Rb26 Exhaust Manifolds

[slo240]

first of all, im new here so hi to all...

i live in the us where they dont have skylines, but i drive a 240sx, and have had several turbod cars so thats nothing new.

i tried searching so please try not to be to harsh, as the topis says, do the rb26 exhaust manifolds fit on the rb25 head, id like to have the quick spool of 2 smaller turbos, with a max hp of about 350, im not sure how that compares to kw?? any useful info will be great

<{POST_SNAPBACK}>

no they don't....bolt pattern is different.

thank you, i just found the answer myself aswell...

An adaptor plate is easy as most bolt holes are the same.

I have an RB25 in at the moment with GTR manifolds and twin 25/30s and all is well.

You can have the 2 unmatched manifold flanges cut off and welded on to suit as I did, then a little work with the die grinder to port match. Then the rest of the exhaust system off a GTR just bolts straight to an RB25 in the R33 Skyline.

i have an adaptor/spacer plate/plates on my RB20 to allow me to use the RB26 exhaust manifolds along with the twin turbo setup

it's doable, just depends on how much patience you have and how deep your pockets are (might not even be that expensive anymore, or for the RB25 anyway)
