Good to know.
Yes of course I knew the risks but I was expecting bottom end problems and not at this power levels.
I will let you know the root cause, I thought maybe someone had similiar issues, but apparently not. I think gasket or head lifting due to assembly low quality of this car, but are all suppositions.
For example on the ej series you can find almost everything online, but to be fair those engines are around since the cars were invented and they are used more in racing applications.
Thanks for the inputs!
