go right ahead then, up your pressure 5psi or 10 psi. Then add the rising rate of 1:1 to it. I run 22psi on some days, hmmm, that would give my standard injectors (if they were still fitted) a good, 20psi+ extra pressure. And people with the stock turbos, gonig from 7psi to 13psi, thats an extra 6psi, plus your claimed 5psi or even 10psi. 10psi to 15psi is not only a lot of pressure, but a lot more flow for these 15yo injectors..

You'd rather risk doing that, and blowing your engine, than getting new, fresh injectors?

Do you know how many GTR's and GTS-T's I have seen with stuffed injectors, running at standard pressure? Oh, but you're the expert. My bad.

I won't tune a car with a malpassi FPR now. I turn them away till they put a stock one back on or get a sard or similar

Last one i had on the dyno had 3 different AFR's on 3 power runs in a row... 11.5 12.5 and 13.5 LOL. those damn italians.. they think they are gods gift to the world.

ALSO i would get rid of that ECU. it is shit. Sorry to break the news to you.

yuck.

The last 2 cars I tuned, we had to take them off and bin them.

The AFR's would be from one extreme to another. You go WOT, the AFR's would go to 11:1, not touch the tune, then WOT again on the next run, 13:1. Put the standard one on, and AFR's would hold perfect.

They are junk.

have you found any info about the latency of your injectors yet chris?>

Nothing that refutes the info my current tune is based off unfortunately. Ah well, loving the flames for the moment! My fuel efficiency sucks though >.<

from what i have heard... but it depends on where you want to take the car...

for the 300 rwkw you mentioned you'll want a better ecu, bigger turbo (hks 3037 pro s or similar), injectors, fuel pump, Z32 afm OR map sensor'd ecu, cams are an option and then you'll be dancing around the limits of the stock engine.

300 rwkw is expensive in gtst form...

stick to 250-280 tops imho

280 is pretty good tho right? hmm alright...

i have heard good things about Power FC and also Wolf seems to have a few ppl happy with it..

what do you guys recommend?

Also will the SARD 550CC injectors do well with the power i want to reach?

Edited by palmer

yeah the 550's will be fine but as previously stated bombtrack is having latency issues with his... they are shooting fuel for too long and makin teh massif flames...

nismo 555's are probbaly the easiest option

power fc > wolf

haltech also a good ecu option...

ok

so get some Nismo 555 injectors, Z32 AFM, maybe some Cams and see how it runs with the EMS Stinger at the moment... if im happy ill leave it... if not sell the Stinger and get a Haltech or the Power FC

what fuel pump would be a good option?

the EMS stinger is a map sensor ecu so you wont need the Z32 AFM.

Just get the injectors turbo and see how you go with your ecu. if you like your engine and want it to last id get something else.

But try your luck. a new engine is only $1500

:D

I post this;

Discussing this with you seems pointless since you have nothing of substance to argue with.

Then you post this. You're blind, and possibly stupid.

I said exactly this about 10 posts back, and agree with you 100% Guilt-Toy, I refuse to tune cars with them installed because they completely waste my time trying to diagnose fuel pressure problems.

Factory ones work fine.

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
