i am ready to purchase the following items:

aem fuel rail.
aem fuel pressure regulator.
walbro 255 hp fuel pump.
new fuel filter.
rc injectors.

my setup is a obd0 dohc zc on an 89 crx si.
ive been saving up for this, took me a couple of months but i have enough.


now on to my question, since ive never dealt with a fuel system before.

1. will a d16a6 [crx si stock motor] aem fuel rail and pressure regulator fit my dohc zc? or should i get the one for the d16a1 [89 integra motor]?
2. whats the preferred fuel injector size? 1000cc, 750cc, or 500cc? will i have to convert to obd1?


thank you.

 

ummmmm are you buying all this fuel system stuf cause your boosting it? If not factory injectors will do just fine. at most GSR/LS injectors would be more then enough

 

hmm well im not boosting soon, i just figured since im getting all brand new stuff for the fuel system i might as well get injectors.

would you suggest just getting obd0 gsr/ls ones? or getting them serviced [cleaned]?

 

plus i just finished upgrading my suspension and braking system. so i moved on to the motor.


its a slow build.

 

thats what'd do... the others might be a little bit over kill

 

alright. recap.

parts list:

fuel rail
regulator
fuel pump
fuel filter
gsr injectors

so no rc injetors what so ever.

but will a d16a6 fuel rail fit on a dohc zc?

 

oil the threads on the fuel rail, if not they will leak because it won't be torqued well if not
