BMW 326rb build thread...

[wannabe-silvia]

wow guy amzing build, where u go to school and learn all this shit form??

[ctnewman]

i'm a mechanical engineer.

I went to University at buffalo (though all my cad was learned on my own/at work...)

[sepulchral]

m.e. in the making WVU right here

[ctnewman]

So i took the patterns i made, cut them out, wrapped them around the pipe (1 1/2 sch 10 304SS) took them to a bandsaw, then a massive belt sander, tacked them all together with a mig (309SS wire) and here is the result. I also drilled and tapped my 1/2 T3 Flange (will be studded)

[Ninjabread]

Nice clean merge. Is it just me or does the flange looks bent on the first picture?

[projekt_s13]

wow nice, wish i could weld

it's warped about 1/32, i don't know why it looks so bowed, But, i made it out of 1/2 304SS, so i can just mill it flat once it's all welded.

Awesome build dude, I found a few pics from a shops Z32 RB26 build.




^^ Hope these help in your manifold making.

[ctnewman]

^^, thanks, i think mine is more or less set. Nice clutch on that. I had a exedy triple plate for my last R32 RB, but never installed it then sold the whole thing. wish i hadn't, sold a brand new 1300 dollar clutch for 400 bucks.

[fromxtor]

I mainly posted those pics becuase I didnt see a wastegate port on yours. Looks awesome keep on keepin on.

damn dude, I did 4 years of cad/cam design with cnc machining in high school, but I've never seen any private party do something this awesome. Good work man!

[ctnewman]

valentine's and a few other things slowed me up...

Here is what i did tonight:

[Ninjabread]

That manifold is pretty donkin!

Won't that manifold boost creep? It doesn't look like it promotes easy gas flow to the wastegate.

It isn't bad, really, most of the time the WG is mounted perpendicular to the collector center plane, they have done this, but in 2 locations. In fact, I am willing to bet it does not boost creep at all...



This picture shows it a little better...

I may have boost creep at lower boost levels... I plan on running a 38MM WG, but i am running 20 psi... I may use a larger pipe and neck it down so that in case it creeps, I can purchase a 44mm and just weld on a new flange...

[ctnewman]

mmm, sexy.

weld what's visible, cut runners off the collector and flange. weld runners on bench. weld pipes back on. All whilst backpurging with argon.

[bardabe]

man that looks nice bro. keep up the good work!

[chibo]

Holy shit, that thing is art.

[Reos77]

Are you planning to tig weld those pipes? From the pic it looks like you tacked it all with a mig. There is also product named por 15 used to fix rust. It is a little expensive but many car builders recommend it. I don't know if you answerd this question already, but are you going to weld in those patch panels or just leave them tacked in? I suggest that you use some weld through primer for corrosion protection on the bare metal. I think the project looks great, keep up the good work.

Pipes will be tig welded. You can see that the collector already has been.

I used a comparable product to por15, there are a few pics of it about a page back.

I am only leaving the panels tacked in, because the car is getting a 10+ point cage that ties to the main frame in 6 locations and to all 4 strut towers. I will seam fill them to prevent any water intrusion.

[SimpleS14]

Damn that is some awesome work, you should have a side job custom fabbing parts.

[ctnewman]

put the tranny back in and test fit the exhaust. Fit perfectly.

[sliEighty]

just spent 30 min of my time looking at this thread thanks man haha looks sick

[PoorMans180SX]

I've been lurking on this thread for weeks. Uber cool man, love the idea and the work.

[Slidin240Wayz]

Is that a turbo that helps prevent surge?
