Definitive Guide To Building 300-330awkw Gt-r

Done the sneaky mod haha

Does help get rid of the shuffling at low throttle %s

A member on here craved is his name did mine

You shouldn't have any shuffle issues with -9 or -7s

If you do, there are other issues.

[Sinista32]

-7's no shuffle

It does smooth out the airflow of the 2 turbo outlets though.... that's why nismo have a piping kit that does the same thing.

Okay drag day 2011, lined up Sloane 7 times and beat him every time....I had, stock 26, -9's running 290-300AWKW full tank 1600 odd kgs, he had 32GTR 347AWKW, cams, turbos similar to 2530's but a bit laggier, nismo copper twin, and weighed 116KG less than my 34.

I beat him because the -9's came on earlier when launching off the line and came onto boost faster after changing gears. Even with his lighter, more powerfull car he got beat. The video shows that area under the curve. Peak power is easy....

I smiled when he said he couldn't believe I kept beating him and said the numbers just don't add up. I explained and he understood.

Now he's going -5's for that higher HP goal, I'm building his new engine, still a stock stroke RB26DETT, so I guess he might be better off now with the -5's but it still won't be as responsive....each to their own I guess.

I'll aim for 330WKW at 20-22PSI once new twin plate and tune done and see where we stand.

[R31Nismoid]

You beat him due to gearing mainly.

Put both setups in a 32GTR, or 34, the most power will win if drivers are equal.

-7's no shuffle

-5's no shuffle

Average power win's in most cases and you have proved it even on the drag strip. Some people just dont understand this. The 'peaky' curve feels faster, but isn't in the real world. RP cars are a classic example of this.

You know @ Drags it's a different story!

The ONLY reason i was faster than you @ Drag Battle was because i was doing 1.5-1.6 60fts. Otherwise even with your laggy setup, you would have pegged me with ~40rwkw more.

Cannot beat outright power in that situation.

In the semi's? I was running on 5 cyl. It feels like it takes away 150kw. I just watched you walk away. So shit. Here we are on DVD and I loose to you! haha . Great weekend either way!

[Piggaz]

Still.. I had 5 MPH over you.... what did you have that weekend? 380? I only had 400.

Dunno?

Just remember you reeling me in, could hear you coming. If there was another 100m, you would've gone past me easily IMO.

I reckon i had ~360 given the MPH, which you had 6-7 MPH more than me depending.

I think I trapped 130 or 131.

We even went into town to get fresh plugs. That shit town had nothing. Thing to remember, always carry small crap like that!

Hi Guys,

Wondering if i can get some assistance with Injector choice.

have been suggested to get the ID1000cc injectors for smooth idle and niceness. Have also found guys selling them for like around $650, $700 shipped.

- have read a lot that these dont fit straight into a stock fuel rail which is what im running currently.

had a look at bosch 800cc which say they are drop in fit for stock rail. again about $700

Sard 800cc, people say the 700cc are drop in however when you go to the 800cc they dont drop straight in.

Nismo 700cc - 800cc. these are suppose to be direct fit.

Is anyone able to give me some good information/advice. Everyone speaks highly of the ID1000 injectors but are they gonna be a pain in the ass to fit?? im only going for the -7s setup on stock Rb with supportin mods for whatever over 300 i can get, currently around 290 on 18psi.

Do i need the 800cc's or should i go for a 700 or there around abouts?

I want something that is gonna be best for price (obviously the more i save the better) that is direct fitment or near abouts (little modification) to fit my stock fuel rail.

Have also seen quite a few second hand sets getting around been used for like less thatn 5000km have flow charts etc. Is this a worthy option for the $400 odd price range, have seen HKS, Greddy 700cc, bosch 800cc, etc available.

Cheers

Are your injectors maxed out currently?

If so, just up the rail pressure a bit. Will cost for 1/10th the price it'll cost to upgrade injectors and then the full re-tune etc.

Realistically you'll only get another 10-20rwkw so no point spending another $1500 on injectors/retuning for that return. You probably wont even notice the extra power realistically.

Not sure as to limits of injectors. They are still stock ones.

have read through all the guides/setups/power rating posts. that injectors will need to be upgraded, whether its as far as 800cc/ID1000cc. at least the bump up to 640cc was required to get more from the tune.

upping the rail pressure on stock injectors? will that work for dash 7's over 300kw. I am already going in for a tune and having more things added, the injectors was one of the things i had budgeted for.

thanks for your help.

[R31Nismoid]

I made 340rwkw on stock injectors with a rail pressure increase, on stock injectors.

It's obviously not "the best" solution, however for your application, given you are almost at the turbos limit anway... Spend $100 or spend $1500 for the same end result - your call really. IMO it's a waste of your money going aftermarket injectors.

If you dont even know if your stock injectors are on their limits - then why are you even looking at aftermarket ones? Talk to your tuner and understand where your car is at first.

[JD32R]

Thanks for the advice.

Obviously anywhere i can squeeze a few $$ is gonna benefit me. Will have a talk with the tuner and see what they recommend.

Thanks mate.

Hot day, slipping clutch....12.001

Sard 700's have the correct plug and will fit straight into the stock rail.

Sard 800's have the wrong plug (but they are included) and might fit straight into the stock rail
