    Great quality for the price, installed and running well so far. Just wish more details was provided, there’s nothing on the internet giving any details, for example it says “Upgraded turbine shaft and bearings” but no actual details anywhere. Turbo was packaged really well, low key was hoping for a CTS Turbo sticker but wasn’t lucky, haha. I’m currently running CTS intake,CTS intercooler,CTS inlet pipe and CTS turbo!! all in all Thank you CTS Turbo! Proud to have you here in Canada!
