Turbo Manifold Fabrication

[Bsa]

So I'm going to make a custom high mount manifold has anyone got tips on pipe size ect. I know I should run equal length runners but its not possible as I'm very limited for where I want the turbo to sit any help will be great throw me some ideas

I'm undergoing the same task ATM blake .

Although im makeing a Low mount similar to Nissans

If u look at te factory Nissan there runners aren't even length !

Also tips I've been given is after its all tacked cut the runners back of and weld the flange it's a lot easier to get a neat weld there

Weld the colecter first when u make it

Also when welding the head flange bolt it down to something Iike 100x100x5 should help prevent warping

I'm makin mine out of 36nb pipe that is 3mm wall 304 stainless

You can buy the merger and the collector which I will be doing comes with flange and all that's the hardest iv heard and they look smick stainless ay sounds good as I'll make my down pipe stainless. How much where materials if you don't mind me asking

[BOOZTJUNKEY]

Man I got the material thru my work and was under 100 cause boss loves me hahahah I have 1 1/2 meters of straight and 9 bends man honestly it would prob be about 200 roulghly

If I had to pay ful price probably woulda went mild there is a company on eBay that sell steamy pipe bends u get like 20 for 60 bucks hahahah then get pipe to suit it

And I have seen them merges on eBay for 90 bucks man they look ok just depends on wall thickness

I have a good supplier so I should be alright can't put boring black on tge BMW has to look shiny for atleast start up haha

[BOOZTJUNKEY]

Hahahah yeah fair enough my material is 2b anyways so it's not gunna b shiny anyways .

But I am gunna get it hpc coated instead of polishing because it doesn't take long for it to get that yuck tainted stainless look
