R33 Gtst 250rwkw Gt30r

[mass_iv]

hi guys my cars currently at the workshop undergoing an operation u could call it, its having a new fuel pump wacked in with a FPR, a new set of injectors, an A'Pexi power FC, and a new Garrett GT30R turbo, so after a tune it should psh about 250rwkw, i have all basic mod's FMIC, air filter and exhaust...

i was just wondering wat u guys think it would run down the 1/4mile, i was thinking low 12's maybe high 11's, is this realistic? any thoughts and comments are welcome..

you'll need some wide rubber if its street gear to get 11's IMO.

i skimped through @ 12.1 and that was ~300rwkw on the old motor... 25/GT30.

The most retarded amount of wheelspin as i was using 225 street tyres

[mass_iv]

yeh ive got 255 street tyres but i was thinking getting some slicks, but im not sure as 255's are pretty wide?

[fragz013]

My gtst is pumpin out 315rwkw has done 11.6 down the 1\4 with a slow start so yea maybe mid to low 12s

[mass_iv]

Im going to be running 14 psi, would i be looking at 250+rwkw? more or less power anyone?

[paulr33]

my gtst with 255s on the rear spins in first gear with the stock turbo so you'd be struggling a fair bit at that power level one would imagine unless its laggy a lot

[paulr33]

youll be on boarder line of the stock airflow meter also no clutch in the list... you have a heavy duty one already yeah ?

[R31Nismoid]

depends on the turbo what power it will make on any given psi

[mass_iv]

yeh already got a clutch and i know mine spun in first before the upgrade, about the airflow meter, i was thinking of getting a z32, but am not sure if ill need it does anyone know wat the limits are on the standard AFM?

[Ruffels]

standard afm will give up around 210rear wheel kw mark im led to belive

could be wrong

shite im going to need to get me a new one, wats a z32 worth new? coz my mate can make me up a custom one for $300, is it worth it or should i go for a z32?

[R31Nismoid]

custom AFM?

get a Z32 and save the hassle. Buy a new one, not one thats near on 10+ years old now.

$440 from nengun

[mass_iv]

yeh custom as in made specially for me, wow $440 is pretty expensive, i think i might get my mates he is known for supplying good stuff....

[TTT]

what suspension mods you got?

how come no-one talks/asks about what suspension mods are required for drag racing?

LOL at 300rwkw and 225's...

[mass_iv]

ive got damper adjustable shocks at front and back, not sure wat brand, but my car sits pretty low. so im not sure wat to set them to wen draging but, hey i guess i can muck around a little on the day make it softer or harder!!!!

<{POST_SNAPBACK}>

Go softer so your car can squat down on the launch, and let your tyre pressure down quite a bit for better traction.

I would go the Z32 AFM as there is the option to select that airflow meter built into the Power FC, which will make the tuning process a little easier. When making that sort of power I think you are better of sticking with a product you know works.

Good luck at the drags, I'd say a low 12 is on the cards.

but what do you mean by custom ?

Spend the money on a new one mate. You wont regret it in the long run.

After all the mods you've done, turbo injectors etc. Ifm your saying $440 for a new AFM is expensive then its time to sell the car

[mass_iv]

i wasnt saying $440 is expensive i was thinking that the custom made one is probably a better flowing AFM then a z32, which means i have no limits in the future if i decide to push for more power.... and as PHATGTR said i porb will go for a z32 as i have a power FC and if it makes tuning easier then i will get it...

[R31Nismoid]

im still struggling to understand though.

how can a "custom" one flow more?

What is custom about it?

Hows does it work with a PowerFC?

Is it a Z32 thats copped up? How would the resolution go on this "custom" AFM?

just interested

[mass_iv]

that is a good question which i am looking into, as far as power FC is concerned the guy that can supply me with one, is tuning my power FC so it is obviously compatible.....
