Being that the turbos and engine for our 124 are the same as the 500, I was wondering if anyone can point me in the right direction as far as what people are using to increase their boost pressure with these and what pressure people are typically running. I looked through some of the 500 forums but couldn't find anything. I was thinking about running either 15 or 20 psi (provided the stock internals on these engines can take that). Mods would end up being simple. Intake, full 2.5 turbo back exhaust(when it becomes available for the automatic Abarth), upgraded intercooler, EDL, Forge wastegate. I'm just looking to have some spirited fun in the car.
