  1. Saab 9000 (1984 - 1998)
    Hi all, I have a 1990 9000 Carlsson hatchback, with the two litre turbo motor. B202 (?). The BPC is working as I believe it should, but only 2 of the pipes are connected. The C pipe (top of the BPC) is hanging loose and not connected to anything and there doesn't appear to be any place to...
  2. Classic Saab 9-3/GM900 (1994 - 2002)/Conv ( -2003)
    First time posting here, long time lurker though. Could someone put a voltmeter on a BPC for 2000 9-3 SE and read the OHMs for me? It's one of the 2 pronged ones. I've been trying to hunt down a boost troll for a few months and everything is pointing to BPC. The 2 I have now are showing 7.5 and...

    Based on the stock Boost gauge it looks as if my car is stuck in base boost. I tested this by hooking up the compressor vacuum line directly to the wastegate. This would bypass the BPC and run stock waste gate spring Boost which i believe is 6-7psi. I dont really want to buy a new BPC due to...

    How is this possible? (NG900 T5) - while setting my base boost I unplugged the wires to the BPC valve and imediatley noticed how the car pulled more strongly and smoothly in low revs and low boost and also the anhoying hesitation between 1st and 2nd gear changes was gone). The BPC passes every...
  5. Classic Saab 9-3/GM900 (1994 - 2002)/Conv ( -2003)
    Has anyone ever got anywhere with sourcing an alternative valve - the main problem as far as I can see is simply that the on the T5 fitted unit as per 1997 NG900 this valve has 2 sets of coils (and hence the 3 wired connection) most decent quality aftermarket ites appear to be 2 wired single...
  6. Saab 9000 (1984 - 1998)
    I have a 1995 9000 cs turbo and would like to upgrade the ecu. I know that I need to add the bpc. My question is will a 1994 Aero ecu work in my 95? I know the 1997 ecu will give me a check engine light because it is looking for a second oxygen sensor. I also know that 1991 9000's have a...
  7. Saab 9000 (1984 - 1998)
    Hi All, I have recently acquired a lovely example of a 97 9000 aero (manual). So far It has been a complete pleasure in the month that I have had it, however, now and it has developed a small fault. I have browsed this forum for quite a while but I just can’t find a solution to the problem, so I...

  9. Saab 9000 (1984 - 1998)
    Hello All, Noticed yesterday whilst driving car (2.0lpt cse without intercooler )that the car seemed to be a lot smoother in acceleration and did not quickly drop revs when changing gear. It required a look under the bonnet and I found that the metal clip holding the plug onto the bpc...

    Hello I have a 2000 9-3 LPT (UK spec) On a recent inspection of the engine bay I have found the middle hose on the BPC (I think that's what it is) is not connected to anything. Where should this connect to, and what effect has this had on my engine. Thanks
  12. Saab 9000 (1984 - 1998)
    Anyone know if the BPC valve from a 2001 9-3 will work with a 1991 2.3 turbo? I know it wont fit in the same place as the 91's original one, but are the boosts the same?
