I recently bought a 91 civic and planning 2 do a b18 swap and turbocharging it.This will be a weekend racer,not to be used daily.There are no problems with the engine swapping,but as I'm new to a turbocharging an engine,I need infos about it,plzzzz..Thx guys..
Do i need to change the internals to run a turbo?

 

Changing internals depends on how much boost you want to run and how aggressive you want to be with it all. You also need to think about what kind of a turbo setup you're going to do. Are you going to get a kit, or are you going to piece it together yourself? Piecing it together can be much more rewarding, yet it can take a bit longer to get it all together and you have to know what you're doing. Plus it is usually cheaper.

Try looking around in here. Plenty of people are running boosted b18's.
