    Rb26 would be a downgrade from what I understand. They are smaller than rb20's and 25's. I had a rb25 turbo I bought from someone on this forum and ran it for a week. Not much difference from the rb20 other than it takes a little longer to spool, and they have the same boost restrictions as the 20's meaning don't go past 14psi or they frag. Had to remove it cause it blew a bearing 7 days after I installed it, lost $300 on that one.

    How's it holding up at 15? I read they get sketchy after 14. I ran the 25 turbo at 10 when it blew on me.

    What about using the exhaust manifolds from a 26 with the turbos? Can they bolt on a 20 head?
    Aircraft are like cars in a way, you can never fix all the stupid crap, and you still have to deal with dum drivers(pilots)

    Skyline soon?!??

    No, I'm pretty sure they aren't compatible. Would be effin sweet if it could be done.

    Because? Just cause everyone else doesn't know as much as you about Skylines, you feel the need to flame? That is fail. The whole premise of these forums is to share and help those with less experience with these piece of **** cars, you got nothing constructive to say, keep your thoughts to yourself.
    Give your head a shake.

    And your numbers aren't that impressive, My Sentra SE-R Spec V ran mid to low 12's.
    Just cause you own a GTR doesn't mean you get to **** on the rest of us. Nuff said, just keep it friendly that's why we're here.
