900i with LPG - is it possible? how?

Question

Hi everybodyIn a few days I'll get a Saab 900i '87, I hope. Considering petrol price nowadays, I'll need an LPG installation.but...Some people from workshops I've called said they won't do LPG in a car with a mechanical injection. I know it's possible, but it needs to have some protection installed in a case of small gas explosions when it sometimes moves back from the cylinders, to prevent destruction of the element which doses gas (I'm not sure of it's english name - throttle?). So, from what I've heard, mounting safety valves on a saab commutator is difficult because of it's round shape (strict tightness is needed). Also, some manufactured safety devices doesn't fit into saab pipes because of their small diameter.I would be really, really grateful for any sugestions on how to resolve it. Maybe there's a good, clean solution, and those guys just didn't think of it (saab isn't to popular here).thanks a lot

Come to NL, or B or I where LPG was/is used, also in Saab turbos. Advanced,3rd generation  LPG systems no longer have an evaporator but use computercontrolled liquid LPG injection.See MH

I know, thanks, it's used widely also in Poland, but it would cost twice the car's price while I'm considering lpg because of economical reasons (still studying). so I have no other choice than 2nd generation solution (btw. I have 900i without turbo).

so my question remains - how to install 2nd generation lpg in saab 900i engine (no turbo), namely - how to prevent gas explosions destroying air flow system? Gas injection in liquid phase is quite a new solution, so maybe there are people with older LPG installations in 900i?

thanks a lot amiran

Hi Amiran,I live in Holland.I drive a 1989 Saab 900i on LPG.Funny: I was thinking of getting the LPG system out,  because I dont driveenough to justify the extra tax they charge for a car with LPG over here. Ormaybe even sell the car altogether.(Lucky me I still have Sven the good old 1980 99 ... :-)What exactly do you want to know? I can simply open the hood (bonnet) andhave a look for you.REgards,Richard.

hello!I would like to know where were security valves installed (between air filter and the engine, I guess). If you have a digital camera maybe you could send me some photos of this wicked thing? It could be easier than trying to describe it, and I could show them to mechanic which would install lpg.thanks a lot!amiran @ tlen dot pl
