Cowl and engine assembly.
Cowling
A penny made a perfect mask for when painting the cowl
Modestly weathered Sakae engine
Assembly
Soon to be mounted on the wing.
Exhaust pipes. MM Burnt Iron, what a cool color for exhaust.
Collector rings.
All exhaust pipes will get a watered down purple ink wash for that spectacular hot metal "blued" look.
By the way the nacelles are four parts each pictured here (not including the collector ring), I was worried, but fit and finish is exceptional.
Collector installed
You have pry it open and it snaps in place. It fits tight and did not use any glue.

You can see here how the three parts of the nacelles come together. I did not bother with finishing off the centers because the engine gets glued directly to the nacelle here.
This is my favorite part of modeling...
... getting the engine assembly together.
I have chosen to do flaps open. The closed flaps make an ideal mask for transitioning from the anti corrosion blue to IJN green.
The demarkation line can be seen here
