Possible lucky buy for good turbo engine from junkyard. need advice.
#51
Find a used transmission. It can be completely junk. You just need the bellhousing to bolt on to the engine for the starter to have a place to mount to. Someone's gotta have one around you...post in your local forum section. Then all you need is a starter, battery and wire. Then check compression. You'll get a much better idea of the shape the engine is in. Good luck.
I was just gonna take my chances and hope for the best since I cant afford a rebuild.
Does it matter if engine is dry w/out oil in it for the test? (Dumb question I know but I figured I'd ask)
I'll make another post and see if anyone can help me get it compression tested.
Today it was really nice, 70 degrees here in Va , may start working on taking out the engine that's in the car soon, want to see if I can fix its coolant issue.
Even if I do get it to run okay the Turbo has side and end play, and there's a few things I'd like to do for preventive maintenance.

Your video isn't a real compression test, but more of an "apex/side seal test" and it passes. Only other functional test you can do is fill and pressure test the coolant system. Extra sealant, obvious porting, mis-matched series parts, and a mazda reman tag on the front iron are the only external ways I can think of in order to tell if a block has been rebuilt.
Axial play in the turbo is definitely bad news, though. Prepare to replace it.
