Do the 25 & 26 share the same runner alignment???

[meet07]

im curious if a RB26 exhaust manifold can be purchased and fabbed to fit a RB25?? Meaning the runner alignment. I know the fange is slightly diffrent.

thanx

[eh?]

I personally have not seen it but I know Apexi made an exhaust manifold that fit the RB25/20/26. So.... i would assume so..

20/25/26 share the same exhaust runner alignment.

Proof?

Full-Race manfifold, fits rb25 and rb26.

thus, runners; RB25 = RB26

HKS cast manifold, fits rb25 and rb20.

thus, runners; RB25 = Rb20

Concluding RB20,25,26 uses the same runner alignment.

i try to sound like i did research.

it might be worth the money to take the aftermarket 26 twin turbo manifold and cut/reweld on the 25 flanges to make a twin setup.
