I had the exact same Fuel gear (700cc + 044 in tank + nismo reg) back in the day

Maxed out @ 365awkw @ CRD

You will definitely need to upgrade for 400awkw +

800cc will be fine.. I will be using them for 400rwkw no dramas. 700's will get near on 400 with a minor rail pressure increase

could have searched :P

ok - i will upgrade my injectors to 800cc or more

how about my fuel pump, is it enough? i really dont want to run an external surge tank with an eloborate fuel system in the boot (just more reason for police to pick on me) as i want my setup to look as standard as possible

Even if you go for 1000cc injectors, the fuel pump will be the bottleneck.

To not run a surge tank in the boot there are a couple of options;

-Put the surge tank somewhere else

-Run the second pump intank (this is a bit of fu(king around though)

intank 044 and 800cc injectors made 430rwkw on my old gtr

intank 044 and 700cc made over 450rwkw in another gtr over here

just need to make sure your getting full voltage to fuel pump

that is interesting - i'll speak to my tuner tomorrow for confirmation

less headache for me if i kept my fuel system as is :P

Previous owner of my car maxed out 700 CC sards at 1.6 bar on GT RS's (I think) . Went to 800 CC sards and its fine.... Still using single in tank Nismo pump. Get the 800's! :) It might be worth throwing a fuel pressure gauge to make sure its staying rock solid up top.

I've got an external 044 and 700's with over 400rwkw, original tuner said it was unsafe (inj. duty cycle) and recommended I upgrade before hitting the track - second tuner said it was fine. Both are well respected so obviously your going to get different answers!

Personally I'd prefer the headroom and will be going bigger.

800cc injetors

023 intank bosch pump 800hp(new on the market) looks like the 040 with the filter on the bottom

and run new 1/2inch fuel lines (12.7mm)

and adj reg

maybe upgrade fuel rail

if that doesnt work. go for a 1200hp holly fuel pump with 1inch lines and 1000cc injetors :cool:

get ur setup right and u wont need a surge tank

I just bought 2 044's

But i have a tomei rail 800cc sards

and still need to buy a reg..

going to do a surge tank setup tho.

Dude, you NEED to see my car before you go down that path

have you guys had much to do with the bosch 1000cc injectors or better stick with sard?

i thought that bosch own sard?

siemens injectors, best spray pattern, no offence to every1 runing sards, but compared to siemens they are like a fire hydrant

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
