all 6-speed corolla sportivo or similar models are running on 2zzge, dunno here lar, but US's sportivo has a slightly detuned 2zzge.
TRD's supercharger for ZZ class engine is marketed to be bolt on 1zzfe instead of 2zzge, i dunno if it can be used on 2zzge or not, but if use on 1zzfe, it raise the torque up to the level same with 2zzge only.
cost, found at superchargersonline.com, convert from usdollar, should be no less than 10k ringgit.
-edit-
found on same site again, blitz's kit for 1zzfe/2zzge on a celica cost twice the price of TRD, but they look cooler lar.. with blitz i/c. dunno if it fit corolla or not.
