19lb Single Pintle Injectors

[jules325i]

I have a 2.9 Stroker and I'm looking for injectors I'm thinking i should stick to the single pintle.
Is there a bmw that came out with a 19lb single pintle injectors or where can i get them.

[sayed ali]

why single pintle?

Why 19lb injectors? If this is a "budget stroker" the stock injectors would be fine. And they would probably be okay for a real stroker. At most you might see a benefit from 17lb injectors.

2.9l 10.5:1, 272 schrick cam, port polish and other head work , oversized valves. hardly budget.

Are m30 injectors to big. i will be running megasquirt.

[sayed ali]

M30 injectors are fine but they are not single pintle

[jules325i]

Ok I'm over the single pintle idea.
so a set of m50 17lb injectors would work.
How many Bar is the stock 325i FPR, And what resistance am i looking for?

[e30leigh]

Do you know the resistance of stock 325i injectors.

[jules325i]

Do you think i will see any performance increase from stock 14lb to 19lb injectors.

[digger]

Be prepared for some rough idle at low rpm if you are using 19# with stock chip.
