does anybody know what the compression should be for an '86 GL10 "turbo"...I know that for my '86 N/A EA82 motor with 200,000mi. on it comes up at about 160-165 across the board

Here's the chart from the '89 service manual.

 

 

I'm not sure of the cranking speed but my EA82T (RX) with 272,000 miles measures 130-135psi.

thanks for the info..I took the compression test yesterday and it also came up to about 130-135 after 5 turns..this motor has had a lot of constant cold starting with about 180,000mi on it...still passes the emission with flying colors....keep up what ever you are doing (driving habits/oil changes etc) you probably have another 100,000mi before having to replace that motor
