Don't get them hiflowed. it ruins the spray pattern and costs nearly as much as getting a good set.

I look at it this way, Injectors are a CRITICAL part of your enging and if they dont work correctly it goes BANG seriously just get good ones to start with. $700 beats a dead engine :laugh: and relative to other mods they are quite cheap.

I disagree, a few places actually highflow injectors correctly and pay attention to multi-port spray patterns, AVO, APS, deatschwerks etc. They work out to be a good option for people with R34's that can't get access to a range of injector sizes. The below injectors suit V35, 350Z and R34 RB25's

what power levels are you chasing?? Stock shoud be fine for around 250 with pump and reg.

I'm after around 240kW at approx 18lbs with fuel pump, avcr, pfc, z32 afm, slide hiflow, fmic, 3" exhaust, filter and possibly cam gears and cams. So besides an fpr being dodgy way of fixing fuel probs the injectors are going to run out flow anyway.

240 on stock should be fine after changing just the pump and reg, check A/F and adjust the reg to fix (and of course your tune timing ect..), I am running 242 with stock pump and reg and stock injectors, I am changing reg and pump this weekend which should fix my 13 to 1 a/f bring it back to 12 to 1.

But if you want to be absoultly safe change them.

so you have 240rwkw with stock injectors just a adjustable fuel regulator and a bigger fuel pump? im also wanting to know what is the best road to take towards injectors? ive got cooler/exhaust/sliding hiflow/splitfires..soon to bolt in z32 afm and powerfc then get a tune on 15psi...my mechanic here can hiflow my injectors for $150..i dunno what to do?

yes that is correct, i am fitting a malpassi rising rate and a walbro this weekend. Why do you guys think you need to change your AFM for or your injectors.... tune it see what it needs instead of buying things you may not need. But like i said if you really want to play it safe get them first before you do lots of tuning then you dont have to constantly keep going back to the dyno if things are not right the first time.

After having injectors hi-flowed by AVO I had my car tuned and have been happy for 2 years now.HOWEVER,I recently did some work to the car and needed to get it retuned so decided to see the Hitman in Penrith.I was amazed when he changed the flow on each injector and I could hear the difference on two of them.They weren`t pulsing correctly.He claims,and I agree that the spray patterns just aren`t right.To be honest,I never felt totally at peace as they were visually different on each hole.Thats four holes per injector by 6 injectors.

So now I`m waiting for my Nengun Nizmo injectors to arrive.I have the feeling I`ll be able to add some more timing due to better spray patterns.Fuel consumpsion will be better to.Thats the theory anyway.By the way,did anybody notice the Deuchewerks RB25 370cc injectors and how you can`t mix them with standard 370cc injectors.Does that tell you something? Obviously the spray patterns would be different and therefore if mixed different cylinders would run rich or lean.

I thought you meant 250hp in an earlier post. 240kW with stock pump/injects its gotta be leaning out like a b1tch, do you run a PFC?

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      By GTSBoy · Posted

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
