Hey man

I have just installed about two months ago a 3076r. i got 271rwkw at 17psi

your 600cc injector might max out at 270rwkw man

you might need bigger injectors or a fuel pressure reg

i have 740cc injector and there at 80% cycle

My clutch had the dick at 270rwkw also

i just bought a Os giken twin plate too.

As for coils. Man you need them as then will miss fire hard

Get your car checked.

I am making 274rwkw @ 15psi on a rb30det, using 550cc and my duty cycle only reaches 72% MAX.

Wow boys nice replies.....................

With those injectors is there a Fuel presusure reg involved..........

I am using 740cc but my fpr isnt really in use ............

My turned name is Dave formally know as Dyno Dave. been tuning for over 20yrs

i believe he has some experiance

Charlie, without trying to start a shit fight or start throwing insults around, please confirm your injector size (don't just tell me they are 740's, take the number 1 plug off and confirm the colour, i'm assuming they are nismo's), the fpr base pressure and the fuel pump and wiring being used. 740's should be capable of a lot more if the rest of the fuel system is up to scratch.

Don't start claiming dave is the greatest tuner ever and what he tells you is gospel. Your results are significantly different to other results so find out why. Do not accept what one guy tells you. Either the dyno is reading low (which i know bel's doesn't) or there is some other issue.

Book in a run with UAS, CRD, Unigroup, JEM, whoever and get a second opinion.

I don't want to labour on duty cycles either, so can you post up the sheet on the result here?

270kW @ ~17psi with a 3076 on an RB25 is fairly typical, and a good stout result.

I saw from one of your posts that you are running an external gate. What manifold is it all bolted to?

Well hell in that case you may as well go and buy some 1500cc injectors so your "experienced" tuner can make 340rwkw @ 79% duty cycle. :)

No one questioned the abilities of your tuner, they are saying that something else may be causing your injectors to run harder; but a good tuner would know that 740cc injectors are good for 400+rwkw, so he should be looking at why your setup requires such a high duty cycle.

I do have an adjustable fpr, but it's currently running std pressure. Once my new engine is run-in, i intend to run more boost and hopefully crack into the 300+rwkw range. It is at this time i plan to see if i could get away with adjusting the fpr; If not i could always buy yours for a very cheap price ;)

That is fair enough.. it is ok not shit fight is starting

I am not saying dave is the best tuner ever

but 20 years experience ..... he must know more than a bit dont you reckon

I have Nismo 740cc (red)

i also have a Sards Fuel reg

Walbro fuel pump

They are capable of doin more.... well except for the fuel pump

Im have a tial wastgate gate off the standard manifold

and i get 17psi at 3500rpm

:(

Ill get my sheets on the comp and ill post them up asap....

Im willing to bet it is your pump and not your injectors i got my car tuned and it showed up around 80% duty cycle with 600cc injectors and was making only 245rwkw with 14psi...changed the pump, finished the tune and it showed 306 rwkw at 18psi and the duty cycle went back down to high 60s

On to the turbo I had a 3076r with a .82 IW rear made 306rwkw at 18psi and 260rwkw at 14psi it was quite responsive though i did have poncams to help, all up it was a nice linear turbo on the street not so much down low that it would wheel spin all over the place and not too laggy

hey mate,

Your 3076 was internally gated? Where did u source it from if u dont mind me asking?

:whistling:

I got my internally gated GT3076R through Slide on these forums.

Here is his new thread, i just happened to see: Slide's Garrett Turbos

hey mate,

:D

I got mine from this man here Elite Racing he was a few hundred dollars less than Slide at the time but i would get a prive from both.

What did you do about water and oil lines? also did it require a spacer plate?

How have you found the internal gate? No boost creep at the higher end? :thumbsup::D

Sorry for all the question!

Cheers mate

water and oil lines can be ordered from the above two guys it did require a small spacer, mine fitted on the manifold...but only by about 1mm so we thought it was best to space it out a little lol. I had a 14psi actuator I had no boost creep at all but if you had a lesser actuator I think you may strike the odd problem

why hasnt your experienced tuner told you that your running out of fuel! and recomended you change pumps?

as i suspected your running a walbro, which is a awesome pump for early stage 1 mods, but once past 250rwkws the walbro run's out of puff. change it soon if you like your bottom end.

Good pick-up

+1 to replace walbro pump.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
