Not necessarily, he won't max either the stock injectors or afm with the stock turbo so not much point splashing coin when it isn't needed.

guess so but if the plan is to upgrade to bigger turbo might aswell do it all at once.

As im guessing its not as easy to setup the nistune for injector and afm unlike the pfc

Actually injector and afm swaps couldn't be easier.

For injector swap just enter and old injector cc and the new cc and the nistune software makes all the adjustments for you, just need to do some fine adjustment of the Kconst and latency with a wideband.

AFM is the same, tell the software what the existing AFM is, and what the new AFM is and it makes the changes for you. Once again you just need to do some fine tuning with a wideband.

Just to clarify something, "headers" aren't really an upgrade for turbo cars as it's not as simple as bolting on a set of extractors and off you go.

The standard exhaust manifold is good for up around 300rwkw and generally an aftermarket exhaust manifold is used for a big turbo with an external wastegate.

Your first port of call should be a decent fuel pump and a full, turbo-back exhaust, boost tee (or electronic boost controller) then NIStune and a tune. That should net you close to 200rwkw and you can get used to driving it with some more power. By that stage you'll be needing to get the minor shift kit in to the auto and then you can look for a turbo upgrade.

I can take you for a ride in the wagon if you want, for all intents and purposes the engine is a 34GTT setup, it's just a bit heavier and is 4WD when I want it to be :)

Where about do you live ? Maybe I could bring my car for you to look at ? Haha

Because I think I have an aftermarket exhaust already but not sure what kind or type.It looks like this (ignore my reflection,just washed the car.It looks very shiny haha).

This is what the engine looks like (attached),everything is pretty much stock.Just a podilter,front mount intercooler and the boost set up to 11PSI.

Thanks !

looks like you definitely have a catback exhaust (rear part).

take a photo of the exhaust underneath the car, all the way so we can see how much of the exhaust needs to be done.

I did the full exhaust, intercooler and nistune first and made 190rwkw. This was a great setup. You might be happy here, well at least for a while. Then look at the next step.

I'm in Ashfield mate, just east of the city.

As Harey said, you've already got at least a catback. You've also got a front mount and some more boost, need to sus out whether the fuel pump has been done as well.. kind of hard without pulling it out of the tank!

So really, NIStune and start saving for afm/injectors/turbo.

Plus a hi flow cat and dump pipe most likely.

Chances are the fuel pump is standard. My standard fuel pump was fine even after it was tuned at 190rwkw. The R34 pumps seem to be pretty good and enough for the standard turbo.

Yeah sorry, forgot to say if it's only a cat back then a nice dump/front and a highflow cat needs to go in there too.

As for the fuel pump, I think it's more a case of them not being as old as R32 and R33 pumps but for piece of mind when pushing for more power, needs to be done.

I think I have a full exhaust system but not sure.You guys can be the judge haha.

Here it is...

Looks like a standard front pipe and standard cat.. Jump on justjap.com or similar, and look for a one-piece bellmouth dump/front and a highflow cat (steer clear of cheap Xforce cats).

As for the bodykit.. I believe that's a Z-tune kit.. fkn $_$

Do you where to get a smaller size washer bottle ?

Wanna fit one instead of the stock GT-T bottle (which is bigger) due to having less room after fitting the intercooler kit with cross over pipe.

Nothing off the shelf that I know of but someone like Embleton Engineering should be able to knock you up a neat little ally bottle.

About the same cost to get 250kw as 290 300ish just more lag and different parts eg different turbo, better clutch etc. So you need to decide on your own how much power your going to want and upgrade the usual bits to handle it. Plenty of results/ dyno graphs it the turbo upgrade thread.

Plenty of people asking "what do I need for 250, 280, 300kw etc" and plenty of answers to these questions...

Find these threads and start with the supporting mods first otherwise you will have to pay for twice as many tunes.

Okay,finally after I've installed the Nistune ECU and tuned it.

To start with the modifications,I was thinking to buy all these other supporting items as follows :

Z32 AFM

Sard 650cc Injectors

Walbro 255LPH Fuel Pump

X-Force 3" High Flow Cat

JJR Bellmouth 3" Dump Pipe

Please give me any tips or recommendations that you have before I go ahead with my order ?

Cheers rolleyes.gif

A z32afm reads the airflow and sends the info to the ecu. They are used because they can read more flow than the stock afm.

An Apexi SAFC adjusts the signal from the afm in order to try to acheive better afrs - a task much better left to the nistuned ecu.

Consider getting one of the new Deatschwerks pumps instead of the Walbro.

    • 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.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
    • FYI: Racebox RE7R Custom Tunes Released!   https://goracebox.com/.../2017-infiniti-q50-q60-re7r-tcm...   FOR GEN 2 (21+) VEHICLES, PLEASE SEE NOTE AT BOTTOM See more   But whomever tuned your car is the tuner you should go back to, AMS, Sonictune or BT Tune....
