the isuzu lump runs 7psi standard (just under 0.5 bar) there is a small black pipe that goes from the turbo to the actuator . get under neath the car and check for splits or if its even there . if the pipe isnt there it will run full boost and you will hear the safety valve popping all the time .. you could leave it but i suggest turning the pump up if you do (see 1.5td tuning guide on here)

yer goes in mate.. i didnt give a fcuk about my engine as i won the car cheap on ebay and droped it into a non runner corsa which i also got very cheap.. i welded the safty valve up haha and a bolt up the actuator pipe, cleaned up all the turbo etc, ran a filter pritty much straight from the turbo and welded up a bigger bore exhaust.. was a little wepon for £300 total
