    Hi guys,

    Would i be right in thinking that i would get a power increase if i put injectors from a 318ti into mine? or maybe even from a 320/325 if they fitted? obviously i would need a Remap and better induction to account for the extra fuel being injected, but i was just wondering if it is possible as it seems like a cheap way to gain extra power easily..

    any help would be much appreciated,

    Thanks,

    Drew

    im sure there the same injectors drew from any of the n42 engine 316 or 318 i will check for you not sure about the 320 or 325. even if they did with a remap they wouldn't make much of a difference anyway the n42 engine range doesnt really respond very well to tuning there just best left alone. i changed the injectors in my 318i touring for 1's that hand been cleaned and they did make a small diffence to mpg and it felt a little sharper i changed them just for maintenance really because my car is coming upto 100k

    There's a good chance the injectors will be the same, and getting more fuel in isn't often needed unless there is big differences in power, like +25% or more as the injectors usually have lots of room for more fuel if needed.

    Thanks for the info guys, I knew the n42 was a relatively weak engine tuning wise but 115 horsepower seems down right limp wristed for a 1.8 16v haha guess it will just be a remap and air filter then.. Got much bigger plans afoot before that though

    Cheers,
    Drew

    different Injector won't help but a remap probably will, power is not determined by the amount of fuel you shove in (unlike diesels) it is about getting the right air fuel mix and so for extra fuel you need extra air hence why a turbo or super charged engine is more powerful
