bigger injecters=mod?

[bimmerguy82]

I have a question. If I increase the injector size above stock,( not sure what stock is) i.e. 21#. With a CAI as a mod i already have, will that create enough air/fuel mixture as to not run rich, or would i need to have boost?
let me know if i need to be more specific.

increasing injector size will not do you any good.

Just increasing the injector size will not, but if you get a chip+injectors (programmed for the bigger injectors and other mods that you have) then yes it would help. But injectors on their own, no. Assuming that your CAI actually works and increases the airflow.

pretty sure there is no need to go with bigger injectors on a 325 unless you do some FI. the stockers have plenty of headroom for the power that motor is going to make N/A.

the only way bigger injectors are good as a mod , is when you max out your stock injectors. in the case of NA , or to be more specific bolt on mods, there is absolutely no need to install bigger injectors.

with a n/a 325 your are going to be hard pressed to make much more than 200whp.

Word. My buddies 230 rwhp m52 328 is still usign his factory 21 lb'ers so im sure you're fine. Also, BMW gives lots fo headroom on these injectors to prevent strain on them.
