1800cc with yamaha tuned head, 190 BHP, with VVTLi tech, but be ready for increased prices, b4 it could be found for 100-130k, now atleast 200k, i think with 2zz, alterations will be required but the engine is light and car is also light so wheel spin will be there, plus it will give the fuel economy of around a prado, plus finding a 2zz is also a process. If i were you, i would go for D17 or 1NZ, 1NZ can be found easily, decent power, and fuel consumption will be as good if everything is sorted out, D17 is also a very balanced motor with VTEC!
