Dear 1.8 1zz-fe is a really good n powerful engine if one can afford the fuel expense it's perfectly alright...I m using 1.6 gli 1 zr-fe with an auto tranny n I m really satisfied with it Allhamdolillah.1.3 2nz-fe gli/xli is slightly underpowered and makes a lot of noise while running and it's rpm remains high...
