rb25/20/26 turbo exhaust manifold.

ive heard that the rb exhaust manifolds are somewhat universal, and if i found a nice turbo mani. for an rb20 i could use it on my rb25, or i could use the twin turbo rb26 mani. on an rb20 if i really wanted. can anyone actually CONFIRM that this is true to any level? it would make finding one much easier on a hybrid swap for my s13.

20 to 25 and 25 to 20. 26 is diffrent from the both not sure how I didn't get a chance to line up the gaskets. Most likely the ports are bigger and the flange won't line up. Hope that helps.
