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

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

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?

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

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?

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 :rofl:

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 :D

edit - good tuner? where are you located?

    • What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!
    • Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !  
    • Thanks, will do that.  Thankfully they still feel great.
    • Yeah man, absolutely. You can try pushing me all the way in swapping the R34 for an E9x M3 
    • It's almost certainly going to be some amount of pads compound transfer onto the rotors. It will probably go away after you've run them for a bit. If not, pull it all out, lightly sand the rotors, scuff the pads, and rebed.
