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 -Josh2 |

I am using the 1.7L injectors on a stock 2.0L with SDS fuel injection and
even they are a bit over kill. If I recall they are 265cc injectors which should be good for about 175 HP at 100% duty cycle. Ideally I think you want to run around 80% duty cycle. You could probably run something around 200cc to 225cc without any problems. keep in mind these numbers are based on 100 HP 4 cyl engine. |
