Matt 6 Posted July 25, 2007 Share Posted July 25, 2007 I have a slight problem with a 1994 J-Spec TT Supra. When you are driving along it comes on boost with the first turbo fine. As it reaches full boost on the first turbo it suddenly looses all boost and the second turbo doesn't come in. Where should I start looking, any idea's??

SupraJames Posted July 25, 2007 Share Posted July 25, 2007 I had the same prob a while back, turned out to be a tube come off or loose on the vacuum tank. Might not be the same prob as yours, but worth checking all vacuum tubes and intercooler piping for leaks/cracked old tubes. Quote Link to comment Share on other sites More sharing options...
Steve Posted July 25, 2007 Share Posted July 25, 2007 Have a look here http://www.mkivsupra.net/vbb/showthread.php?t=27904 Will help locate the problem, although the pictures dont seem to work, unless my PC is playing up. Quote Link to comment Share on other sites More sharing options...
