sad update.

Engine blown.

Ill try describe scenario to stop onslaught of questions.
Car wasn't happy on new setup for starters. was getting occasional CEL's after changing turbo/inj/tune.. OBD was saying it was saying it was having problems with the solenoid (stock). i was recommended messing with the restrictor pill either crushing or drilling but the fact he was not sure what way to go with it i didnt want to mess with it. and damned if i could find it in the lines! so we bypassed the solenoid and ran it off wastegate until i sorted a solenoid or boost controller. car has been running like this for a fair while now and hasnt missed a beat. mechanically the car still seemed as healthy as the day i got it.
car cruise, 200k's round. week old oil, same stuff for years. levels checked obviously.. had mate and club president in the car with me.. i had a few too many beers and let him drive home. hes pulled 6th back to 3rd at a considerable speed by mistake. motor revved pretty wild.. i shrugged we continued. about 5 mins later someone has blown a hose of so we pulled over, is when i noticed the death knock. drove short distance and it was getting worse so we pulled over and had a mate come trailer it. mate offered to pay repairs but just settled on some cash towards repairs as i wasnt happy with im forking it all. car off to perth asap to be pulled apart, diagnosed and take it from there.
Probably gonna give it a bit of a tickle while its open too if my budget allows.
regardless im fixing it and going to make it better than before.
