Hey guys, trying to do a diy manifold, and I'm just wondering what schedule piping to use for my turbo manifold. Where should I get the piping as well?

 

If you are looking for the full race style deal try http://www.mcmaster.com try schedule 40 or schedule 10 thick material weighs a ton but way easier to weld


If you would like to go more towards what race cars run and you have some good fabrication skills use 16 ga. 321 stainless steel.

available from us and numerous others

 

Thanks for the quick reply!
so is the schedule 40 lighter than the sched. 10?

 

oh hell i dunno whichever one is the thinner wall thickness its all plumbers material too me

 

I have a better idea for you. Go on ebay, find a cheap SSAC manifold. Chop off the "collector" buy/make a decent 4-1 collector out of 304 16 gauge Stainless Steel(costs about $10 for a foot i believe. you will probably need about 18")

Weld the new real collector to the SSAC manifold and fabricate some simple braces off the block.

I will bet $5 it out performs any plumbing piping manifold in everyway, shape, and form for a fraction of the cost.

this also is dependent if your collector sucks or not, but if you a decent job, it will work wonders and save you a bundle.

Remember, turbo manifolds are made to transfer the exhaust gas to the turbo in most efficent way, not support 30-50lbs of dead weight

 

Well said will!

except i would just fab the whole thing out of 304 16g

Theoretically speaking SSAC manifolds are made out of SS304. I believe they are 16 gauge, i couldnt swear on it since ive never actually had one in my hands, but i couldn't imagine them using any thinner of a material.

The only reason i say do it my way is because bends in SS304 is just so ridiculous expensive that you will spend $200-250 on the bends ATLEAST then you have another $80 on flanges, **** ebay SSAC=$50 sometimes. put a collector on and you are golden.

but then again, this is honda-tech so we need turbo manifolds to suport our T4 turbos which are on our AC compatible street cars. Full boost of 10psi at 6500rpm y0!

Other way around, sch 10 is thinner wall. The McMaster catalogue has a chart and .dxf files are available online.
