hi dave thanks for the info today i have taken the bleed valve off of the car and taken the air filter off to see if there was a air flow problem i went for a drive and the boost goes to 0.2 bar with no bleed valve and the pipes conected stright to the turbo and the actuator i looked at the actuator and it is a standard one it looks like it is an old actuator just been painted and you can pull the arm out really easy, so i got the other actuator i have which is a uprated thing that is anodised blue and i can hardly pull it out it is really hard so it maybe a faulghty actator my dad has run turbo technice to see what they say about it. the inlet pipe is quite soft it is pritty old and quiet oily and slimey i supose that isnt helping matters. the timing issues are that i bult this engine with the help of a friend with all the zvh conversion bits but when i put the timing belt on i notice that the belt would not fit on unless one of the pullys was turned either clock wise or anti clockwise so i set both top and bottom pullys TDC adjusted the cam pully so the belt would fit but i have a timing light will look at the timing tommorrow in the day light. how do you set the ignition timing to 12 d BDC does that involve moving the dizzy and with the timing light setting it a 12 im not to sur how to do this and way thanks for the help rob
