fuel injectors

[johnd]

i saw in a post that they used 02 wrx 440cc injectors for there build would they work on the 4g63t head swap

yes, and you dont need the resistor pack.

what do you mean i dont need the resistor pack

[mko]

the DSM injectors that we usually use are low impedance /2ohm/, and Galant's injectors are high impedance /12-14ohm/. in order to run low impedance injectors with ecu that is made to run high impedance injectors you need to get a resistor pack that is connected in the power injector wire to balance the load for the ecu.

the subaru 440cc injectors are already high impedance, so they are plug and play with no modification required

[peanotation]

really? this is awesome news....even the injector plugs go right on?

i know this works on the 8G but i dont know about a 7g as our clips are different

[kamenfaiz]

it will cause shitty mpg?

[mko]

well youre gonna be running rich unless you use some device to change the a/f ratio-maft, safc

Hey Chris will it work without the 4g63 head swap??? will they plug to our heads..? just curious

[bmore303]

Why would you need a head if it connects into your fuel rail?
Anywho, the answer is No.

The only difference in this area is the 64 sohc fires fuel into the intake manifold, while the 63 dohc goes directly into the head.

[kamenfaiz]

and those injectors are cheap!

can any one back that up or will it work on the 7g with the 63 head swap

The WRX injectors use Nippon-Denso (round) connectors, while DSM's, EVO's etc. use the EV6 (square). Now I don't know about the 7g, but I'd think they use the EV6 as well just like any mitsu from those years. All you need to do is go out to your car and check. If it's different, it's easy to wire up new connectors. What I would be more concerned with is the height of those injectors, as the newer ones (8g, WRX) are more compact than those older bosch style's (3kgt, DSM, EVO etc).

if u switch ecu's with say an evo do u then have to run low impedance injectors

[kamenfaiz]

well youre gonna be running rich unless you use some device to change the a/f ratio-maft, safc

what are the options?

[mko]

Options are :any generation MAFT , or any generation SAFC

[kamenfaiz]

is it a stock part or is it aftermarket parts?

You can also use RX7 injectors, they are high impedance and should be a direct bolt on, just make sure you get the ones with the right plugs. Some have bosh square plugs and some have the rounded square plug.

no
