Problems of Jimny Xiaoji A 1.6M and 1.8M engines.

First of all, I would like to ask whether these two engines are the same as those installed on Tianyu. What's the difference between domestic and imported? Are there any specific parameters? First of all, I would like to ask whether these two engines are the same as those installed on Tianyu. What's the difference between domestic and imported? Are there any specific parameters? Tianyu can't change directly, and the signal teeth are different. Only Japanese regulations can enlarge the cylinder. Is the original factory upgrade of cylinder liner piston and crankshaft connecting rod a direct cylinder change? Tianyu is M 16A and m18a heliograph1.6s are special machines for fast wings. Since the original engine can be upgraded, the scheme of transplanting the engine is not so attractive, but M 16A and M 18A @20 19.
