Hi,
New to the forum, so please help, i have a 1996 d14 civic and in the process of gathering turbo parts for my build in early may.
the main thing i am concerned about is the fueling.
Does anyone know what size the standard injectors are for my D14A4 engine and recommend what size injectors and also fuel pump to use........
Thanks

Hello & welcome mate, theres no standard to the Injectors I'm afraid, what power you going for, do you want to use high or low impedence... some people use 310's, 440's 550's, I've got 650's I know someone running 1000's, have a look at this link:-

You wont need that much to achieve that tbh, its only about 40-50 bhp over standard.

so EDD would you say to keep the standard injectors and fuel pump then and get a tune
No no, you might be ok using standard fuel pump but run Prelude H22 injectors at least, and yes it will need mapping.

Example, I got Crome now, three tuners had not heard of it and only one of them was willing to have a go, a fourth one said I should pull it out and use Hondata as it was easier for him to tune, the fifth said its crap and full of ignition bugs and I was going to blow up and was doomed.... the last one said Its was alright he supposed, but not his first choice and he has not rung back :confused:

Unless you're going 300bhp plus, the stock fuel pump will be fine.
And as for mapping, run a P28 ecu, socket it and run Neptune or Crome Pro. The boggo Crome is shit.

^^as above, run a P28 chipped ECU, a 255 fuel pump, however im not sure if you will need a resistor pack to run bigger injectors as i had to do so for my B18c4, to run 510cc injectors.
