My brother and I are getting a new set of SU's for our 240, and have a question regarding which manifold to use with the carbs. I know 240's came with n-46, e-88, and n33 manifold at various points in it's production. I've read the general internet conjecture about these manifolds performance, as well as the n-36 manifold that came on the 260z's. We have ALL of these manifolds available in our shop to use. I'm skeptical that there will be a substantial difference in performance between them, but curious what the wisened community here feels on the subject. I.E. which manifold would you guys use?? The engine we bought our car with (an ITS 240) is to our knowledge bone stock. Also i'm curious what needles you guys are running, and if you are just using the standard 20w oil in the dampners or if you might have any other advice regarding the carbs. Thank you in advance for your comments.
