Hey guys i need some help i just got home now and i have a problem, i pushed my R33 gtst tonight and was a cold night but i noticed that first my turbo will debate on weather it will push and kick in but then i later noticed it didnt kick in at all and my motor was doing all the work im running 12psi and have a hybrid intercooler also the car was dyno tuned 2 weeks ago and was running like gold also if i cool it down for 15 mins it runs fine then starts again with the turbo not kicking in its not leaking any boost, it holds boost but just wont push is it the heat??? or what could it be? HELP!!!!

sounds like stock ecu boost cut. turn the boost down a little and try again,. if its a crappy bleed vavle then its just over spiking from the cold weather cos the air is more condensed. the bleed valve has no idea how much pressure is going through so it will just run whatever it "width" is set to. if the ecu see's too much airflow from too much then it does a big timinig and fuel cut to protect tiself. 12psi wil definetly hit it with stock ecu, try 10ish

I can't put the finger on the exact problem. But I had a similar thing happen to me. All I needed to do was tighten my pod filter piping and clean my pod filters. Solved my problem but I'm not sure if my solution will solve your problem.

I would take it to your local performance centre ASAP to better diagnose your problem. Best of luck!

      Cold Start Rattling Sound

      By silviaz · Posted

      So my rb is finally having more problems. 2 issues here but I'm here to just to mainly discuss the rattle noise. The other day when I turned on the car and when I take off or go in reverse, there is a temporary rattle noise but when I cruise, boost, idle it's completely fine no rattle whatsoever. I've also done all the servicing, all the health checks you can think of and it all passes with flying colours.  Also the rattle doesn't increase with rpm, it's only at a very certain rpm (slightly above 1,100rpm). My other car also has the same issue every once in a while. Changed the oil recently, no difference. Even took my oil to a lab and everything was quite good surprisingly. Timing belt changed a while ago to. Had the car on the hoist and can't see anything obvious. Tightened a couple of nuts on the exhaust manifold a couple of months ago. 2 different clips uploaded. One of them was supposed to another issue but I'll save that for another time. Thought I'd see if anyone had this same noise before, it's a bit hard to diagnose while it's intermittent. If I'm not mistaken, I think I had this a while back but can't remember exactly. I was thinking if it's doable I'll get someone to hold the throttle cable at 1,100rpm and hopefully it replicates the sound. rb25det rattle only.mp4 rb25det slow start + rattle.mp4

      Yeah I’ll know when I take it for a test drive and I’ll double check the turbos as well when I have a look at it again.  Just thought maybe they might have done something in the head cause it looks like they’ve taken off the rocker covers 🤔 Thanks for your info!

      As Duncan mentioned it's likely a remapped ECU, like the the one listed in the link I post earlier:  https://minkara.carview.co.jp/userid/444260/car/444612/2099320/parts.aspx He quoted 444PS with an unopened engine and twin GT2510s @ 1.1bar boost... sounds about right?
