What is difference between regular exhaust manifold and turbo manifold?

If you’ve ever looked at a regular manifold and a turbo manifold, you’ll notice that the regular manifold is pretty straight-forward, while the turbo manifold looks a little crazier. That’s to accommodate the turbo. While you could hypothetically weld on a flange, you would be dealing with space and routing the intake side a bunch of crazy ways. So you’d probably be better off getting a proper turbo manifold. Plus, turbo manifolds (aftermarket ones at least) have bigger tubes to allow more air flow.

Turbos harvests energy from exhaust gazes, other than kinetical energy coming from the piston pushing out gazes, creating pressure in the exhaust manifold, this pressure creates heat that expands the gazes driving the impellar harder. Basically, real turbo manifolds are very compact to address this so that the heat is not lost. But yes it is possibly with a N/A manifold, its just not as efficient. I am not a turbo engineer, this is just my understanding of it. Perphaps its somewhat right and can somewhat help you lol

Everything that has been said here, but with the addition that the manifold needs to support the weight of the turbo as well. and as good a design as some manifolds might be, a stock one might not be able to do that.

you are better of getting/making a completely new manifold
also if you are asking this a kinda feel like you know too little about turbo( engines/setup)s to be doing this stuff
I’m sorry but I would educated myself on (custom) turbo setups/conversions a bit more before going on with whatever you are doing
