hellraiser Posted May 19, 2005 Share Posted May 19, 2005 o.k after looking around in the few places that i could, i cant seen to find a rb26 head to put on the rb25 block so that i could have twin t's on it. so now my question is can i put the twins on the rb 25 head, are the 26 and 25 manifolds interchangeable like on the 240z's ?and would it make any sense and more power to do this other than that it would look hella good!!

stony Posted May 21, 2005 Share Posted May 21, 2005 No you cant you will have to make a custom manifold as the stud pattern between the rb25 and rb26 are different. and for that matter the rb26 head is not a bolt on swap either. Quote Link to comment Share on other sites More sharing options...

Dont take this the wrong way, but i dont see what the big deal is, with wanting to run twins, most jap power upgrades for the RB26 (& similar engines) go to a large single anyway, this would make for a far simpler set up with plumbling etc as well, far less expensive iniatially and on going, as only one turbo and one gate as opposed to two of each. Even if you are concerned about lag with a large single, this can be greatly reduced with the use of modern type turbos such as a correctly sized GT--R from garrett with their BB centres etc. As a side note, i also remember a great statement made by Corky Bell in his book "Maximin Boost" "If you have no lag, you also have no surge of big power to look forward to either" or something like that. As if the turbo is sized so small as to have no noticable lag, it will also be so small that it will drastically restrict power up top. A twin high mount set up sure does look mean, but hey, is it all really worth it? Just my 2 cents & personal opinion, but hey we are all different eh.

Cool man, just trying to save you some hassles. I am just in the process of ordering a GT35R and a Tial 44mm Gate, for my RB30DE Quote Link to comment Share on other sites More sharing options...
