injector upgrades

Just wondering if anyone has replaced their injectors and fuel rail from side feed 2 top feed?

I've heard that Mazda 13B s6 injectors and a custom fuel rail can be modified 2 fit the RB25.

Does anyone know any more about injector upgrades?

Does it work out cheaper than aftermarket rb25 injectors etc?

Akira,

I have been looking at getting either Nismo or Sard injectors when i upgrade my turbo and increase the boost.

Sard injectors are dearer although i might grab some while im in Japan next year.

Akira,

Mark at Hills is sourcing me some 680cc injectors (brand new ones) I can't think of the brand or price off the top of my head, but when i go to see him next week re. my new turbo, i will get some details for you.

i need a phat fuel pump too.

Sweet, I have no idea what brand half the stuff on my car is .... although my fuel pump makes a cool "bbrrrrrrrrrrrrbepp" noise on startup :P I'm hoping to use Mark's services for a few things in early July, do you think for a price he'd be able ot show me where half the aftermarket mods on my car are and what type they are etc ?

Jimbo,

Please give me a PM Re: 550cc injectors. R they side feed or top feed?

Prank,

I,m currently upgrading my fuel pump 2 a GTR internal item. Can always add external pump and surge tank later if required, but GTR pump is doing fine on current set up.

What fuel pump do U intend 2 run?

Prank.

I was going to run something like a bosch motorsport unit in my car although my friend uses a HKS Pump which he believes is around 100-200 extra.

Meggala: thanks for the info about the 33's i always thought that anything over 200kw was requiring some fuel system upgrades.

I plan to do my injectors and pump when i fit my turbo...

Decisions decisions

    • Thanks for the reply, So i've continued playing around, and fitted the injector adaptors onto the injector, the fuel rail is not able to be mounted now as the injectors sit a bit further out. I suppose the point of the adaptors is so that the injector nozzle isn't so deep into the intake? I suppose 1mm extra on the o-ring would do it but still can't mount the rail onto the intake haha. Waiting on a reply from Aeroflow I'm sure there's something stupid that I'm missing...
    • I have a radium fuel rail on my Greddy manifold and used the supplied radium fuel injector to manifold adapters (The round green things pictured). I did always wonder if you could just go ahead and use the second lower hole like you're doing... Wouldn't thicker o-rings solve your issue?    
    • From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"
    • Hi all,  I have a older model of the Greddy Front facing intake on an RB25DET NEO Head. I've bought aeroflows fuel rail and injector kit (1000cc Bosche injectors) and I'm unsure if the fitment is correct. The injector o-rings fit in the intake hole but it's not snug. I can very easily rotate the injectors even when the fuel rail is mounted. The kit also came with multiple adaptors, they dont make it any more snug and using them raises the injectors up and i cant mount the fuel rail. I hope this makes sense I've asses a few photos.    Thanks so much guys.
