saw...

A few more hours Steve and you done, if you have all the parts...

but I thought nobody here at DTR wants to talk about twins these days.... Remember stock is cool...
