ALMOST DONE!!!!!!!

Ray (statepolice! here on the boards) did all the fitup and most all deisgn. Ill be doing the welding next week when we get more gas. Just needs final welding, its all tacked together right now. Equal Length 321 Stainless 16g Tubular Manifold for RB26Z32 car. All material from http://www.burnsstainless.com including the collectors.












Each primary is 23" long.


This is the FIRST tubular manifold weve done. Needless to say we are very pleased with the outcome thus far.

 

Wow. The downpipe is going to be a bitch.

Its hard to tell by the angle of those pics but we have room for a 4" downpipe no problem. This application will be using a 3.5" however.

 

that bitch is gonna hold some heat looks awesome tho

 

wild

wheres the WG gonna be located? or is it an internal gate?

 

We know heat in the engine bay will be an issue with this car. It will have a large Cowel/Vented hood to clear the Engine and turbo so hopefully that will help.

The Wastegate will be locatedright by the #3 runner with a 2-1 collector coming off the 2 Burns collectors.

Thanks for the compliments guys!!!!

 

You used flux-core to tack up a stainless exhaust? I'm guessing that's just mild steel flux-core, in which case have fun with the rust. Way to go spending an easy $800 or so when you're going to end up with the same results as if you used all mild steel.

 

Been a while The exhaust manifold looks great. Cant wait to see it finished.

What?????


Its stainless wire in our Miller 135 MIG w/ gas.

0x64... it has been awhile buddy

 

Relocate the power transistor on that POS engine. They overheat with the stock manis easy enough.

 

What gas mixture were you using to tach the runners? I'm also curious in general how people are measuring their runners to know that they are equal length. (Follow the inside or outside of the bends?)

Anyways, looks like the manifold has some nice potential once it's all welded up. Let us know the spool characteristics of the turbo then if you could.

 

wow that looks awsome i wonder how long that took to make

 

You should be following the centerline of the bends or taking the inside and outside and finding the average.


Manifold looks great nice collectors

 

Casey your so smart!Yep that's the way you do it.Its nice to see full equal length turbo manifolds.One thing.WHY DID YOU TACK IT WITH A WIRE FEED?
You know how to weld around ALL the tubes right?Pick one of the tubes.And weld it up as much as you can.Weld it to the flange also.Now that ,that one won't break off .Cut the tacks at the flange on all the rest of them.And take them off.Then weld em up.Using the one that you welded on as an index for all the rest.And it will fall into place.Wire feeds are for making JIGS not headers.LOL
looks good so far.

 

are you using a twin scroll turbo?

 

Yes, as it has been state3d follow the CL of the piping.

Casey, We were hoping youd see this..... after all the tech questions we bothered you with im glad you got to see where they went. Thanks again!!!!

Again guys.... we are not MIGing this entire manifold. We used a wire feed(w/ stainless wire) to tack all the pipes together as we had to make the manifold in the car for clearnace reasons. All those MIG tacks will be broken and grinded off after we scribe the location of the pipes and clean and prep for final TIG welding.

We used 100% argon on the MIG for tacks, however it isnt the most consitent machine.

The Turbo we are using is a GT35R .82AR


thanks again for the contructive critisim guys. This being our first tubular manifold, we know we still have alot to learn.

 

looks good. Clean up that engine bay though . Those collectors do look very nice, burns stainless.

That turbo and the .82a/r turbine is a hair laggy on the shop car at where I work, but it should be perfect for your RB26 motor. Going with the t04s ported shroud compressor housing too?

 

ITs a standard T04S compressor cover. No frills. We beleive with the 2.6 displacement and hopefully some help from this manifold this turbo will spool pretty quick on this car. The power goal is 500+whp on 93 octane pump gas..... well see how it goes.

 

i found a new appreciation for RB cars over the weekend....a friend of mine now has an R32 that's getting a single....and it's going to be EFFING NASTY....allready has nismo twin plate and nismo gears, with andrew's racing wheels too...

nice mani!

 

I've always wondered about this, do people use filler when tigging 16g metal?

 

We do

 

yep, after practicing with the PLENTY of straight material we have left over, ive decided I need to use filler for this. Fusing leaves too much undercut and/ or not enough penetration. With the filler i can move very slow on low amps and dip in the filler as i go. Atleast i personally feel more comfortable using filler.

 

Here is one that I did a couple weeks ago.Only fused it.If you get the purge right ,it will push the weld out ,not in.People that do sanitary tubing for food processing and Creameries don't use filler rod eather.They just fuse it.And it comes out perfect.
You can do it any way you want .I'm just sharing how I would do it.I'm sure it's going to come out fine however you do it anyway.
One thing to remember"You can tell a welder ,By the sound of his grinder" LOL

very nice brian, looks very good is person. forgot to tell you, that damn dump didnt fit i suck at measuring
