Hello, I just bought a used 2005 scion tC, Everything seems to be in working order other then the fact i had to replace the clutch master cylinder. The car is in excellent condition. I am new to scions in general and not only that the car came with a full turbonetics turbo kit and it looks like it professionally installed and also has a unichip. I would like to get some input from more experienced people in tC's that are turbocharged and what are some things i should be looking out for to keep the turbo in good working order without running into any major problems. Its late right now so i wont be able to get any pictures up until tomorrow. So if anyone could help me out with some do's and dont's it would be much appreciated.

General info

2005 Scion tC
73000 miles
Engine light is on I will try and get a code asap it has something to do with o2 after cat
Stage 2 clutch
300ish hp

I would also like to know what type of Engine oil i need to be putting in it and about how much extra for the turbo. Also what i should be doing with the coolant considering the turbo has 2 coolant lines. Please bare with me as i am new to these engines and very new to maintaining turbochargers.

 

if the car has no cats, than the engine light is most likley on because of a catalist eficiany monitor code being set. your second o2 sensor shouldnt ever switch and now that there is no cat its prolly switching. other than that i would run synthetic oil. there are many brands just pick one you like

 

I dont believe the cats are out. The car is still running stock exhaust and runs actually very quiet. My friend was telling me to get a wide band o2 sensor and it should fix the issue.

Also sometimes the engine will idle a little weird not sure what that could be or maybe its just normal.

 

Stock exhaust on a turbo'd car? Ohf! P.s. there is an entire section dedicated to forced induction, check it out.

 

Coming from a previous owner of this turbo kit, No extra oil is needed, just run whatever synthetic you desire. Nothing extra with the coolant needs to be done. Just make sure you have it properly topped off. The engine light for the secondary O2 will always be on if you don't run crazy concoctions of anti-foulers and weird stuff to trick it into seeing cleaner air. A wideband O2 would not fix this issue, your friend has no clue. Other than that, get an AEM UEGO Wideband kit so you can monitor your AFR's to ensure proper tuning. Best of luck.
