I have a Tial V44 44mm external wastegate for sale, in silver. It's used but with low miles, comes with original box, v band clamp, two flanges and a pack of those tiny screws. It only has 1 spring in it and I've not yet opened it up to see what rating it is. It's had a new diaphragm fitted (have copy of receipt for this), I bought this off passionford from a guy who got it direct from Harvey Gibbs / SCS. I have the serial number so will post that later. Only selling as I am going twins. £170 posted ono.
