Jb4 or Jb+ is an excellent way to add power. It could decrease the longetivety of the turbos, and probably will. Wastage's will develop rattle and oil seals will go faster. As far as engine there should be no problems. You will need to replace spark plugs and coil packs more often, but thats wear and tear. Good luck.
