Injectors and mapping question.

[M20olly]

Hi,

Please can anyone tell me if these injectors are good to use on my M20 2.7. I heard something about bore washing if you use the wrong ones.

Asking as I have a new set. Bosh 060 0280150415 562 ?

Thanks

Also any heads up on a good place for M/S mapping, someone who has good experience of an M20 so as to save trial and error? South of england preferred.

Those are 166cc/min (16lb/hr) injectors. They should be adequate up to about 180hp with a stock fuel pressure regulator.

Thanks, could be on the small side if I'm looking for over 200hp then. Do you know if they are higher flowing than standard M20 B25 injectors?

Standard M20B25 injectors are 147cc/min (14lb/hr). If you are going for over 200hp then you need at least 200cc/min (19lb/hr) injectors. The bosch 0 280 155 700 are a common swap. My 2.8L stroker is running those injectors without any issues and I'm currently making 182whp (roughly 205-210hp at the crank)

Thanks Bullet, I think I have enough to go on now.
