    AAN Inlet Manifold on 3b

    Now that ive fitted this big i/c i now need a reversed inlet manifold really, to get rid of quite a lot of pipework. So i decided to have a go at modding an AAN inlet manifold like mark and doug have done.
    Ive been doing it at work, lots of equipment to use i just dont have a decent tool collection to manage it at home.
    Its pretty much done now, so heres a few pics of how i did it. (some haven't come out too well)

    Firstly, chopped the side off with a waterjet machine lol,

      I dont have much room (if any) to move the rad back, so at this point decided to do a bit of 're-engineering' to it. Chopped off part of the front, so i can mount the throttle housing further forward.

      Access tubes removed and holes welded up.

        Rebuilt section, now throttle body wont have to be tilted down so much at the front, so should clear rad. Thats the theory anyway.

        I want a tig welder.

            Thats pretty much it. Got a couple more things to do, bracket for throttle cable to put on etc.

                        Ive beadblasted it, and will get it powdercoated silver.

                        I reckon about 6 hours work to get to this stage.
                        Needed the car for work too, so it was a bit of trial and error getting everything in the right place.
                        Will it fit? fook knows.
                        Will it leak? better not or its getting smashed up.

                              Dunno mate, in the stock AAN position air flow points to cylinders 4+5 as you can see in the second pic, now it points at all cylinders albeit right next to no 1, maybe the proper engineers on the forum could advise.
