Need help with mods!!!

Dear friends

I need some advice regarding the HKS GT2530 turbo.

My current setup is as follows---

fuel system: Stock fuel pump

Stock injectors

Stock fuel pressure regulator

Splitfire coils

Platinum spark plugs regapped at 0.9mm

Induction: Stock afm

HKS airpod

600x300x100 FMIC

GFB bleed valve (at stock boost)

Drivetrain: Xtreme heavy duty clutch

exhaust system: HKS 3' dump pipe and front pipe

3' high flow cat

5Zigen 3' cat back with 5' muffler tip

Engine management: Stock ECU

I am currently on a tight budget. However, I previously bought a HKS 2530 kit with actuator and have it lying around in my room. I have been itching to bolt it on my car.

In about 3 months time when I will have the money, I am planning to install a Z32 afm, GTR fuel pump, Greddy Profec B spec 2 boost controller, Apexi Power FC.

The thing is......NOW, I want to install the turbo so i will not have it lying around and taking up space. i can then sell my stock turbo to make some cash. However, this turbo install will be done without the power FC ,Z32, boost control, fuel pump and fpr. I will then be running stock boost on the HKS turbo for 3 months till I can upgrade the rest.

Tell me what you think......will it work out.....Really need advice!

Cheers,

Your fren

Dan

get the powerfc, z32, fuel pump, afm, boost controller (a real one) at the same time

it will cost you more to keep going back and getting it tuned and fitted each time

the gt2530 is pretty small and your paying for the hks brand label. you could get a bigger garrett for similar price. also stock clutch will be useless for a 2530, slip city. the stock clutch is average aroudn 200rwkw which you should crank with the 2530. the 2530 and the hks 25 series have been superceeded by the new hks pro range such as the hks gt-ss and hks gt-rs if you wanna stay with hks label. hks gt-rs on rb25 should net you around 260rwkw fuilly tuned. but youll need injectors as well. stock injectors start maxing out about 180rwkw. then it becomes unsafe. having said that answer your original question

>> However, as I am under tight financial constrains and still want to change my turbo badly!!!

turbo is generally the last thing to upgrade as all the stock components get maxed out as soon as you go over the stock turbo power levels

>> I was thinking of bolting on a T3 flanged HKS GT2530 onto my turboback zorst to replace the stock turbo.

what size exhaust is it? hiflow cat? do u have a 3" dump and front pipe? by turboback i hope you mean dump/front 3" hiflow cat 3" and then 3" from there onwards. 2530 will bolt on to your stock stuff and you can swap actuators so minimum boost is 0.50bar. however your fuel pump, afm, injectors, clutch etc will be at their max capcity.

>>I will then have enough money for a Power FC, Fuel pump, Z32 sfm and tuning.

you can do this, look into hks-gtrs or a garrest gt28 (thats what the gt-rs is but without the hks price and label attached).

opps for got to mention....I do have an Xtreme heavy duty clutch. And Yes my exhaust is a 5Zigen 3 inch catback, with 3 inch high flow cat, 3inch HKS frontpipe and dump pipe and 5' muffler tip(for the look ) .

I have seen peopel on this forum managing 220 rwkw with the HKS 2530 with stock injectors. So i think it should be ok.

I actually have a GTR fuel pump and Z32 afm lying around in my room. However, i thought that these should only be used CONCURRENTLY with a power FC as the stock ECU will not be able to manage these.

Can someone please advice.

Cheers

Just upgrade your fuel pump and you could still pump out some decent figures even without z32 afm, injectors, or PFC. Your current setup plus fuel pump should get you over 230rwkw without any hassles.

Installing the fuel pump will be fine without needing management.

Are you saying I can go ahead with the turbo install?? But just install fuel pump as well??

Thanks

Yes he is.

I would install the turbo and fuel pump then take it to a dyno and turn the boost up as far as works for it.

If you put in a fuel reg. you can up the fuel pressure a bit too.

Hang on there.....That means installing a HKS 2530 with fuel pump and without the power FC???

U guys sure thats ok??

YES, 2530 + GTR fuel pump + Nismo bolt on fuel pressure regulator (Nengun $150) = OK.

BUT (there is always a but), check it carefully on the dyno, adjust the fuel pressure to keep the A/F ratios OK and listen for any knock. Adjust the boost and the base ignition timing (with the CAS) to achieve the best COMPROMISE.

DON'T bolt it on and go for a thrash.

Please post up the results, to prove it works.
