People have run the stock turbos up and past 17 PSI. The stock map sensor is limited to 17 (ish) PSI. However, how efficient the turbos are at those higher levels is the problem.

Push? Are you talking boost levels? If so, safe boost levels are defined by many parameters:

* fuel system (Air/Fuel ratio)
* turbo efficiency
* intercooler
* air flow
* driver skill (or lack there of)

What single turbo depends on the type of application (i.e. what type of driving for the car). Also, there is more to adding a single turbo than just buying a single turbo kit. The fuel system needs to be addressed, ECU and it's programming, etc.. It becomes very costly, very quick.

That is based on the number of total posts you have. Not all forums here count towards post count (places like the lounge don't count).
