Just photoshopped (paint


I've got one installed on my s13, for the price they're a good buy, but I found to get proper control over boost I had to remove ball and spring inside. That caused it to go unstable as, anywhere from stock to almost freeboosting.
Removed ball/spring and bingo. Good as. However then I couldn't raise boost enough, so I brazed fitting up, and drilled 2mm hole through to restrict air flow through. That means that the bleed is in effect, a bigger bleed so I can get desired boost. Probably would be better to weld a piece of steel tubing or similar and place just before fitting as controller isn't made from great material so hard to weld easily. Must get around to getting boost sorted on my wagon. still running stock boost

See how ya go
