This really need a new top end??
Discussion
Compression results are usually in PSI, not %. I guess % could be the percentage of what the original compression would be, but that would be a very odd way of doing it.
The more useful test would be a leakdown test and this does give a % result. If those are for a leakdown test they are thoroughly decent for a 90k mile engine and most folk wouldn't suggest the losses to be high enough to warrant a rebuild, but the test needs to be combined with other observations and checks to be sure.
As well as a leaky top end there are loads of other things to worry about on Turbos, especially little used ones. You can easily spend thousands on the fuel injection system alone.
If the 3rd gear synchro is iffy a gearbox rebuild is usually 'only' £1000 - £2000.
Get it properly inspected, £20k can go in the blink of an eye if it's ropey.
