    how do you mean 'set these up' ?

    they have springs in, to vary the pressure they'l open, like internal ones.

    Its a little bit of an open question but generally speaking on the Tial gates I have used (I have an MVS myself) you need to make sure the spring rates are set right to get the right crack pressure... this can vary depending on your setup/manifold/turbo etc... I have fitted Tials that are 'siad' to be set at 1bar but have made more boost when run on the dyno so needed adjusting..

    The actuator is integral to the external wastegate.

    Just to clarify... you can't just bolt on an external wastgate to a std K04/whatever setup... external gates are for turbos that don't have a wastegate and actuator built in (such as the K03/K04 and some larger turbos like the GT28rs and GT2871r)...

    For example on my turbo I used to have an internally gated hotside so had an actuator (like the K04)..
    K04 internal wastgate..


    My previous GT3071 with an internally gated hotside..


    ...and now as externally gated with a Tial wastegate...

    i did know that one lol that you cant bolt an external wastegate onto a standard ko4, was just curios about an actuator and if u need to do anything to set an external wastegate up.

    Got the car coming off the road shortly to be rebuilt as soon as i can find some 1000cc injectors

    What spec are you going to rebuild it to as 1000 cc injectors then you will need a massive turbo to match

    I think your 3" MAF might be a little undersized!
