Performance and Mileage:
For 3 Door it would be fine and will give you better mileage ... but if u want some serious performance then go for 22R-TE.
For 5 Door: From performance point of view 22r (only petrol) works smoothly, and mileage would be 7 km/L. Same as for 1kz, but it would be under power.
The engine assembly will fit without any alteration even a single bolt, and 4X4 transmission system also thanks to Japanese casting.
note: If you are expert on Carburetor only then go for it otherwise i would recommend for 22R-E (With EFI)or 22R-TE (turbocharged EFI)
