Compression test values
What are typical compression test values for an early turbo? Just checked mine (after a total rebuild) and they are all steady at 90psi.

Hello, those values sound not too far from reasonable. You have probably a 3 litre turbo in which case you have 6.5:1 compression ratio. When I purchased my car, the compression ratio which was done by a factory dealer showed values of about 110 lbs across the board. A normal 3 litre (SC) engine with 8.5:1 usually has about 140 lbs. Our engines with the lower static compression values will naturally be closer to the 100 lbs mark.
