    10mm is the way to go. just be aware if you're going to wrap the manifolds to keep it to one wrap otherwise it gets too tight to get the nut on the stud lol. i ran into this with my 8mm studs even.

    I won't wrap the manifolds, but i will be getting them Ceramic Coated.

    tmbg, I Live in New Zealand and the flanges come from the main exhaust supplies wholesale outfit called AUTOBEND.

    I was going to get some cnc cut but then i realized they were cheap and in stock.

    If anybody would like the CAD drawing of the FLange PM me an email address.

    Maybe if you pm xenonz31 he'll toss the file up on his site? that would be helpful for everyone.

    I use SoldWorks all day long an am interested in trying a few hypothetical’s, it would be easier not starting from scratch..
    Then all we need to do is model in the rest of the car.. LOL…
    I bet this is how similar to how the conversation went when they designed the Z31. Here's my interpretation.

    "hey, this engine rocks… shall we put it in a sports car?"

    ---"uhhh… sure.. lets take out this I6 and put it in this car…"

    "hmmm. OK!"

    ---"now how do we remove stuff if it goes bad?"

    "hmmmm…" *sigh"

    Re: Tubular Headers to keep turbo in stock location

    Well I have done this drawing of how i would like my Manifold to be.

    But after a PM and some measurements from SATAN I'm not sure this will fit.

    So perhaps back to AutoCAD and come up with something similar but more compact.

    Still better to draw it 10 times than to actually build it wrong.

    Re: Tubular Headers to keep turbo in stock location

    It has been quite some while since i have looked at this. With measurements from heads and block in the car I have come up with this design to fit a lot better and also clear the brake master cylinder.

    I am starting to build these in the next few days over my long weekend & i will try and update progress as to how they fit.

    Please excuse my terrible render.

    Re: Tubular Headers to keep turbo in stock location

    I got started on the Passenger side today ( RHD passenger side )

    this is just mocking up at the moment, the pipes still need to be expanded to create the slip joints where each section joins up, this will give me double the thickness for when its welded.

    I will hopefully mock up the driver side tomorrow and see how clearance to the brake master cylinder is.

    Cheers Guys

    I have been to pick up the collectors, & have borrowed a pipe expander tool

    Later on I will have some pics up of the driver side going past the brake master cylinder.

    Re: Tubular Headers to keep turbo in stock location

    I would be interested in stock placement tubular turbo manifolds.

    I am unreasonably against relocating my turbo for unknown ignorant reasons.

    Vagabond

    these ARE going to be stock placement manifolds.....i still need to buy a T3 Flange & do a design for the piping and bracing ect.


    Once i am finished CAD plans will be available to whoever wants to have these built.

    Anyway so since yesterday i have Revised every single pipe to make it fit much nicer and done all the tack welding and added the collector.

    From here this side is done and can go out for tig welding once I build the other side.

    Re: Tubular Headers to keep turbo in stock location

    Is that the right side tubular manifold installed on the left side head? Where is the turbo supposed to go?
