From: Bedfordshire UK
The I 153 is, "It’s a tricky plane to fly because it’s not fuel injected. Which means if you do positive g’s in it you stall out the engine." What this means is if you are a bomber and if you have a I 153 behind you all you have too do is go into a dive. If the I 153 follows it would stall and fall out of the sky.
The I 153 would not fall out of the sky, negative G would cause the engine to temporarily falter, as with the early Marks of Spitfire and Hurricane, a 'stall' (causing the aircraft to 'fall out of the sky') is when the wing ceases to provide lift, usually due to low speed, or high G turns, and is a completely different situation.
Apart from some civil prototypes, I doubt that the He111 was faster than the Ju88 and the Ju87 certainly was not.
Wiki :- Ju88
The fifth prototype set a 1,000 km (620 mi) closed-circuit record in March 1939, carrying a 2,000 kg (4,410 lb) payload at a speed of 517 km/h (320 mph). However, by the time Luftwaffe planners had had their own "pet" features added (including dive-bombing), the Ju 88's top speed had dropped to around 450 km/h (280 mph)
All speeds can only be compared for similar altitudes and bomb loads, but the Ju88 was fast enough to be adapted for use as a night fighter, later in the war.
Either way the I 153 would have difficulty in catching the He 111, or Ju 88, unless it had the tactical advantage of greater height, to dive into the attack, which would have its own dangers for the Soviet pilot.
Wiki again :-
Early production I-153s powered by the M25 engine passed State testing during 1939, despite the loss of one aircraft which disintegrated in a 500 km/h (311 mph) dive.
