68 Dart GTE Project

I love this build, and have considered the same swap in my car. The 2JZ is one hell of an engine that I've always wanted to mess with. Power seems decent for a 62mm on pump gas, but I did notice the small intercooler right off the bat. Do you have room for a higher flowing core, and do you plan to push more boost once that is resolved? Could you post the dyno graph?

Also, is your exhaust routed all the way out the back? I'm looking to run a single 4" on my duster, but hadn't considered oval piping; how tight was it?
