yep - its a unicorn.
I found 2 of them in Shershah once - the shopkeeper was literally begging me to buy them as no-one had bought them in 4 years. My aunt (paternal) had a car that had this engine as factory install - it was badged as Honda Vigor 2.0 Si.
I bought the engine for Rs 26,000/- to replace the one in her car, it had crank noise after the driver oil change was done with "ghora marka tael"
the other one had a cracked valve cover and missing dizzy and cam sensor, was a bit blackish inside so I left it there. I did buy both PH3 ECU's he had for Rs 500/piece (stock Accord B20A ECU)
sold one ECU to a guy in USA - he was a 3g fanatic.
