Parallel turbos are not usually used because you need more pressure than a single stage setup will provide. What you want to use is a set of compound turbos, where a larger turbo feeds boost into a smaller turbo for higher boost pressure.

Most folks with twins build their own, but there are off the shelf "kits" (still with some fabrication required).
