Single Vs Twins

[ali-turko]

hey guys

i just got few quick questions, my mate has just built a 400awkw gtr with a t04z and he took me for a spin,

i was pretty amazed he had full boost by 4500rpm (26psi), and the thing felt so aggressive, the boost just came on hard,

now my question is will twins come on that hard cause, the feeling was unbelievable,

i was thinking hks 2530s, the car will be a weekend street car and will see the drag strip 2 or 3 time a year

thx guys

2530's wont come on as hard as that T04Z.

Has your mate got a stroker of anysort? That may explain the earlish spool up of the T04Z.

What are your engine specs... It will make things a bit easier.

[ali-turko]

nar his car isnt a stroker, just has the usual supporting mods, forged piston,rods cams ect...

and my motor is currently been rebuilt

do u know wat size exhaust housing his got on this t04z? i was so close to running a T04z on my GTR as well even bought the turbo and i went with the divided twin scroll .70 exhaust housing option for that extra response

i ended up just down sizing the turbo and going with a GT35 series turbo, it wasnt able to make the same amount of power as the T04z would but i wasnt looking for 400kw so it didnt matter

find out wat exhaust housing his got

[ali-turko]

i think it was .84

[luke20t]

is the t04z a garrett or hks item?

[R338OY]

HKS.

But who can tell the difference between the companies these days?

[Tomek]

Tell me if im wrong.. but i could of sworn i've seen them garrett stamped

[discopotato03]

With T04Z's it's all in the housings , and yes they do make a difference .

Those cartridges are all made by Garrett Japan .

I have had both a To4z and now twin garret 2860-5's on my gtr (standard displacement).

To answer your question, as far as garret 2860-5's twins go, no they will not come on as hard compared to the TO4z.

What power output are you aiming for?

[ali-turko]

im after 400awkw or there abouts

but im in love with the aggressive feel of the t04z, and my mate has an hks unit, i wass think of getting the garrett version as it is all most half the price

little confused here, the gt35 will go 400rwkw... t04z is 450rwkw+ territory

way I see it is the 2530's sit somewhere in between the gt35 and t04z, either way its going to make stomping power and be making boost (ie making power) somewhere between 4300 and 5000 depending on your setup

im talking bout 400awkw not rear wheel would that make near on 450 at the rear treads

[Crans]

Comming on small twins or 1 bigger girl. Id go the twins.

Speaking of turbos probably go the bigger single

[Sydneykid]

the thing felt so aggressive, the boost just came on hard

So what you are saying is you like the TRANSITION from lack of power to lots of power? Not the lots of power ITSELF?

Then an even bigger turbo would be better, even LESS power then a much more potent transition to even MORE power. That would feel better to you?

Personally I prefer progressive power as I find the sharp transition makes the car very hard to drive fast. So the 2530's would be my choice, as they have been for many years.

Each to his own.

Im going to be a smart arse so dont take this too seriously...

If you dont want heaps of power but like that serious boost kick, fit 2530's or similar and build in a valve that redirects all boost until it closes at say 5000rpm. So your turbos will still build boost as the car revs, but it all goes to waste, then at 5000rpm bang, instant 18psi or what ever you want. Probably loads of problems in what ive just described, but would be one hell of a kick going from no power to serious power.

Very silly i know

gtr run in awd and rwd = sfa difference dude

[luke20t]

gtr run in awd and rwd = sfa difference dude

theres about 5% difference at most.

next time my cars on the dyno ill try it..

waiting for the new turbo to arrive first!

if the cars got twins already, just stick with them i recon and go 2530's or similar

Couldnt an EBC be setup in a similar fashion?

[Bumblebee]

GT2530s dont kick hard??? how many of u guys have seen the Mines GTR in action??

as far as i could see.. .having the think rev from 4k to 9k in like a split second is pretty fkn hard...

the dude is like into 5th gear screamin towards the redline in no time!

responsiveness and power.. id got 2530.. but im after a lil more power so im going gt2876r x2
