This is a great question.
Basically nothing but the turbo itself and possibly the EBC or boost conroller will fit.
The angle of the throttle bodies is different... the airbox or mini-intercooler would need to be changed.
The mount and oil tank will be different as the chassis mounts and bulkhead fitment is different. The same goes for the tunnel dump exhaust and muffler if equipped.
The length of the fender should be ok so I guess the air filter would be OK.
The exhaust pipe is radically different... Just like with your kit, welding the new turbo tail-piece to the stock Pro Pipe would be necessary.
The charge tubes need to fit around the over-structure, so that too would not cross over to the new chassis.
Lastly... the new motor is a CFi 2... so a different controller "Boondocker Box" would be needed... The 2 injectors might not support fuel needs of higher boost.. so additional injector adapters or throttle bodies might be in order.
The new ECU and fuel rail is completely different... so the turbo companies are starting from ground zero here.. they have their work cut out for them this summer!!
