Current setup: AP650 kit just installed, this kit utilize ball bearing garrette turbos and external wastegate

Car has about 22000 miles on it, before installation the car was running on speed gallery 550 hybrid turbo kit. After the install of the 650 kit, the car is pulling stronger and my boost peak at about 1.25 bar at 94 octane. The problem I now have is my right side of the turbo is smoking!! Not a good sign, to me that means some where or some part is burning oil. It happens when i drive around and park for about 10 minutes and start the engine, the right exhaust would puff out blue smoke ( this happens ONLY to the right side turbo or at least coming from right side exhaust ). And when the car is idling from cold start, it will be normal until about 8-10 minutes once engine is warmed up, it will puff out smoke occasionally.

After boosting and driving the on the freeway, no smoke for the first couple of minutes and then smoke puffing out on and off when I have the engine idling and watch behind from the rear.

Dan @ vivid racing is working closely with me to tackle this problem, but I just want to get some more feedbacks from the turbo gurus and see where else the problem may be. Thanks for viewing.

 

Hi.... When you installed the kit did all the parts in factory check valves go back in? I assume that they use the factory tops and tial lower to fit the gt28s'...Tim

 

My installer used the check valve that is sent off by Vivid racing to go on top of the garrette turbos. What do you mean tial lower to fit the gt28?

Thanks.

 

OIl is leaking from some fitting.... no big deal... worst case scenario is that the turbo is blown...

 

Yep, check your oil levels frequently. If the levels start decreasing at a more rapid rate than usual then the fittings may have worked their way loose. It's good practice to retighten everything after the initial install to make sure they are back to torque specs.

Didn't you mention before that due to how the wastegate was misconfigured with the Greddy solenoid that the turbos were heavily overboosting? Over speeding the impellers may also cause the turbos seals to wear prematurely and allow oil leaks to enter the compressor side. Check the compressor side hoses to verify if their are traces of oil.

 

The oil indicator is showing a loss or use of oil, i remembered last week there was 4 bar remaining from the bottom and now there is 3 bar from bottom. In terms of fitting gotten loose, there would be oil stain around the turbo or wastergate but my turbo and wastegate are clean, with no signs of external leak at all. I am sure this is an internal leak somewhere.

And yes EG, the motor was overboosting at one time when we are hooking up the EBC, and as you know there were some error in clarifying to how to hook up the EBC. Anyways, I did a leak down test and there was no damage done to the engine, fortunately. That being said, I have got a new turbo cartridge from vivid and replace the previous catridge that may have broken seal.

 

Turbo is blown, do you mean the seal of the turbo's catridge?

 

Sounds like the turbo is shot. Have Dan send you another turbo...that should solve the problem.

I've heard that Garrett turbos smoke when they go bad...this is caused by oil leaking into the turbine / exhaust and burning...thus the blue smoke.

 

Dan is sending me a turbo catridge to swap out the current one. Do you think this is exchaning the catridge will solve the internal oil leak?

 

My dealer just changed my oil and put too much in. I smoked all the way home. Emabarrasing. That's the last time they change my oil...

 

To my understanding, too much oil will cause the seal to break due to the excessive pressure. By the way, I am wondering if there is a proper way to determine how much oil is to be added.

 

RPM - we use actual Garrett turbos, not the EVO Tial hybrid things. So these are Garrett GT2860rs turbos with the Garret flanges. That is why our kits come with new headers and exhaust adapters.

Our kits include the proper oil reducer that goes into the turbo and between that and the engine block is a check valve that has a 5psi ball/spring mechanism and a steel braided oil line. They need to be tight and tested. Once all installed.

That being said, Ken and I are working out the details. The problem lies on installers not checking there work. Turbos are not shipped bad. If you dont put a fitting in correct or have the turbo clocked a certain way, or even mis install the boost controller, these can cause issues. Unfortunately its hard to find good shops to do work.

RPM since you are in WA, hit Ken up.

 

I really don't understand why some people have to climb over others to get up the ladder? "EVO, Tial Hybrid things?" That is a real mouthful! Are you attempting to disparage EVO, TIAL or both? I really don't get it because both companies have products that exceed in some areas. For anyone to claim they are the cats meow for all would be .

I believe I was the first to use TIAL on a 996tt (that and $2.00 will buy me a cup of coffee) and have also used Garrett's from their 25's thru 40's. Both products have there applications. To my knowledge Todd Knighten was the first to introduce us to Garrett's to the 996tt with Wilbur's car. As for EVO, Todd Z and I have had our disagreements but I use many of his products (he also has my respect) where I believe he has the best product. I can't recall any Vivid Racing parts utilized in KA, but then again I believe KA has been around a tad bit longer than VR and maybe you do have some products I could be interested in. However, knocking others really turns any interest I could have off. I don't knock anyone unless the guy is a crook. I just believe people who sell products or services and degrade others make themselves look bad. It looks much better when your customers beat your drum for you instead of having to do it yourself. If a company does someone a bad turn or has a bad product, we all usually hear about it from that person, not his competitor.

 

Hey Chad,don't see ya around here much anymore,how's the car coming along?

 

Sounds like a turbo seal to me; turbo might need rebuilding.
