Andy,

 

You know when you and Az were messing about with his car? Then two same sided turbo's turned up all the way from down under, how the f\/ck did you manage to fit them?

 

Not having a pop mate, serious, I've got that second hand set for mine and I'm trying to comprehend how you managed it!

Easy peasy m8! The exhaust and compressor housings can be rotated around the centre cartridge ;) Usually some bolts with washers that clamp the housings in place. Just get the housings so they point the right way when the oil feed is at the top. The only other thing you'll need to do is reposition the actuator for the wastegate - this required drilling and tapping new holes in the compressor housing but wasn't tooo bad ;)
