Injectors/atr inlet

Post by **newkid** » Fri Oct 14, 2016 8:10 pm

OK been thinking about this. Is the injector ports only modified due to obd1 injectors having a different spray pattern? If this is the case surely I can use Obd2 injectors without modifying the ports? I'll need to obviously bypass the resistor box but surely that's an easier option than modifying the inlet and then having custom fuel rail mounts made up.

I don't know if it help but i'm running F20C S2000 injectors on my ATR, and without any modification

I ithink using the a8 injectors you still have to mod the inlet but if your happy to obd2 convert it then why not stick with atr injectors? My mates type s runs them with no mapping and it's perfect

Cheers guys.

@nafemannatgan how did you run s2000 injectors did you modify the resistor box wiring?

Well it's an ATR lump in a 5th gen, so no modifications required. Just needed to change the map to suit.

Know how to bypass the resistor box?

Yep, the 4 red wires and single black (or vice versa) that run into the resistor box need to be cut before the resistor box and all 5 spliced together.

I cut the plug off the resistor box on mine, leaving equal length tails and then splices those together. That means you're not hacking up your main harness.

I did a write up in my build thread if you can find it

Yup found it. Think I'll go down the route of atr/s2000 injectors then.
