What would be the amount of time and how hard would it be to install a turbo?
There are a few diffrent turbo kits out there for our MP5, are there ones better than others?
What else should be changed after installing the turbo to the car? Should there be better brakes, diffrent fluids, ect?

 

There's no way I'd trust a stock fs-de bottom end with 14psi...maybe a B16, but not a Fs-de...

 

It only took two separate days to get my buds turbo all set up. Day one was for getting the electrical and fuel pump set up. Day two was the meat and potatoes of the job.
I haven't installed a Turbo in a P5 yet. I would think that you would still need to get a bigger fuel pump, upgrade your exhaust, boost and A/F gauges if your kit doesn't come with them, and you need some way to have a fitting welded onto your oil pan for the oil return. I dunno how bad in need of a brake upgrade you would need but, seeing as the car would have over 200hp, better rotors atleast would be a good idea.
Your car is somewhat new so there shouldn't be a problem taking stuff off due to rust or anything . So the job is not HARD. Its just really involved. Just follow instructions and do research and you should be ok.

 

I would be weary of that too.
