That liaquatabad shop is Amin Bandhani who is a scrapper from Shershah, He may have the engine but dont always fall for what these guys say, because the following is what I saw in person.
This moron installed a bastardised 2L and 2C fuel injection pump on a 2LTE and told the "new owner" that everything is good and turbo is working because its compressor wheel was spinning. This is major level of cheating as the pump he installed did not have the fuel enrichment device on top of it. That engine will never make boost or increase torque as the fuel is missing.
I have seen him do the same on 1KZ, Mitsi 4d56 etc etc.
So as always - whatever scrapper you choose to buy from, do not take their word 100%.-
Diesel compression tester is expensive but very easy to use, you need to remove the injectors and screw it in, bolt the starter to the block and use a battery to spin the engine over. Check where the tester stops.
