help with injector selection

[bigtalloger]

ok im doing the obd1 h22 in to my '81 crx and im getting down to the small stuff, im planning on going with 12lbs-16lbs of boost, everything is getting worked over by a shop here outside of salem, and im down to the injectors, now ive been thinking of going with at least 650s but the site that im going through dosent have much info on them only size and ohms and im needing some help, can some one recomend what i need. heres the site Performance Fuel Injectors - Marren Fuel Injection, oh and im planing on running hondata ecu so tuning shouldnt be a problem

81 crx???????

psi means nothing.

what power figure are you shooting for?

 

[bigtalloger]

excuse me its '91 crx not a '81, but im using the stock obd1 h22 engine harness, sorry for that

 

[bigtalloger]

im hoping for somewhere around 300-325hp

 

[Briansol]

650's should be more than enough for 325.

you have peak/hold injectors stock in the motor.

it depends on what computer you are using as your hondata base for which injectors to go with, and or if you are running a resistor box or not.

basically,

peak/hold = needs resistor box
saturated = doesn't need it.

the car engine is likely pre-wired for it. look for it. looks kinda like a heat sink, 2x3x.5 inches coming off the fuel rail wiring.

 

[bigtalloger]

are peak/hold injectors high or low Impedance?

 

[Briansol]

low
