I remember seeing a lot of automatic gearboxes coupled to suzui G10 engines in Karachi shershah market, they were very very cheap too as no one bought them, if you negotiated good enough you could buy them at scrap weight price.
The problematic part is the TCU and wiring. The TCU was almost 100% missing from those shops - but you could hunt one from the dashboard scrap shops - its bolted to the dashboard upper pad support behind the glovebox.
In a project I did - I had to purchase about 2 dozen cultus dashboards, I removed about 6 or 8 TCUs from them and returned them to the shopkeeper. They thought it was part of the A/C - I told them its the TCU. They said - yeh kon khareeda ga? automatic cultus yahan nahi chaltee.
to be honest - that autobox is daft and clumsy and is direct drive - the 5 spd manual is far better.
