I'm swapping 13B-REW into 1985 GSL-SE. Before I decide what ECU to install, I'd like to get the engine running, without a turbo on N304 ECU, stock ignition.

Is it possible to run high impedance injectors with N304 ECU?

Do GSL-SE's have injector resistor pack, just like early S4's, that can be bypassed?

I'm trying to run FD's 850 secondary injectors in the primary rail. Option 1

Any tricks on installing stock GSL-SE injectors into the S6 REW center iron? Option 2

Im assuming, since S3 and S4 TPS is identical, i can run S4 TB custom mounted on S6 UIM.

T2 TB cover with IAT. S3 AFM.

Does removing an IAC affects idle dramatically on N304?


any other possible issues or recommendations?

 

since the high impedance injectors take less current to run (ohms law), then in theory you can run them.

850 secondaries don't work very well as primaries, they don't physically fit the rail properly.

i'm sure its a matter of O rings, once you figure that out, this is the better option

too much work. just use the narrow range of the FD TPS..

yes, but it'll be so far off everywhere else that you'd probably never notice

 

Would I have to custom mount the IAT?

I assume, I would have to cut the FD TB elbow to clear the stock fan shroud.. any pics floating around?

I'm also looking for a cheap alternative fuel pump. I gave my fuel pump away to a friend who needed for his daily driver.

Is there a fuel pump from another common car available at wrecking yards that could be used instead of the stock one?
