i went to engine depot yesterday with a buddy of mine because hes planning to buy a 1jzgte. we did a compression test and it was reading 260. has anyone ever hit 260 psi on a wet compression test?? i dont know if the gauge is broken but it red 260 across the board. it may not have been in PSI because i was on the phone and i wasnt paying attention while they were testing it. if not what pressure reading would it be?
