So you're saying that I can get one from a later engine and it would be pre-set at the higher 3.0 level? If I'm understanding you correctly (and I may not be) that would be a breeze, not to mention cheap.[/b]
Almost there . Any injected non turbo Saab (900 or 9000) should have a 3.0 bar FPR stock. So it's not a matter of vintage, but whether the engine is turbo or not. So you can find one for cheap in any junkyard, if you have saab ones in your zone.
Sorry if I wasn't clear in the first time.
Wouldn't it run rich, Stefano? Will the '87 LH injection be able to adjust the mixture to cope with the different pressure like Trionic does? [/b]
Yes, it would, but only at full throttle, where before it was a bit lean. O2 sensor would help LH injection to keep things on the right side. If your car wasn't catalyzed, so no O2 sensor like mine, (but I don't believe so because you're in US), yes it would run a bit rich but it just should affect mileage. Stock injections are always a bit on the lean side, and it's always better being rich than lean. In every sense... .
I did not do it in my car because I run on LPG, but I read lot of people on TSN doing it. Anyway, I could be totally wrong, because it's not experience of mine...
