I have a volvo 340 GL, a 1.7 engine:


Car runs very well, but when I´m turning very fast engine stop sudenly, and at the moment it runs other time. I change the fuel pump and it runs better, but if you go very fast it do the same. Any solution? My first fuel pump has 1 inlet and 2 outlet, and the "new" (2ª hand) has 1 inlet and 1 outlet, but it has a fuel presure regulator (I think) that has 2 outlet, 1 to the fuel thank, the old pump hasn´t got it.
I would like so to have any more hp, any cheap and easy mod? For example I think in a renault carburetor, thar it the same whit different venturis and jets, and renault has 90 hp.
So, I would like a LSD, but I don´t find anything. Is a weldded diff a god solution? Problems whit it? I use the car in asfalt.
Best regards, excuse for my enghlis.
