R32 Gtr- How Much Power To Expect?

[gtovr4]

Hi everyone,

I have an R32 GTR with the following mods:

Fully rebuilt engine, CP pistons, n1 crank, stregthened rods etc etc.

n1 turbos (AR 60/64 I believe.)

Power Fc (not fitted yet.)

Stock AFMs, Stock Injectors, Stock fuel pump.

Excedy HD Clutch.

How much power should I hope for?

I'm not hoping for big power, but hopefully enough to notice a difference.

I am noob at this, so how much should it cost me to tune?

Also what should I upgrade next if I want to shoot for more power? (I'm thinking injectors?)

Thank you.

Injectors will hold you back, as with the fuel pump would be worth changing before the injectors.

n1 cranks dont exist.

and check the turbos again they are the larger ones you mentioned.

[gtovr4]

Thanks for the advice. So change fuel pump next and then injectors.

LOL really??

I was told and have a receipt that says N1 crank?

Oh well must be a new stock crank?

Still would like info on expected power and cost of tuning anyone.

350-380HP @15-18PSI, depending on the tune state.

Cool thanks mate.

So that's around 260-280kw atw?

Now the final question remains. How much should I pay for a tune & service?

And does anybody no a good place in Melbourne, in the Northern or Western suburbs?

[Bumblebee]

not enough thats for sure!

Northern suburbs go for CREATD motorsport; fantastic tuning by Rob on my r34 gtr vspec 2.

500bux for a full 4wd tune.

if you truely have n1 turbos you will make close to 300awkw as my car made 255awkw with only stockers, ebc, catback and pods.

make sure you run your engine in first though!!!

you wont be disapointed if you go to CREATD; i was blown away with the modern equipment and best service ive ever recieved at a tuner.

Thanks mate.

Did the 500 include a service as well, or just the tune? Seems a bit pricey?

yeah engine was run in ages ago, just haven't had time to get it tuned.

And yeah they are n1s 100%.

Tunes can go above the $1000 mark.

No, tunes dont include servicing

They are the larger N1 turbos (if youve got the housing etc right)

They will make a LOT more than 380hp/300rwkw or whatever other figure was listed here

Your talking upwards of 350rwkw with the .64's... although they are fairly laggy and not great in the response department unfortunately (better turbos for the job can be purchased)

Tune = $600 minimum (does not include service). Just the tune.

hmmm are they physically/visually any different to standard turbos? They looked very similar to standard turbos from memory.....

The reason I have doubts about the housing is because when I bought them I was told 300-330rwkw max is would I could expect AND that they aren't laggy at all for that sort of power application. I'm sort of hoping they are the smaller n1s now!

I have a pic of them before I put them in the car, I will post it up when I find it.

Thanks for all the info everyrone, you have been most helpful.

Pics of n1 turbos, they big or small??:

[jay1]

good post

[Beer Baron]

well if the turbos are the .60/.64 N1s then sure 350kw + is possible. but your standard injectors and standard AFMS means you are stuck under 280rwkw with any levely of safety until you get bigger fuel pump, bigger injectors and upgraded AFMS.

[gtovr4]

Yep cool. But are they the bigger ones? Can anyone tell from the pics I posted earlier???

Come on tech guys! Surely someone can tell if they're the bigguns or the smalls?

[Beer Baron]

well you've obscured the A/R number on the exhaust housing, and it's not visible on the compressor pic either. so a bit hard to tell.

[R31Nismoid]

part #'s on the cartridge will tell

(and the plug that ID into the search, will come up easily)
