hi

i bought my r33 GTS-T stock a while ago and have done a bit of modding on it so far but also blew my stock turbo :whoops: so i had it replaced with a HKS GT-RS bolt on ever since ive had it on it whistles like a mofo even with the slightest increase of throttle but thats not the worst part ever since then ive almost lost my boost completely. as soon as it hits about 3000 revs it almost chokes and refuses to go any more so i have to back off, i tried racing my friends stock subaru and had my ass handed to me. but when the boost was needed it somehow felt like neutral. this is really getting to me and i would of thought a turbo upgrade would actually be an "upgrade". i dont want to give up but i do want to fix this so far i havent got the answer i need.

suggestions would be appreciated

stock except for:

front mount intercooler

walbro 400hp fuel pump

splitfire coilpacks

APEXI N1 evol mk2 exhaust

hi-flo cat conv

stainless steel dump+front pipe

GT-RS

APEXI Pod filter

So as you have said in your other thread, you have done everything but the most crucial thing. ECU!!

You can't expect the stock ECU to understand what is going on and hence why it is running like crap. I ran my GT-RS on the stock ECU for a while before I got it tuned so I know what it is like.

So ECU and Injector upgrade time, put some boost into it and you will be amazed at the transformation.

And yes the GT-RS does whistle a lot but they tend to whistle a lot more when they are new. The reason it is sounding so loud is all you can hear is the whistling when you put your foot down, but the car aint going anywhere due to the stock ECU. With a proper ECU and a tune you won't hear the whistling as much over the engine noise.

    • Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...
    • My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.
    • I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.
    • I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended
    • Yeah mate, no probs. Just swap the email addresses?
