without compression test how someone can 'announce' engine life is over ??
Your Toyota GLI is a PKDM model. Engine overhaul OEM parts are available brand new.
Scrapyards have scrap engines, are there for a reason.
Overhauling 1NZ is piece of cake,.with timely maintenance an overhauled engine can last over 300,000 kms without trouble. changing engine will be high risk and doubtful.
overhauling will be far economical then swapping with scrapyard item.
