It was originally a 2Lt, and is now a 1kz, fully loaded variant. Other than that, it's pretty much stock.
And no, I didn't convert it, I purchased it this way, got all the belts and oils changed 2 years back. Sparingly used it, till I ran out of space for it, then parked it at my uncle's house, there it's used just enough so that nothing goes wrong with it.
