injector size

[bmw2101]

I have a b230 with the E type inlet, it has a 300 deg t5 cam in it, upped the compression, im hoping for 160-190 bhp out of it. I had the volvo t5 injectors in it, but they are damaged. They are expensive here now , what CC of injector should i be looking at. M3 ones are 263CC but im not sure if they are big enough as i the T5 ones were 345CC

thanks

What kind of efi system are you running

I would go for something in the 400cc range giving a bit extra headroom.

Also depends on if you are planning to buy new or source it from the junk yard
