Ofcourse you could custom build a turbo to fit just about any car. The questions is are you going to do it yourself? Its all about fabrication. If you have the means to do it yourself, well then more power to ya! The materials exist, thats for sure.
But that's where Street Flight comes into play. They've already done the fabrication. Not only that, they've done the required tuning. That's what you are paying for. You may be able to build one yourself, but there is a alot of time involved. You just have to decide whether time/engineering/materials/tuning is worth the money saved.
The only place I see it being a shame here, is the price of that specific kit. I don't mean its now worth it, I only mean that other car owners aren't forced to extract their kidney in a seedy motel bathroom to pay for it.
Any boob can slap a turbo onto a car. Getting it all to work properly, is another story.
I want to stress here, I'm not calling you a boob
and I'm not saying don't do it. If you have the means and brains, and a little cash to buy materials/turbo/fuel tuner, go for it!
