In some areas it may be easier but you'll have twice the turbo oil feed and return lines, a Y pipe for the intake/intercooler that will merge the compressor pipes, exhaust plumbing for both turbos discharge, two turbo mounts that bolt to the block, two wastegates and the boost lines for those, two intake filters and cold air intake pipes for them, all the added exhaust flex couplings if you need them.
The only real thing that makes it simpler is not having to do a crossover pipe and merger for a single turbo and the passenger side header is a pain in general. I liked a single setup on fabo where he put the turbo right in front of the water pump and had the compressor face the intake. Looked pretty slick. Lots of different styles of doing things and your ride is a blank canvas. Browse around a lot and get the best game plan for your time and money.
My single turbo won't beat twins but I build boost around 2500 rpm in a 318 with a 62-1 turbonetics .84 a/r at high altitude.
If you're set on it, go for it, there's lots of folks here to help you out.
