Surpassing Indonesia is not aa big deal. Currently Indonesia is only around 10% ahead of total GDP of Turkey. This means if Indonesia shows a neutral growth rate the next 2 years, Turkey will already surpass them. If Indonesia shows half of the growth of Turkey's growth, this means Turkey will surpass Indonesia in around 4 years (which I think the scenario will be).
