So some have seen my itb m30 build, I’m getting into the gritty jobs now & looking at tackling fueling next week. So far the motor is a factory b35 bottom end, with a ported head, oversized valves, catcam 294/294, & a RHDengineering itb kit. Let’s talk injectors/fuelling required to keep it happy. Originally the car was a poverty spec 318i even worse an m40 when I swapped the m30 in we keep the factory fuel pump which was the same part used on 735/535’s apparently.
Does anyone know the flow rate of the 318i pump I believe it’s around 195L/h?
Injections- looking at 370cc Bosch for tuning windows to be smaller, or is the jump to 440cc a negligible difference? The 440 aka 42lb are more widely available
I’m planning at overbuilding the fuel side for future updates & move to e85 down the track & the new bottom end needing more fuel, In have an AEM adjustable reg, -6an lines moving & regulating pressure which is definitely overkill
