    Ebay mate, I got a demon motorsport one for 60£ from memory it was a .7 bar spring but I'm going to run 1 bar using the boost controller, think the general rule is(dont quote me lool)you can run twice the spring pressure with a boost controller

    i run the exact same genuine unit...i think this is a product that you don't want no fake item, too much at risk if it does wrong
    you can get the genuine unit from ebay as well...the fake ones are usually way cheaper

    look to id-workz or TB-developements for genuine tial waste gates mate. as someone just mentioned...best to go with genuine waste gate because waste gate failure could lead to engine damage.

    You will get varios springs with the kit. Make sure you insert the correct one.
