  1. Mk2 Turbo & Intercooler
    I am having issue with boost on my standard ST. I am finding this scenario now and again, getting more often now: I put my foot down and the car pulls but the boost gauge sticks at 1/4, if I let off the accelerator and then kick it back down boost climbs as normal to between 1/2 and 3/4 (I...
  2. Mk2 Turbo & Intercooler
    Hi there. So I just did an intercooler upgrade and what I noticed when the stock one was removed, it had some oil on the tubes (mostly passenger side/I have a left hand drive car). There was no oil dripping out of the IC, but I could feel some dried out oil with my finger inside the IC itself...

  4. Mk2 Turbo & Intercooler
    Hey guys! I've been lurking on the forums for a good while and I've really enjoyed the wealth of knowledge and it's finally time for me to make a post of my own haha. Yesterday I was feeling a bit adventurous and decided to block off the vacuum hose to the inlet plenum from the recirc valve to...

  7. Mk2 Turbo & Intercooler
    Hello. So i`m having this strange boost pressure problem. The car is a `09 and only modifications are bsr remap and turbosmat recirc. I have the very common problem with 1/4 or 0.3 bar boost pressure to the dial. Sometimes when flooring it at 5th or 6th gear the pressure rises almost to normal...
  8. Mk2 Engine, Exhaust and Induction
    Afternoon Peeps, The other week i finally got around to changing my old standard boost hoses for the Pro-Hose set including a symposer delete (which was a b*****d of a job!) (DSCi map, Stage 1 I/C & CAIS already fitted for a few months) Since changing the hoses the boosting has developed a...

  10. Mk2 Turbo & Intercooler
    So recently I've been having an intermittent issue with the ST loosing the turbo dump chatter and only boosting half way. The spool also sounds higher pitched as well. It seems to come and go as it pleases so I'm at a loss really, any ideas anyone? FYI it has a turbosmart compact recirc valve.

  13. Mk2 Turbo & Intercooler
    So when I lift off after full boost I get a nice puff of blue smoke out of the exhaust (Only happens in high gears). I also have the P0299 under boost code and there was a small oil slick under my car when I came back to it today (Oil level has gone down over a third over a few hundred miles)...

    Hey guys I've got a focus st mk2 apart from removing the symposer when I first bought it I've made no other modifications and it has no map. In the past few weeks it's started boosting well over 3 quarters on the gauge and then cuts out as if it's doing some over boost protection thing. Any way...

  16. Mk2 Engine, Exhaust and Induction
    Hi guys, I've noticed that when i first turn the car on in the mornings there is a slight squeak. this noise continues when the engine is under load. I assume that it loose manifold bolts are causing this. Could anyone help me out with how to tighten these bolts when all I have to hand is a...
  17. Mk2 Turbo & Intercooler
    Hi, I've taken the ST out today and it's only getting up to the first boost marker on throttle and then a little flick past the first mark when I let off the pedal (only boosting to halfway to where it normally goes). It's a 57 and standard apart from de-res. I've had a quick look and can't see...
  18. Mk2 Turbo & Intercooler
    Hi Guys I've blown the seals on my turbo and it's now off the car. I was wondering if any of you have experience with replacing the internals with a Billet Compressor? I don't want to go full hybrid system, but it's not much more to go Billet. Does anyone know the actual benefits of doing...
