My car has over 140k by now and it takes down quite a bit of oil if you don't like to stay under 4k rpms. So i was thinking of just getting a new(er) ls engine since there fairly cheap, Or since i have a gsr head only missing the dizzy and valve cover.

I was thinking about trying to piece together the gsr engine, other then a full block, ecu, and maybe a gsr harness, How much more would I have to get that I couldn't use from what I have already in my engine bay?
