Pre turbo is not a very good idea.
Good: It's a good way to use a cheap low pressure pump and a simple anti-siphon check valve.
Bad: The main problem is you are using the turbo to atomize the water. This is VERY hard on the turbo. It's just like sandblasting the turbo blades, they will dull down and wear out. Using WI you are likely to start injecting at/near full boost. The turbo is spinning at 100,000rpm+ by this time and the effect of a stream of dense, cold water into the compressor is intese stress on the blades and shaft.
Go for the quality install and get a good 100+psi pump, solonoid valve, and atomizer then install it post-intercooler.
