Aftermarket Ecu For R34 Gt-T

[Kaido_RR]

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.

[Jeremy1607]

Okay,cool !

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...

[Jeremy1607]

How much do you guys think this kind of bodykit would cost ? Lol

[bubba]

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.

[mark33gtst]

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.

[Jeremy1607]

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

[Jeremy1607]

And also what's the difference between a normal Z32 AFM and APEXi SAFC ?

Huh?

[KiwiRS4T]

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.

[Jeremy1607]

I mean what's the difference between AFM and SAFC ?

[KiwiRS4T]

You really do need to use google.

Try "Apexi SAFC"

and "what is an afm"

etc.
