For those who have installed aftermarket EFI systems, what size injectors would you recommend for what is basically a stock 2.0L four-banger?

-slightly- higher compression than stock, with headers and I/R throttles.

The basic calculations I did say that 17# is enough, so I figure some nice Ford 19# injectors would be just fine. Am I off base here?

Thanks

That chart is misleading, it shows BSFC at 0.55 which is outside what a normally aspirated engine lives at.. also a rule of thumb is to generally never exceed 80-85% duty cycle.


19# is fine.. Marren has blueprinted 19# injectors for $140/4
