    GR Yaris (Gen 2) GR Yaris GEN 2 - Heat soak issues

    someone with access to ecu could see what is happening. You could always visit at Toyota service center and they can check if everything has been running smoothly. I think ecu stores certain data (at least they were able to track my power steering issues even though it gave no fault code as such...

    GR Yaris (Gen 2) GR Yaris GEN 2 - Heat soak issues

    Never had such issues on track, and don't have any MAF cooling. I'd say the issue is something else. what fuel do you use? I am typically bonnet open on pits after track sessions just to get rid of excess heat.

    GR Yaris Coolant Temperatures Too High Despite Upgraded Cooling System

    Your setup is different but I never get coolant temps above 92'C on track. Oils go to 105-110'C (not accurate as I have only standard very vague oil temp gauge), but Coolant temps stay usually btw 82-88'C, even on hot day (for us its 25-30'C). I would check the thermostat and air in the system...

    GR Yaris Intercooler cooler pipes

    No spesific experience, but requires likely custom pipes if you want to try 3''. I had already fitment issues with Weldspeed intake and Wagner tuning hard lines that are 60mm, so pipe after IC needed to be modified. As you're building with nice bits maybe an educated shop could help you out...

    GR Yaris (Gen 2) Reverse Engineering the TG-RR GR Yaris: Part 1 – Engine Bay

    Very cool intel @tonic !! On track I was seeing brittles of water in medium right hander - need to check if that was a exessive coolant. :D Lots of same stuff added in own build.

    GR Yaris SRD Tuning engine disassembly and assembly videos

    Nice detail on engine mechs in SRD tuning engine video. Didn't know the story with vacuum pump before. I had a thought before of doing this some point on my own but now after seeing the detail what is needed maybe leave it to mechs.
