Assuming you would like an in-depth answer to this question:
Yes, you can turbo a stock 4AGE. However, there are a few things you need to take into consideration before doing so. First, the 4AGE is a naturally aspirated engine, meaning it relies on atmospheric pressure to draw air into the cylinders. By adding a turbocharger, you are increasing the amount of air that is forced into the engine, which can lead to problems if not done properly. Second, the 4AGE is a relatively old engine design and as such does not have some of the modern features that newer engines have that make them more resistant to added stress from forced induction. This means that if you do decide to turbo your 4AGE, you will need to be extra careful about monitoring engine parameters and making sure everything is running smoothly. Finally, because the 4AGE is not originally designed for use with a turbocharger, there may be some compatibility issues that arise when trying to install one onto the engine. Overall, it is possible to turbo a stock 4AGE but it requires extra care and attention to detail in order to do so successfully.
