My dad had a number of occupations during his working years, including being a journeyman machinist and toolmaker, but before he retired he drove trucks for Werner Enterprises (long-haul and team driver) for a few years during the late 1980’s and early 1990’s.
At any rate, welcome to the forum.
The records seem to show that the HA-40 engine is a copy of the DB601.
And after some research and having some of these engines.I have concluded the Ha-40 is a copy of the DB605.
The Atsuta32 is a copy of the DB801.
The Kawasaki HA-40 is not the same as Atsuta32.
The HA-40 is direct injected and has an extended reduction box.Army
The Atsuta32 Is port injected and has the shorter reduction box.Navy
I have yet to find out if any of the parts are interchangeable.
As the Atsuta has superior Metallurgy in it’s harder crankshaft.
Here are examples of nice Tony color fotos

Hello, all the pictures are very interesting, congratulations. This pictures, will help me because Im builting a Ki 61 fighter plane. Unfortunately its very dificult to find pictures in the internet of IJN planes. Keep the good working
Hello, congratulations for the pictures and photos of the planes. Right now it`s very difficult to find this kind of material at internet; all the websites just talk about the Luftwaffe, R.A.F and US airforce. They forgot the IJN airforce, the japs had very interesting planes like the Ki 61,Ki 100 and of course the legendary Mitsubishi A6M Zero.
Howdy all,
Just happened on the site searching for info on WW II Japanese aircraft. I recently returned from Papua New Guinea and while there, was guided to a little know crash site of a Japanese fighter plane. I would like to identify it if possible from my frequently faulty memory. Anyone care to help?? Give a shout if so, and I will provide what info I have. Regards to all.
Ki 61 as the Ki 100 III B tho.
KI-100. Had alot better engine. But still, like 'em all, they were firetraps.

Main reason for continued production was that the Ki43 was relatively simple to manufacture.
It was obsolescent, but could be made in reasonably large numbers, at reasonable pace of manufacture.
Plainly, that over-ruled the disadvantages of weak armament.
As a matter of preference, for the poll, I’m evenly divided between the Ki100-II and the Ki84-II.
Regards, Uyraell.
True, but by then we would have been well into the first generation of jet fighters.

Sorry to be superficial, but I had to go “Dragon Slayer” because that is the coolest name I’ve ever heard for a fighter, and it sounds like you mean business!!
Now…I’ll read through the posts and see which of those actually gave me the best chance of not being blown to pieces!
I have to go with the Frank even though the Ki 100 beats it according to the Akeno tests due to climbing turn performance in the air (not on paper). The speed advantage changes hands from level flight to dive due to stability of the Ki 100:
Frank max 392 mph, terminal dive 497 mph vs Tony 100 max 366 mph, dive 528 mph!
What was the P-51 dive redline, 495 for the D and 505 for the H (I know it could do much faster if it had to)?
I know the Tony covers both the Ki 61 and 100.
The Ki 61-I had a great start but ended up at or near the bottom of the win-loss ratio for the Japanese fighters. The Ki 100 was about even, like the N1K2-J (the 2 best).
Then comes the J2M3 at 1-3 ratio.
The Ki 84 is about a 1-6 ratio. That’s 1 kill for 6 Franks lost, but still way above average.
Amazingly, the Ki 43 claims over half the kills by all Japanese fighters!
I wonder how well that one stands up to postwar verification.
The A6M Zero was average at 13-1. Still about twice as good as the Tony.
(I’m writing this from memory so I say ‘about’)
The reason I say the Frank out of the choices given, is it’s resemblance to the Ki 43.
When McGuire went down the difference between the Ki 43 and Ki 84 was not appreciated by US pilots yet. They thought they were still fighting the same Oscar.
It was really a second Nakajima, a Frank in the last part of the combat. A cannon shell from the Ki 84 was found in the P-38L wreckage. The Oscar didn’t carry that caliber then. Confusion like this works in favor of the Frank.
For me this remains the KI84 Hayabusa, as are arms and performance made him the equal of the best Allied fighters, only its production was low. For story, Americans regained a KI84 in perfect condition and sent aus United States for testing, to their great surprise the plane with an essence of quality and a very good oil displayed a higher power engine 400CV to that of devices used by the Japanese.
Friendly Fred
I didn’t mean to confuse you too. I believe you meant the Hayate, not Hayabusa.
Still, you know more languages than I do. Your English is better than my French.

Yes my dear Ron, sorry for this mistake, and excuse but my english is wrong and generaly I translate by Google.
