RB25DET Header flanges

Post by **240Z TwinTurbo** » Tue Sep 28, 2004 10:17 am

I had some header flanges made for those folks who want to fab their own turbo header. These are 3/8" thick cold roll and are cnc laser cut.

I just had a batch of RB26 flanges completed and the RB25 flanges will be done tomorrow and I will then post a pic and give a final price.

How about stainless?

SS warps too easily...

try tig with 3/8" 304 stainless without preloading it, you'll see what i mean. as far as after welding wise, it's all said and done no warping after that, some if any.

Most header manufactures suggest that you use cold roll steel for the flange over SS because of thermal expansion. You will always get some degree of warpage when welding, but there are techniques that are used to draw heat out of the flange. You must typically use a large flat sander to have the flange decked when the header is complete. Here is the RB26DETT flange. I should have the RB25DET flange pic tomorrow.

Stainless steel does have the tendancy to pull ( warp ) more than mild or carbon steel. The reasoning behind this is because stainless is a stronger material, the molecules are much tighter within the material than in carbon and mild steels. But to not use stainless because of this simple vice would be misuse of a valuable resource. If you use the right steps during the process of welding a manifold/header, the flange will not warp at all. Both 1010 mild steel hot rolled and 1018 carbon steel cold rolled will warp a good amount themselves if not welded using the right process. Our company uses 1/2 inch thick 304L CNC cut flanges on our equal length manifold's ( http://www.protech-fabrication.com ) and have not had any issues with warping or shearing of the studs as some claim. When building a manifold or header it is always best to use similar metals as opposed to disimilar metals. When you use a mild or carbon steel flange on a stainless header with out coating it, one day you will pop your hood to see a rusted mess sitting atop a beautiful header, if it's welded properly during the delution process. Just food for thought.

just making sure: are the flanges for rb 20/25/26 have the same pattern?

Post by **74260zt** » Thu Oct 14, 2004 3:30 pm

25 and 26 are different....

*bump*

Sent you an email. Thanks for making all of these parts available to us.

I need a new metal header gasket for my RB20...anybody got a place where I can get one?

Thanks!

I am having some individual copper gaskets cut for this project and will post some pics when finished. I can make them available to those who need them. $80 is ridiculous just as paying $300 for a $170 rear sump RB20 oil pan is ridiculous.

Keep me informed. I was thinking of having some copper gaskets waterjetted at the local machine shop from a scanned manifold, but I wasn't sure if just a flat piece of copper would work, as stock gaskets have that raised ring around the ports that helps them seal better.

Are you going to make the intake manifold gasket also?

How much do you currently pay for them?
