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 never claimed to be an expert. Discussing this with you seems pointless since you have nothing of substance to argue with. Everyone please continue to buy 740cc injectors, it's the easiest advice to give.

OP, apologies for clogging the thread up.

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?

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

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.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?

      Blow Off Valve Is Causing Car To Stall!

      Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.

      I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
