Compression Numbers

[cal_look_zero]

Just looking for a "standard" with which to measure my compression on my new to me Legacy.

It put down 120psi cold/dry at 2k rpms this morning; all 4 cylinders. I'd guess this is low-ish and possibly a sign of needing HGs and rings like the PO thought, but would like some outside input.

EDIT: My bad, 91 Legacy, 240k miles, naturally aspirated.

[Legacy777]

For completeness sake and future reference (I thought I posted these before) here's both the non-turbo & turbo compression testing values.

These pressures are at (200 – 300 rpm and fully open throttle)

Non-Turbo (ej22)
Standard – (156 – 185 psi)
Limit – 128 psi
Difference between cylinders – 28 psi

Turbo (ej22t)
Standard – (142 – 171 psi)
Limit – 114 psi
Difference between cylinders – 28 psi
