You get more power and torque with less effort from a stroker kit. ie you can run less boost to make the same power or the same boost to make more power.
The kits are all made by reputable companies so there's no reason why it shouldn't be as reliable as the Nissan kit as long as it's put together properly.
You could do nothing to the head if you wanted, it would still work. If you want tho you could get the head ported and fit wilder cams. They should work be abit more friendly nearer idle with the stroker kit than the standard capacity as the engine is sucking more air in.
You could stick with the standard turbo, but it would be a waste not to go at least abit bigger and make use of the reduced lag the extra capacity will give you.
