I have received a few PM's and messages in regards to twin scroll/divided inlet collectors for T4 turbochargers, wondering how to make a true T4 divided collector. Well, I started working on the manifold for one of our shop's race cars today. We are using the Borg Warner S372R turbo, with twin TiAL gates. So far I only have the collector built, I took a few photos to share with all of you. I hope these help give you ideas. Im curious to see other T4 collectors anyone else has built, post them up if you have them!

 

looks F*cking good

what amps do you weld at?

 

Nice.

 

Set for 160A, pulsed

 

HOLY CRAP, that's sweet!

 

tell the truth...you don't really get a lot of PM's about these, you just wanted to show it off because it looks resickulous :-)

 

I think if theshodan sees the title of this thread he's gunna be angryyyy
It's divided housing

Nice welding thou

 

I can't imagine people having a hard time with these divided collectors cause they're cake versus a 4-1. I agree...I think you just wanted to be a show off.

 

Good job, Looks like a mint piece.

 

looks good..
what filler rods do you use for ss to ss and mild steal to ss?

 

The welds on that collector are really nice! That's some very clean work!

I have made a few, I basically make two 2-1's, then cut them at a slight angle, then crush them so they fit the opening, then weld ...

edit : Removed pics, don't wanna high jack!

 

Agtronic- That is exactly how I made it also, thanks for the post pics. RC000E-You're right, a 4-1 is much more difficult, but for most it is also much more common to build. I wanted to show something that is not an everyday piece. Honda_junk- 309L filler flange to pipe, 308L pipe to pipe

 

very nice....clean welds

 

what size is the filler rod?

 

I think he is using a 3/32 size filler rod for tube to flange and maybe a 1/16 filler rod on the tubing only for the tight spaces.

very nice welds, be nice if you could inform us on your set up specs.

 

VERY nice work SpeedFactory. I wish I could weld like that....

 

i wish i still had pics to post of mine but when i made my collector for my divided mani i made it just like a 4-1 but actually welded in a flat divider to separate the two sides. the way you guys have done it looks good and should work fine also, but i think with a divider between them, the two sides fit the holes in the flange a little better.

 

SFF, very nice work!

 

Not bad suka. Keep it up.

 

I was just messin with you man. Divided's are pretty nice to make versus 4-1's though, I must say.

Look at Agtronic with his little photo booth...hahahaha

 

How do you guys get down so close in the runners. do you just pull the tung out like over a inch??

 

That was supposed to go on the online store, that's why I have so many pics like that ... Not trying to be cool or nothin' ehehe ...

 

you'll have to change your name to markkool.

 

DisEpyon- yes, 3/32 filler for the flange to pipe, 1/16 for the pipe to pipe, and in some of the reallly tight spots, .035 308L filler. JDMCRX- major tungsten extension Got Wide- I've actually done that too, I had it all mocked up but I wasn't happy with the way it fit together versus this type, but I didn't spend much time on it. That's awesome someone else did that too! hahaha

 

I've got a question for the fab guru.

I'm running a Weldcraft CS310 water-cooled torch (this one)
http://cgi.ebay.com/Miller-Weldcraft...18124005r22436
on my Miller, off a foot control. I'm tied to the weld table and want to get out and under stuff.

What would you recommend for a torch and trigger to get away from the table. There's so much stuff out there, that frankly, I'm not sure what to get. Do you have a favorite or a "go to" torch you find yourself using more often?

Any help appreciated.
