I have here a R31 GTSX which has had a RB25DET put into it out of a 97 front cut, so the problem is it's only running 4 to 5 psi when boost gauge was put on, i also know the 2 stage boost is not there either, so i went and got a bleed valve type boost contoller and it tells me to put it on the hose that comes from the actuator to the front of the turbo, Well the hose coming from the actuator goes to the plenum, i put the bleed valve there and it did nothing, i had a good look and i can't find any hose coming from the front of the housing at all?!!
Can someone please help me with this as 4-5 psi is no good, Might as well had the old RB20 in it still!!
Thanks in advance!!
