as much as i've been able to find out after hours of research is that its a chinese engine designated ca4ga1, but not indegnious , it is actually a reverse engineered version of a toyota engine, so we should be happy but its not the very common 2nz-fe (xli/gli) , its a mix of the 2sz-fe and the 2nz-fe, so we can ask local vendors to try and fix these without much worry ,for repair(methods and parts) first 2nz-fe should be okay but if not then look for 2sz-fe(vitz 2k06-11?) nd that should work otherwise faw dealership , that should be last resort, meanwhile i personally think it looks more like the 2sz-fe (vitz gen2 i think) engine. reference pic, all else we can do is to pray that it is indeed true , only time will tell
