Will HKS 2530 give me 250rwkw

[Guest INASNT]

Ok i am after a reliable 250rwkw, at the moment i got 185rwkw with the stock turbo at 12psi.

Will the HKS 2530 with 600 x 300 x 76 fmic, s-afc, full 3inch exhaust, catch can, pod give me a reliable 250rwkw with ofcourse upgraded fuel system and possible upgrade to pfc.

Who has done this and with what psi pressure will the turbo need to be run at to produce 250rwkw and how responsive streetable will the package be?

I dont want to do any internal work as yet.

Also is the 2540 the biggest internal gated turbo that will bolt onto the stcok manifold??

Why buy a HKS jobbie?? I have talked to GCG in NSW that will high flow a stock turbo and here is the best part for insurance purposes it the turbo looks stock. By high flowing they replace all the guts. I also talked to one of the blokes at Hills motorsport in NSW yesterday and he says he can rebuild my turbo with all sorts of flash internals.

if you decide on the 2540, I've got one for sale

I have considered rebuilt also, but u can beat the Japs for these kinds of stuff! Any1 that says they can built a turbo to HKS specs is kidding em selves i recon!

how old and how much for the 2540 u got for sale?

I don't know of anyone who has a 2530 that has made 250rwkw. I think a 2540 can do this. I'm sure you could achieve it with a 2530 but I'm not sure how long your turbo would last.

Moanie on this forum has a 2530 with a HKS cooler, upgraded injectors, fuel pump, SAFC, exhaust and pod and maybe a few more little things and she makes around 210-230rwkw I think.

[Guest INASNT]

my aim is for 250rwkw with a low mount turbo. If not the 2530 or 2540 then what will do it?

[R33NT]

Seriously call Mark at Hills in sydney and he will change your mind!

[R33NT]

INASNT quick aside question but what field of engineering are you in????

[kabab]

HKS make the only ture bolt on turbo where everything lines up using ones GCG may bolt up but the oil etc might not so the $$$ you save in getting GCG you are going to spend in labour and parts fitting.

Remember peak power isn't the be all and end all with the 2530 you are going to get a very nice and streetable power band.

[R33NT]

GCG take your standard turbo mill the living hell out of it and insert their own guts. ie they use the standard housing and your telling me that by using the standard housing all of sudden when you bolt it back on nothing will line up?????

By buying a hi flow unit u would be able to to chose the impeller design and as such you can get a large setup which will give you peak power up high or a more streetable package for down low.

I work in mechanical power systems engineering!

I have heard good things of CGC, but for the same price of the rebuilt i can get a HKS item!

[meggala]

inasnt get ahmeds 2540 they are a great turbo and will put you close to the 250 rwkw. only problem with that is you will be to cheap to put injectors power fc and z 32 afm in but you might do it later a very good upgrade for the r33. Ive been in a 2530 equpped r33 it was very nice but not as savage as the 2540

i have heard that the 2540's on a GTR dont run aswell as 2530 for overall response etc!

wondering if it will be the same as for the gts-t!!

And if i get my new job next week i will not have a problem putting in new injectors etc!! (big $$ increase)

I thought you ment a complete replacement turbo not a hi-flow my mistake.

[T0nyGTSt]

Well...

Funny you should mention this.

In my mind the 2530 is more a s15/GT-R turbo.

I'm about to stick a 2540 into my car.

Eventually though I can see the 'full picture'... it won't be as modded as Brendans' or Andrews' respective cars (I don't want to buy a manifold) and I feel that for me, 240/250rwkW should be more than enough. However as a daily driver, reliability is what I need as well.

This how I see my car panning out... (asterisk is what I do not have yet and I feel are perhaps optional)

550cc injectors*

Apex'i cone filter in a fiber box

ARC FMIC

fuel pump* (GTR or Bosch)

HKS BOV

HKS 2540 w/3" dump

Kakimoto full exhaust

Oil catch can*

PowerFC + AVC-R is the brains and up the boost past 16psi

Rising rate regulator* (not a Malpassi)

Z32 AFM*

250rwkW??? I am certain I will pass 250kW with the use of 550cc inj. or too much in the way of boost.

I do not see the need for a custom manifold. Wrong?

tlai909

sweet.

how much boost u recon it will take the 2540 to make 25rwkw with 550ci injectors and tuned properly!

U might also want to get some adj cam gears

[T0nyGTSt]

Hard to say, you need to find out what the max. efficiency of the 2540 is.

It has an A/R of 0.64.

Max. pressure is something like 2.0 or 2.5 bar AFAIK.

I don't think 28 psi is advisable with stock internals

I would think a 18-20-22-24 psi would be fine.

I would use Andrew's car as a guage.

With a GT3040 and 1.2 bar it hit 280rwkW but that's with Z32 AFM, injectors, manifold, all the high fuel bits...

250rwkW might take 22+ psi in all likelihood.

[Guest INASNT]

dont know if u wanna run over 20psi with the stock internals!!

how much did u pick up your 2540 for? if ya dont mind me asking and is it a straight fit exactly? no cutting and chopping required, and can u use the same stock dump pipe?? coz i got a custom 1 with seperate pipes for wastegate and exhaust gases made?

[T0nyGTSt]

Well Andrew did 280kW with stock internals...

LOL

I'm gonna keep my 2540 buy price secret for now...

It is not a straight fit apparently but the people who do my work think that a $50 custom flange will do it.

Mine comes with a dump pipe but I may have to go with a custom like yours because I want that loud external wastegate sound.

I'm am hoping that either my current 3" dump is fine or the one that comes with it is usable.

In the short term I hope I can just get the turbo fitted and running.

T.

[Guest INASNT]

its internal gated isent it?? so u wont get the external eastegate sound!

the main question of running 1.2-1.5 bar over a long period and the amount of damage it will cause the engine is my real issue!

Hasent whatshisname got around 250rwkw with only 13psi?? whats he using
