Hey guys, I already posted this in the welding/fabrication section and no response so im hoping any of you might be able to help. Im looking for any specs or dimensions for a exhaust manifold flange for the f23 vtec block. Im planning on making a homemade manifold for a turbo application but need the proper dimensions of the flange including a sugestion on the thickness of the material i should use. I plan on making all the tubes and tig welding it all. Any info would be greatly appriciated

 

header gasket would be a start...

check your post in the welding/fab forum i answered it there . weirracing makes an f22bx header flange and the f22bx and f23 have the same header flange.
