i did the compression test & watched the needle bounce on the guage, it took a few attempts to get the 3 seperate readings for each rotor & they are by no means 100% accurate but definatly with 0.1 bar of being accurate.
The cars done 82000kms so about 51000miles. i change the oil very regularly (2000 miles) for castrol gtx mineral oil & change the filter on every other oil change. As soon is it arrived in the uk it was checked over by DS Engineering who are a local rx7 specialist, i was told it was in very good & clean condition & all that was needed was new spark plugs, air filter & some new vacuum pipes, it has a very very minor oil leak where the pipe goes into the oil cooler but not big enough to be noticable.
Its working perfectly & needs nothing doing to it.
