To state the obvious you have water in the oil, probably from a blown head gasket and the pistons have detonation marks.

Looking at the carbon deposits on the pistons the detonation has happened in the past.

I just got the car two months ago and it was misfiring since the start but didn’t really got deep into it, what is the best solution to fix the problem in your opinion?

New engine and proper tune. Sounds like you bought a dud.

Source another engine, that one is going to take a lot of $ to fix.

Try to establish what caused the failure. Check the head for straightness and cracks. If it can be fixed then this is a good time to consider an RB30 build. If you can find a decent RB30 block then just rings, bearings and con rod bolts should see you right.

Cost will depend on what you can do yourself. If you are not keen to build the motor then a running second hand engine will be your best bet.

As a matter of interest do you know what kind of ECU is in the car?

I honestly dont have any background on working on cars...might buy a second hand engine if thats the case

Looks like broken rings? I have a good neo turbo bottom end if interested.
