How bad is the JB4 for the engine? What are possible long term effects if any?

More power = more wear. But honestly the N54 holds up like a champ compared to a lot of other motors.

Your turbos might wear out faster if are pushing more boost and it will put some strain on your HPFP.

I haven't really heard of many people having true engine problems such as pistons or anything though.

Really for all the shit people throw at this motor, there have been very few problems. The JB4 is excellent, i run it my self but like Vlaze said the real possible harm of something like the JB4 is just putting more strain on the powertrain.
