Sorry Trent..this is wrong... talk from experience please. where we don't have experience we should mention it upfront to the OP in order to allow others with experience to be credible instead of having to discredit each other.

A turbo in these cars is relatively easy. Easy because our W body buddies have done all the work. A Bonneville is a bigger and easier car to work with. Sure there will be some customization.....just like on a W body. Each setup is slightly different and that allows us to do cool stuff.
A plog on the front and rear (rear is for turbo) a Y pipe and a custom downpipe is about all you need to get rolling. Add a front mount air to air intercooler and you need to tune. The cam is pretty straight forward and as you research more, you'll find there are good turbo cam grinds out there. I know a couple guys that put their intercooler together cheap off Ebay and you'd never know.
Largest expenses are the Y pipe and custom downpipe from my understanding.
