    Default bbc turbo manifold choices?

    1st off I know pretty much zero about turbo's. I've seen some log style exaust manifolds and some custom made dry deals. I dunno, let's see your turbo's. Btw I'm going blow through.(I hope)lol, unless I go broke.

    Given the context of the question... I'd say he's asking about exhaust manifolds. Curious myself as I plan on using logs.

    Turbo exhaust manifold choices for a BBC are going to be real limited.
    Either you go with a set of old Gale Banks or Gentry manifolds and be limited to squeeky little dune buggy turbos,
    Or you can alter a set of CMI stainless manifolds (or similar) like Superdave did,
    Or you have to make your own from scratch like I did. And it's a lot of work.

    Old Banks (not made any more and not real efficient by comparison to below)
    Gentry (Brummett)
    Old Race Aero (not sure of Brummett is making these still)
    CMI Header type
    Other center rise type but you'd have to adapt them to turbos

    Or a set of shortys and fab up the flanges. I have made some headers for these deals. Equal lenght and all that jaz isnt as inportant cause there is back presure anyways. H20TRB0 I can make you a set.

    Thanks guys. Hey 71 maybe we should work out a deal for some cyl. heads. Is a turbo timer, and timing retard or some level of boost control a must for a boat? Or is that more of a gray area?

    We use the digital msd stuff. Manual boost controler. Timing is done through the msd and the power valves are also run with the msd. Lets you turn on the fuel when you need it. Also lets you data log. You can go back and see what it was doing when you were cruising, wot, exc.

    You can use any water cooled exh. man. like Imco Powerflows etc. and make a transition block to accept whatever turbo is going on top. This transition piece can be made to accept wastegates, probes for egt. o2 sensors etc. I will be doing this in the future and will start a thread after Barry " obnoxious001" assembles the 622cu alum. BBC. I am going to use some old Drake alum. manifolds that have 2" individual runners that should not be too restrictive.

    Very nice! What turbos are you using? Still undecided and doing my home work.
    Any suggestions would be helpful.

    Why not consider using a late manifold style that you can at least buy a replacement for if you smoke one (yes it does happen)... Just a thought.
