Just tested my compression, is this reasonable?
Hey guys, I just did a compression test on my car. The car was running fine as far as I know, no smoke or anything, no burning oil. I wanted to make sure the car is up for turbocharging duties.
results were 199, 199, 187, 173
The only thing that bugs me is the 173 but it's less than 15% off so I think it would be fine. Anyways, the car has almost 120k miles and it's a 91 1.6. Should I be concerned with anything or is this thing ready to go?

Don't be a *****. Turbo the car. What's the worst thing that happens, you get confirmation that the engine needed a rebuild anyway?
