gavin.starr Posted August 3, 2009 Share Posted August 3, 2009 after loosing boost on my second turbo i decided to buy a new to me set from michel lane on friday. (there was no ceramic left on the turbo at all when i inspected it, hence th loss of boost in tubby 2) i have grafted my arse off this weekend to get them on, now that they are on i have no boost coming in from the first turbo:banghead:, am i now right in thinking that my vsv's may have gone as well or would that not be the case. what do i need to be taking a look at to solve the mistery. gav Quote Link to comment Share on other sites More sharing options...

gavin.starr Posted August 4, 2009 Author Share Posted August 4, 2009 oh and another point i wanted to add is that i get no boost from either number 1 or 2 in first gear, say i set off from a set of lights it travels all the way through first gear with nothing, once i get into second gear there is nothing from turbo 1 and then a kick comes about 4500 rpm from the second and so on through the rest of the gears Quote Link to comment Share on other sites More sharing options...
gavin.starr Posted August 4, 2009 Author Share Posted August 4, 2009 here you go: http://www.max-boost.co.uk/max-boost/supra/turbo.htm just checked them all an found one to be faulty / caput so hopefully this is th cause of the problem. does any one on here have a working second hand set or know some where that i can buy new. are these valves cheap or expensive if there not oo bad a might replace the lot. cheers fella gav Quote Link to comment Share on other sites More sharing options...
