  1. Gen1 1.4L Turbo
    So I have been having an on and off problem with the code P0299 popping up on trips, but like I said occasionally. Over the course of about a month this issue became worse until I decided to just replace the wastegate seeing if it would fix the issue. Somehow I accidentally ripped a tube going...
  2. Gen1 Service Issues
    Hi all! Back in July my turbo went, the exhaust turbine wheel broke completely off the shaft and the car had no power what so ever. The car had about 98K on it. I rebuilt the turbo with a new center section and the car definitely has power now, did an oil change with full synthetic, replaced...

    So I'm asking this question in general because I want input from basically everyone. I recently got a p0299 code which is underboost code. I own a 2nd gen 1.4l turbo cruze, and Im asking if the 1st gen and diesel variants also have experienced this. Reason I think its the wastegate issue in...

    Has anyone ever preloaded their wastegate actuator? Has it caused any problems? Sent from my iPhone using Tapatalk
  5. Gen1 1.4L Turbo
    So I've been having a p0299 (yes another p0299 thread :D ) but my observation is that it only triggers when I hit over 4.5k rpms. I typically clear the code and move on since I don't notice any performance difference. However, I've been looking around and notice a lot of conversation about the...
  6. Gen1 1.4L Turbo
    Has anyone replaced or added anything like this to their 1.4l cruze? Is it difficult to DIY install these? Suggestions on BOV and /or Wastegate?

    Is it plausible to rout the wastegate's air to a secondary, smaller turbo? I notice in my car, the wastegate usually opens between 3 to 4k Rpm. So if it was possible, would I see additional power output at 4k Rpm? How much HP would be feasible to get with a twin turbo on a 1.4liter engine? And...
  8. General Discussion
    Just curious if you'd think it's a good idea to adjust the turbo wastegate to a higher PSI, on the hot weather we're getting here in summer? I hardly ever press the pedal past halfway, even when accelerating on a highway onramp, but 100+F temps do have quite an amount of heat soak. If I do...

  10. Gen1 Service Issues
    While climbing a hill on a road trip I noticed the Cruze lost power about 3/4 up the hill. Cut the a/c and checked the dash, no lights, messages, or abnormal gauge readings. Next hill no power and down to 4th just to get up that one. The turbo seems to be working but does sound like something if...
  11. Gen1 1.4L Turbo
    Hi I'm experiencing the following problem: Before starting the engine and just by turning key to ON position the wastegate solenoid next to the wastegate and under the turbo intake hose starts clicking hard. Here's a video of the sound. (don't be fooled the engine is off, it's just heard by...

    Source: Ebay.com Part of a vehicle's turbocharger system, a wastegate releases built up exhaust gases once it receives a signal from the actuator. Depending on the vehicle, the wastegate may be internal or external. Regardless of the location, the wastegate must open and close in order to...

  14. Gen1 Service Issues
    Hello, I have a 2011 Chevy Cruze LT RS. Great shape and condition until now the P0299 cel kept coming up and soon enough figured out it was the turbo. But im not sure what to do. A new turbo in canada is $800 and the wastegate is about $125.00 (from the dealerships). The car has nooooo power...
  15. Gen1 1.4L Turbo
    May have identified my low boost and poor performance problem. 2012 ltz 51k miles 6at, Low Boost With NO FAULT CODES. Check the video linked below... lots of play at the pin. I told the dealer on my last visit the loaner cruze seemed much faster but they claimed there couldn't be anything...
  16. Gen1 1.4L Turbo
    Hello everyone, so I have a real issue. I installed a CAI and it was running fine for about 30 miles, than a check engine like turned on, and now my idle is jumping up and down, and whenever my car builds boost, I can hear it release all of it and I cannot get it past 2ibs of boost now.. what's...
  17. Gen1 Service Issues
    Car has surged with the turbo since I bought it brand new. 58,000 on it now.. 6 speed manual eco. Now check engine light came on and I got code P0299 - Low boost/underboost. Car had a big lose in power and fuel economy. Dealer just called and said a retaining clip on the waste gate has gone...
  18. Gen1 1.4L Turbo
    Here's the original wastegate length for the 1.4 Turbo. I made the mistake of shortening and lengthening the rod to see if I would get more boost, more boost sooner, more power...etc. and it only causes the computer to compensate for it and cut power and surge and can cause overboost codes...
  19. Gen1 1.4L Turbo
    Poking around the engine compartment of my '12 Eco, I found what appears to be significant corrosion on the wastegate actuator rod where it is exposed to the elements. It's not enough to cause it to fail yet, but it is a concern long term. The rust was advanced enough to be flaky, so I'm...

    This directly from Trifecta: Short version: DON’T DO IT. At this time, Trifecta does NOT ENDORSE NOR RECOMMEND modifying the factory wastegate actuator length. Long version: The wastegate on the 1.4T engine is held closed with spring pressure by a spring that is installed in the wastegate...
