I said 70k left as anything after 220k I'd take as a bonus, I know they do go higher although I wouldnt like to have to rely on any car above 200k as a daily driver.
At the minute my biggest restriction is time and space, car is currently parked up on my parents driveway and my only real opportunity to do anything on it is evenings where I'd have about an hours light. Now I've got a car for now I'm gonna try and get the turbo off when we start getting longer evenings and try and work out the issue, although I am quite tempted to try getting a second hand turbo, cleaning it up a bit myself and just doing a swap to see if that could fix it.
