The std DHLA dellorto is not suitable, for blow through turbo.
You can get specific DHLA's that are though, the main difference is not so much the seal it is the float, this being made of brass rather than plastic which could crush under pressure, though the seal is a different sort too.
Most carbs can be used easy enough with suck through though, depending on what you want to do, and this has several advantages over blow through, the fuel helps to cool the charge air temp, and the impeller breaks up the fuel droplets so it mixes better.
