Compression Test

alright, heres the deal, i have 1 88 gxl that i know is screwed, but i bought a 87 base model with lots of extra parts, s5 taillights, mirrors, the 13b in it with 5 speed, and an EXTRA 13b with a 5speed, extra hood, extra hatch, 4 doors, polished EXTRA set of wheels (not the ones on the car), for $600 from some guy last night....now i have the engine in the 87 and a longblock out of the car...is there anyway to do a compression test to get the actual numbers on the one in the car & the one out of the car, or do i have to take it to a mazda dealership?.....and if so, how much does a simple compression test cost?

i believe its the leakdown test that can be done outside the car. or you could hook up a tranny and starter outside the car and crank it.
*no idea on price*

BTW, it does yet sound like a pretty good deal if you put all of that together into a car or something.

A big block Chevy strapped into little more than 2000 lbs........that would be a Stang killer easily.

get a remote starter and a battery and you can crank the engine over for a compression test.

it's pretty damn hard to test an engine out of a car unless you have a test rig built up. And that still doesn't tell you about coolant/oil seal problems.

About the best thing you can do is crank it and listen for chugs. Six even chugs = good motor

If any of the chugs are weaker than the rest, the motor is crap.
