Hello dear forum, I am looking for the perfect car for an LPG upgrade. I would like to have a 335i as a suction tube injector in the A5 Coupe. Explanation: 335i – Great engine with engine capacity with charge, but in the BMW there is no spare wheel dump A5 – Great interior, with about 1.5t curb weight still sporty and spare wheel dump available for Gastank engine: Direct injection do not go, unfortunately, because you do not run well Which car I have caught in the car at the moment is the C 350 from Merced 3.5l displacement with 272hp and 350NM and channel pipe injection, not too heavy body, spare wheel dump available, but missing charging Does anyone have a tip for the perfect LPG engine?
