having finally got the 90bhp intercooled engine running in my van, i have fitted a boost guage to it, T' ing off the pipe that runs off the turbo to the actuator. i have wound the actuator arm in quite alot, turbo is whistling well but im only reading 5 psi at 3k. changing the T piece to the pipe that goes to the diesel pump gives the same reading.

i have also changed the turbo for another and used a different guage but the reading is the same.

Does anybody have any tips on where i should check for leaks or has my turbo and/or actuator had it? id like to fit a fmi to it and turn the pump and turbo up a bit, not huge amount though.

Any help would be great as its going nowhere at the minute!
