the intake pipes from Stillen had to be cut by 8cm on the passenger side and 6cm on the driver side. I have not yet verified fitment with the completly stock intake system.
For the strut bar this can NOT be simply re-installed but as I track my car very often I will modify it so there will be a strut bar again. In front of the intake plenum you have some room where a strut bar can be placed, just needs a bit welding
yes, stock throttle bodies have been used they fit the GTR manifold no problem, just need the gaskets from R35 - even the bolts are the same. So does the 370Z intake temp sensor, even the cable connector can be used without soldering longer wires, you just have open the wire channel behind the engine and pull out the cable a bit so it reaches the sensor facing in the opposit direction.
only thing I did was to eliminate the TB water cooling so the engine bay looks cleaner and less pipes are around.
