DV turbo solution

http://gfb.com.au/tech/tech-articles...stems-solution

A cheap way to boost performance

Apart from reducing the sound of the engine could anyone tell me other draw back of this solution? I have little mechanic knowledge

I now know the cons
Installation process for N20 engine of the 5 series is not simple
The cost is higher than that of the good

I just had mine installed on the n55 literally today. So far so good. Power holds strong with my tune. Will post back with more results as I get more driving time.

I'm still understanding it and need more seat time to better explain. I know it's not a power mod, but it makes the characteristics of the engine different. How power is delivered in the rpm range, shifting, back on throttle and somewhat sound.
