Hello everyone! I’m reaching out in hopes of finding someone that has upgraded their direct injectors on their B46/B48 with either the OEM S58 injectors or any of the upgraded options from Dorch or Spool.

I developed a misfire about a month ago, finally got time to dive into it and turns out the injector seal wore out on cylinder 3. I rather replace all of them for ease of mind. But I wanted to take this opportunity to upgrade to something with more capacity.

I am currently stage 2 or 2.5 F.B.O, (not really too sure about the stages) but I have full race downpipe, charge pipe, exhaust, upgraded ignition coils, intake, O.C.C., XHP custom trans tune, Jordantuned ecu custom 93. I am currently limited on fuel, I could run full e85 to gain more power but I want to keep my fueling at 93 for now, hoping to squeeze more power with upgraded injectors, upgraded cooling. I am definitely going to upgrade the turbo at some point, just haven’t found anything in the market worthwhile.

If any one has upgraded their D.I. please chime in, trying to figure out how the tuning worked out and whether or not it changes the idle characteristics, driveability, etc.

Thanks!

Are you using an upgraded turbo? If not, there's no reason why you should need upgraded injectors, since the OEM fuel system is more than adequate for stock turbo and downpipe on 93; it's even able to handle an ethanol blend (like E30 or so)
