Alot of ways that work money and fabrication skills play a big part .large long tubes will heat up your engine compartment better but look more intimidating also may help delay the hit of big boost to help hook your car.
4 cylinder engines can benifit from tuned headers designed to keep the pulses even to spool big turbos.
8 cylinders dont have this problem and a simple log manifold keeps the velocity and the heat high to spool you up faster it does not take alot of boost to make you happy and get you hooked.
build what your wallet can aford and move up from there.
sise the turbo right and get a good wastegate and you will be in love also not a bad idea to learn the tuning lesons on a low buck engine first.

You can simply weld a flange on top of one of your manifolds run a crossover from original outlets with some type of slip joint or flex joint to deal with heat expansion.
Also turbo needs a oil supply and a large oil drainback to the pan i have made a plate and used the fuel pump mounting pad for a quick down and dirty path...
add turbo and wastegate and go......

Heres some fun cobbling from years ago.
