Thanks for conforming this!
Very annoying as I had the correct turbo for this bike, but because this guy insisted on another one I had to remove the old flange form the manifold and weld on a new one, rotate the turbo's bits, knock up a new actuator rod to suit...grrr......
So I will use the part with the flange as the oildrain and the one opposite as feed, the rest wil be unused as there's no watercooling on this bike...
About the dowelpin: yes I could remove it but then there's nothing to stop the compressorhousing from rotating on the bearingcore? I can't imagine that the circlip clamps it down sufficiently?
