    if you can find one ak miller was good for most applications,

    other wise most people make their own or adapt something else to fit

    Manifold made from lazer cut metal (don't try this with stainless steel)

    Query - Why? Whilst MS is easier to form and weld, the number of MS manifolds i've seen that have been fab'd up, used and then cracked - multiple times, its not a good choice. When running under load and the manifold gets red hot, hanging a turbo off the end of it when it's liable to soften without support, isn't sustainable. I would seriously suggest use of 3+mm SS even with the fabrication aggro would produce a good long term solution.

    Cracked mild steel manifold are manifolds made from too thin metal. For a turbo manifold I suggest to use at least 4 mm or thicker.

    My experiences with SS is that it cracks, special when water can reach the manifold. On Ebay, lot of SS manifolds are offered, they all crack when using turbo's. Not enough "flex" in the SS. When we changed from SS to mild steel, the number of "lost" waste gates and turbo's stopped. Please note, in autocross, turbo where running in free air, water could reach all the parts. But the same setup and metal was not a problem.

    Likewise on bikes where most of my experience is - exposure is absolute behind the front tyre! Many variations of single or dual wastegates, either mounted to collector or the turbine housing are used.

    I understand it is the worse place to get rid of water. Maybe they use softer SS but in all my setups, and compared wit the stories and failures on internet, it was not the best option. We had to keep welding and welding.

    As I said, we changed to metal and the problem was solved. Only, it does not look very well after a few years.

    I have never used anything else but normal steel pipes, 2.6 mm thick. Never had a manifold crack (but the long one has a support for the turbo weight).

    For mild builds I usally recommend an adapter to a standard Sierra (twin exit) cast manifold but you won't find that in the US.

    Most easy way to build a turbo manifold from a twin exit Sierra is to cut a turbo exhaust scroll and weld it to the manifold. They weld very well with nickel rods. You do need to skim after welding

    Not the best flowing i've seen but construction looks stout enough!

    Original manifold was grind-out inside before the turbo scroll was welded on. Flows like any log manifold. Made over 200 Bhp with only 600 mbar and a carb. Job wel done if you ask me.

    I was thinking of the later Sierra EFI manifold:

    But that is unavailable in the US anyway ;-)

    Re: Best Pinto Turbo Exhaust Extractor?

    It's indeed a lot better made, almost perfect but it did not fitted my Sherpa Leyland the days I was building this turbo engine. My turbo had to be very close to the engine, no space for a manifold like this one.

    The manifold I was using was the carburetor version with twin exit but internal almost similar as this one. By grinding it all open so 1-4 and 2-3 could come together before going into the last part it was not so bad at all. But this one is indeed a lot better and even a very good option for real high power. All depend what power you are after. And space.

    I guess I'm the only one wondering what an "exhaust extractor" is....when everyone else is showing pictures of exhaust manifolds ?

    The Sierra adaption above looks like a very tidy idea

    I can only imagine it is the word they use for exhaust manifold. Lot of people call me and have complete different words for emulsion tubes, pump jets (like injectors or shooters) etc...

    In USA they also talk about a "motor" where the same motor is "engine" in England.

    The only funny thing is, we are talking to ourself, no replay seen from DrDave. Hope some other Ford Pinto maniacs can use the info. Otherwise, I feel stupid putting my time into it.

    Re: Best Pinto Turbo Exhaust Extractor?

    To me an extractor would suggest further back, not the manifold itself. Certainly I use a lot of US forums, and it's not a term I've heard any of them use for a manifold. Turbo manifolds often get called manifolds, and tubular types get called headers.

    but yep...the OP posted, then pissed off lol

    extractor manifold is a fairly common term down under i think, although i do recall here in the 1970s people often referred to extractor manifolds, meaning tubular 4 branch as opposed to OE iron log manifolds.

    the phrase does actually make some sense, tubular manifold creating scavenge and thus extracting air from the cylinders, although clearly theres such thing going on with a turbo

    I was not trying to explain manifold extractor was a correct word in USA. Sometimes people give them a new name, like 'shooters' for acc. jets !!!! just because they don't know what the real name is.

    Don't feel stupid Onyd, your posts are always intereting to read and your information is correct.

    What's happened to DR Dave his anyones guess, it's so strange because he was asking so many questions I thought he was the Police.
