Injectors & Fuel rail back on....air bubble(s)? and what to do....?


Recommended Posts

Hey all,

I am about to put the fuel rail and injectors back on/in to my RB20DET after replacing the injector plugs.....now I emptied the fuel rail so I wouldn't get petrol everywhere (obviously :D) when doing the rewiring and etc....but realised when I put it all back in the head...there is going to be a big air bubble.....what should I do about it? is it ok to leave and let it "drain" into the chamber and out the exhaust? or do I need to bleed/prime the fuel and fill up the fuel rail?

Thank for your help guys, much appreciated!

Corey;

just turn the ignition on and get pressure into the line because you'll want to check for leaks before firing the engine. the air will purge and while it might take a second while air gets out of the injectors and the line in total it should be almost instantaneous. don't forget you're dealing with quite a bit of pressure here.

    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
    • There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.
    • yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
