You've heard correct dude.. what they actually did to this poor engine, they removed all the oils and the coolants... thats why it boomed in 2 minutes. No big deal.
My idsi city L12a2 has 2 lakh kms and it runs like a horse, 100 kms every single day. This d15y3 had just 90k. Its impossible they would've boomed it in under 2 mins with full oil and coolants.
