I'm thinking bout buying a Supra Twin Turbo and i know i should get a compression test done. What would the compression test numbers be around that are good?

Make sure car is warmed up to the operating temp before checking compression. 160 PSI plus minus 5 PSI is what you're looking for.....but even more so the balance of compression across the board. Make sure there is no difference greater than 14 PSI between highest and lowest reading. Remove EFI1 and EFI2 fuses, all plugs, and floor the gas pedal while cranking.
