if you want you could get a new manifold...but the internals are different...since a nonturbo motor is at a higher compression, it would be ok if you ran at stock boost, but if you plan to upgrade the boost then ull need to change the internals for lower compression, a motor swap just lets you have a turbo motor that is alrdy setup to handle boost, rather than making the changes yourself...its really up to the person thats modding teh car....turbo kits are good at stock boost, but to let the car handle more power and boost you will eventually have to change the internals to prevent blowing the motor
