Well, i just bought some 550cc injectors, and await them to ship to me from the good old states ...

$405USD for fully cleaned, flow tested, and matched to within 3% of each other ...

they are a direct drop in replacement for the rb25 !!!

available upto 650cc !

mmm i got my friend  Sard 550cc injectors for an Rb25 for $600 (New in Box & incl. shipping from Japan)

So yeah, you did well !

Yeh?? Thats bloody cheap, where from. I think from memory somebody on SAU said those injectors 'sard 550s' can be a bit of a bitch to fit onto the RB25.

I have a good friend of mine that lives in Japan, he will send me anything i want. So basically there is no mark up on the cost of whatever i buy.

He constantly says that because he is from abroad (he is australian) he is treated really well and gets fantastic deals from workshops etc.

I dont see how they can be a 'bitch' to fit? My friend had his injectors installed by Amberleys and there was never any fuss... How can they be a bitch to fit? They were Side Feed injectors *shrugs*.

Man i dont know, i read some thread about someone recommending the nismo ones over the Sard ones because they were an easier fit... or was that the sard ones were an easier fit... :) Hahah I'll take ya word for it.

  • 2 weeks later...

ok, the injectors arrived, and luckily i did not get stiffed for GST .. rar !!

anyway, well packaged, each inj has been marked with a number, and that number references the service report that was included, out of the 6 inj they flow :

report also shows in lbs/hr and has a nice little flow correction for psi chart.

553cc, 564cc, 564cc, 564cc, 569cc, 571cc

this is a 96.8% balance

hmm, i wonder which inj will be in #6 :)

they also tell me the impedance load of each injector

Injectors also came with a nice little 'how to fit' instruction sheet ...

they are physically in good condition, with all new o-rings, and are physically clean looking

I would deffo recommend this company to others http://www.deatschwerks.com/products.html

they respond to emails quickly, and the whole thing has been hassle free !

now to fit them, and get the pfc tuned ...

will post up results as and when i have them

Yeh?? Thats bloody cheap, where from.  I think from memory somebody on SAU said those injectors 'sard 550s' can be a bit of a bitch to fit onto the RB25.

they are a straight swap and easy to fit so i have heard.they need collars to make them fit properly,other than that it doent take much more effort than say fitting a set of nismo 555cc injectors.

currently running .9 bar, with these in, and the pfc, well .. who knows, depends on what the dyno guy can get out of the engine ... but i'm not really limited on boost at the moment with eh gcg highflow ... reading up, 1.2bar seems to be the max for std internals, so i guess maybe 1.1bar ... all depends on the dyno and the pfc

will post results when i have them !

How's this going?

Just an info I received from them about these injectors

the RB25 injectors are the same fitment as SR20

injectors. the injectors will fit both without any

modification (direct swaps). They are high-flowed

JECS (OEM nissan) which have been completely rebuilt,

tested, and matched.

i have NO idea on the flow pattern etc - i can only tell you that my mechanic fitted them yesterday, and they slotted into the RB25 head with ZERO problems. They were a direct replacement !

pfc was installed and tuned at the same time, but is not fully finished yet, currently making 212rwkw on a dyno that reads TRUE kw, not a rosy looking kw figure, aparently ...

anyway, should be getting the car back either tonight or tomorrow and will have more info then.

the tuner seemed quite happy that the injectors were doing the job they needed to do perfectly well ...

cheers

A reply I got from David of deatschwerks:

The spray pattern is different, anyone that tells you

otherwise is not being honest. I have had 3 different

injector technicians flow test them and they all said

they are fine. It is a stock conical pattern but the

spray is tigher than stock. This is true of any

larger than stock injectors. In addition, I run these

in my car and my local customers' cars. None of us

have had idle problems or loss of fuel economy. I

also have a steady 14-15 AFR at an 850rpm idle.

Either way it seems like the set tang0 bought are working fine in his car

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
