    Yeah here's some updates for you...

    I got a bunch of goodies in the mail including a flange for the head:



    After realising the flange for the head is for a different size pipe, I decided to remake my collector (wasnt the happiest with the original one). I've also improved my welding quite a bit since then.
    So I bought a new saw, and made a jig to hold the pipe in place.



    Then I cut up my collector pieces and ended up with this:



    Then I welded them together and ended up with this:





    Turned out far neater than the previous attempt. I'm pretty happy with it.
    Now I move on to making the rest of the manifold.

    So after an eventful day of welding / fabrication, we came up with this:











    I've positioned the collector in the right spot with some steel bar temporarily, then tacked up the first runner.
    The next step is to tack up the other runners in place. Then I'll remove the runners individually and weld them up.

    The steel bar will get removed once it's all complete.

    When you going to clean that rocker cover properly dude....? LOL

    Do you fill the inside of the tubeing with Argon when your welding guy...?

    And are you going to make a bracket to holt the collector in place when your finished, or just going to rely on the runners...?

    Yep, I've tested it with bluetack, its probably got about an inch of clearance on the hood.

    I'll clean up the enginebay after finishing fabrication. What's the point of fixing it all only to get it dirty when working on it?
    The valve cover paint actually got burnt by the exhaust when I had the leak at the turbo. I'm going to have to sand it back and re paint it. Not overly happy about the whole situation.

    No need to fill the tube with argon (also known as backpurging) because its mild steel.

    Considering making a brace for the turbo off the block somewhere. I'm in 2 minds about this.

    I was under the impression back purging was still a good idea. Even with mild steel.

    But what I know about welding could be written on the back of a postage stamp.... (don't wear thongs!) lets see who has followed this thread....!

    I am having a bracket between the 2 flanges of the manifold. And a bracket holding the snail to the block... (overkill perhaps...)

    No need to backpurge on mild steel...

    Onto the #2 runner. Here's some images:







    I think I spent about an hour trying to get the last little bend to fit up. It's painful, but I'm really happy with how it's turning out.
