any help i would be greatful,

its for a 1jz soarer engine BPU , (in a supra)

DAZ.

The only way I can see that the manual one could work is that there is a ball and spring under adjustable tension arrangement, like some manual boost adjusters have, and when a pre-determined level of pressure is met at the ball, the ball lets the excess pressure escape to atmosphere. Now that could be wrong, but I cant see how it would work otherwise. If that is how it works, I wouldnt feel happy about using it, think it would leave too much to chance. That's just my opinion.

i have the manual one fitted to my vvti as the electronic one would not work, so i was told by fitter, no problems and been fitted for couple years now

We've been using them for awhile now and they work a treat.
