HKS GT2530 turbo question

[danieltangtc]

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

Im pretty sure as soon as you bolt the turbo on, your air/fuel levels will be all wrong!

I did almost the same thing as you bolted my turbo on, then was too afraid to drive it, so it has sat in the shed ever since. Now i have all the parts on the car, and am waiting on getting it tuned!

I hope that helps!

If you are on a tight budget then do it all at once with one setup and tune charge.. I am in the same boat, i have a HKS 2535 in my room ready to go on but im not going to do it with out the fuel pump injectors and AFM....

Ive been there and done all the mods you want to do. Firstly its not going to run good with the stock computer even with a SAFC. Get a Power FC. Then turn up the boost. Stock fuel pump will handle about 16psi and then will struggle to supply more. i ran 18psi but with the stock fuel pump but it was running lean (12.7-1) in the midrange. Get a GTR pump, there cheap. Put in 19psi and you should get around 230rwkw. Im currently pushing 240rwkw at just over 19psi. Mid range go is very very nice. Pulls like a train.

Personally I'd stick the turbo on, check the A/F ratios and knock on the dyno. Then juggle the boost and ignition timing for the best compromise, don't run it close to the limit. Not perfect, but easily doable.

Does that mean I can bolt the turbo on without the power FC???

The larger turbo will max out the standard AFM.
