Turbo Upgrade Advice

[ryansr33]

hi,

i recently bought an r33 gtst, that's currently running a hks gt2535, and looking to upgrade to something larger.

i've found a kit for around $800, which includes the following:

Turbo Specs

3" Inlet Diameter : 2" outlet ON FRONT COVER

Wet Floating Bush Bearings: 1/8 NPT oil inlet

T3 Flange : Fits T3 and T3/T4 Manifold

Specs: .50 a/r compressor, .63 a/r turbine, .57 trim

Turbine Wheel: Exducer: 57MM Mayor : 86MM

Compressor Wheel: Exducer: 58MM Mayor : 68.5MM

Rated 600+hp

12 month warranty

Top mount Stainless steel TURBO exhaust Manifold

PRO boost 38mm Wastegate with 9psi spring

just wondering if it's a good deal. any advice?

Cheap shit China crap!

Honestly, you said you just bought the car, enjoy it as it is and get use to it, because if you never owned a hi-powered car before, you current set-up is already lethal.

If you really want to upgrade stick with HKS, Trust, Garrett or Apexi turbos; they are more expensive for a damn good reason.

Having a HKS GT2535, you should be making about 230-240rwkw, provided you have all the right supportive mods, which is heaps for a road car.

Any chance of detailed spec of the car's current mods and maybe a dyno graph?

looks nice but you do get what you pay for

[paulr33]

a decent ball bearing turbocharger should be around $1500 to $2000

a decent manifold should be around $800 to $1000

a decent wastegate should be around $500+

so if your getting everything for $800 - it must be good

[ryansr33]

this is whats been done, i havent had it dynoed yet but its supposed to be running around 321hpatw, on 18psi.

HKS GT2535 Turbo

HKS Super Drager 3.5" Turbo Back Exhaust

Hybrid Front Mount Intercooler

GReddy Inlet Plenum

Nismo 740cc Injectors

Bosch Fuel Pump

Apexi Power FC with Hand Controller

Cusco Front Strut Brace

Oil Catch Can

Heavy Duty Clutch

Apexi Pod

Z32 Airflow Meter

HKS SSQ Blow Off Valve

Blitz SBS i-D Dual Solenoid Electronic Boost Controller

50cm alloy radiator

i thought it sounded to good to be true

any ideas on where to get a good kit from and how much i should spend?

[paulr33]

speak to gcg.com.au and tell them how much power you want to make a 2.5 litre with a T3 flange setup

You should be getting an easy 240-250 on that turbo (same as my one) at 14 psi not 18, I'd get a retune.

You will regret swapping to something else as the 2535 is wicked-awesome for street and spools up nice and quickly.

What sort of power do you want to make (and why?)

a decent ball bearing turbocharger should be around $1500 to $2000

a decent manifold should be around $800 to $1000

a decent wastegate should be around $500+

so if your getting everything for $800 - it must be good

haha summed up pretty well

[ryansr33]

i've got a bit of cash left after buying it so i'm looking to upgrade, and i dont have enough $$$ to do internals, so though turbo was the way to go.

and yeah im pretty sure it needs a tune although it drives really nice, i think its running way to rich, any suggestions on where to take it?

[evil_weevil]

Id just get a retune and enjoy it as is until this turbo dies.

Unless you plan on either doing some serious drag/circuit work - Id keep it as is as people have already said - 230 - 240rwkw is good and plenty of power for fun

Ive just kinda upgraded mine - had a hi-flow with similar mods to you now making 235rwkw but my turbo died, now got an HKS GTRS waiting to go on

edit - good tuner? where are you located?

[ryansr33]

im in WA, bull creek if that helps

ring Mick at ovaboost... if not there are other excellent workshops/tuners like hyperdrive, xspeed etc

That set up you have seems pretty lethal as it is. 320rwhp is a lot of power!
