Looking To Buy A Gt3076r Turbo Iw

[charlie25T]

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

[silva33]

600cc injectors shouldnt max out at 270rwkw... I think there may be something else wrong with it.

[crack]

740cc will get you to 370rwkw. pm r31nismoid for details.

Get your car checked.

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

They will go heaps furthere than that, more like 450rwkw

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....

[180or200]

also might help if you tell us what the percentage's are in the airflow setting??

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?

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

[Dragonforce]

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?

Sorry for all the question!

Cheers mate

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.

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.
