going to be doing a compression test tomorrow due to burning too much oil, i suspect it`s the turbo but want to rule out the engine before i spend on rebuilding the turbo, so question is what are the compression ratios on a V3 Type RA STi? or what sort of figures should i be looking at for a healthy engine?

IIRC, the minimum compression pressure should be 142psi with the engine warmed up and the throttle wide open when cranking for the compression test.
