I spoke to a representative at roock racing and they also have engine programs. there are a few to choose from, cheapest being a modded S engine w about 300hp, up to a modded 996 engine yeilding over 500hp. Prices range between 8k and 25k, not bad for what you get. Installation is about a months time for all the necessary adjustments and fine tuning.
