Brother u have many options starting from cheapest to most expensive.
Buy 2NZFE 1.3L of local XLI with auto transmission and ECU of Se-Saloon or any JDM Corolla.
1NZ-FE 1.5L which came in same model X-Corolla.
3ZZ-FE 1.6L of local SE-Saloon.
1ZZ-FE 1.8L of local Altis 2005
1ZR-FE 1.6L dual-VVTi of 2011 shape local Altis.
1ND 1.4L D4D Diesel
3CE 2.2L D4D diesel.
All are bolt on swaps.
Non bolt on swaps are 5A-FE 1.5L and 2C-III 2.0L Diesel with old Indus Auto Tranny and ECU little bit cheaper.
2NZ-FE is most economical and 1ZR-FE is most punchy.
Rough estimate of 75K for 2NZ-FE and 150K for 1ZR-FE with exchange of your engine.
Diesels are not recommended for high maintenance here.
