I'm interested... Need to sort some funds out, but if the timing is right I'm definitely on the list to get some of these..

Hey Guys,  

ive organised some sweet prices on a set of 6 x 540cc injectors which are straight fit into the rb25det fuel rail.  

These injectors are high impedence, side feed and same size as stock, so no problems in fitting. They are manufactured by Hitachi Unisia Jecs(same manufacturer for Original injectors for many Subaru cars, STi, Nissan, Nismo, Apexi, HKS, Power enterprise..etc)

The clips are slightly different, and either can be modified quite easily ive been told to fit into our plugs, or we can purchase correct plugs from mitsu electric.

These are ultra atomization technology injectors that assure the very fine atomization of fuel, making your idle stable and providing impressive fuel efficiency.

The injectors flow:

470cc/min at 38psi (standard fuel pressure)

500cc/min at 45psi

540cc/min at 52psi

575cc/min at 60psi

What this means is that to get the correct cc out of them, you will also need an adjustable fuel pressure regulator, but I have been assured the injectors are designed to run this amount of pressure, so they will be fine.

Retail Price on these are $1060 for 6.

If i can organise 10 sets, then the price is $520 = postage ($10 approx?)

So comon guys, this is our chance of gettin injectors finally cheap. Excellent quality injectors made by the same companies as the more expensive ones.

Beautiful timing, put me on the list as a definite (assuming, of course, that all technical stuff is easily resolvable. :cool: )

Only need one more and thats the ten. :P

Count me in.

This is a fine price for direct fitters.Enrico can you tell us if the plugs are a fit or not.

Give me your email so i can contact you.

Like i said im not closin the group buy til next month, + if we get more ill try get more off the price...

Im still waiting for info on the plugs guys.

Are there any other questions needed to be asked?

Enrico - You'll be able to easily answer this one for me. I have stock fuel system running on my R33.. When I want to install these and have them running at an optimum rate, will i need to get a fuel pump and upgrade my fuel rail, or just the case of installing a fuel regulator?

I've always been confused on this point... Otherwise sounds good.

The fuel injectors can flow 470cc at stock 38psi fuel pressure. U will not need to modify anything to fit them, however it is very unlikely that the stock Fuel pump can flow that much though. Therefore to get full usuage out of these injectos, u would need to purchase a bigger fuel pump aswell, so that it can flow enough fuel to the injectors

Hope that makes sense.

Enrico, I was looking at installing these myself and there are a couple of consumable parts that need to be replaced such as o rings and insulators when the old ones come off.

Would you know where I could get these from?

Are you going to have these parts installed or do it yourself?

PM sent

Trust33:

These injectors are brand new, and disigned to fit in the std RB25det fuel rail

ie: High impedance, side mounted.

NOTE: I do not believe that the std ecu (alone) can handle these injectors. You may need a "piggyback" unit or an aftermarket engine management.

Enrico:

Is your contact/supplier able to supply 700cc (or greater) LOW impedance, side mounted injectors?

Just that i am running a wolf 3d and low impedance injectors pulse quicker than high impedance, when idling. The wolf can easily controll both, i just prefer the advantages of the low impedance.

i will find out for u Al.

Im still waitin on the info about the clips and plugs.

Also Im not sure whether the stock ECU can handle these so its best u do ur own research. However if u were still using the Stock ECU id think there would be no need for aftermarket injectors.

Correctomundo!

People with stock ECU and even S-AFC should tread carefully.

It works but it won't work as good as people make it out to be.

Fully programmable ECU is what you need.

Once you go 550cc/AFM, it's time to think ECU.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.

    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
