yeah you're going to want to at the very least upgrade your complete exhaust system (downpipes and cat back). intercoolers aren't necessary but they're recommended. the ecu upgrade would be a good purchase because otherwise your car won't register the extra fuel to inject for the bigger turbos to use. speaking of fuel, awe sells a fueling kit that will give your car a big handful of steroids. i'm getting the ko4 upgrade right now. and in mid-june, i believe i'm going to buy that fueling kit, new dv's, and a new bipipe from apr. i can't wait to finish my car, it's going to be zoomin'!!

 

porsche 911 twin turbo and stop fooling round, if you want power then buy it
