Personally, no. It's not worth it if you have the option to use the mixer type auto-LPG kit. The only time I suggest the SGI kit is if the intake manifold is made of plastic.

With open/closed loop kits, you can start the car on petrol and once it's warmed up, manually switch over to LPG/automatic function.

In my case, I just start the engine on petrol and switch over to LPG right after I get it started. It's not really a hassle for me, it's almost a habit for me by now.
