There's nothing worse than blowing a turbo, having oil spray everywhere or worst case scenario... having chunks of metal get sucked into the block. That could cause the engine some real damage.
To keep your turbo safe you want to run a spring operated wastegate on the exhaust side of the turbo to alleviate all the pressure of that forced induction goodness.
A blow of valve on the intake side of the turbo is also a pretty smart idea to make sure the turbo stays nice and healthy while you're shredding her sideways around the open private roads.
Might be an idea to go all the way and get a nicely sized intercooler while you're at it. Can't be too big or you'll have significant turbo lag and it can't be too small or you'll have inadequate space for doing what it needs to do.
Plus... front mount intercoolers truly look beautiful sitting beneath the ridges and bumper lines that subtly reveal the look of stealth turbocharged performance... and then you hear the turbo spool followed by a "WHAAAAAAPSSHHHHH" or "TSUUUUUTSUUUUUTUUUU" to truly energize the atmosphere with engineering excellence!
