Ts sri turbo engine issues

Hi guys I'm lost and don't know what to do yet, I bought a sri turbo not running because of blown turbo, seller supplied turbo and I fitted it and got the car running, however on high revs car blows grey and blue smoke, not sure if its blown turbo seal or rings, I did a compression test and came up with 120psi on all four cylinders, this seems a bit low to me, can anyone help please

Did you clean out intake pipes from any oil in them?

After I posted this I ended up taking lower intercooler like off and a litre of oil came out lol

keep us posted on how it goes

Bottom end bearing on cylinder one ended up letting go, time for a new engine lol
