We sold ours in 2019 and got a crv diesel.
Problem with this civic was the air cond compressor. And fuel economy was just 10 km/l, But the engine and gearbox were fine even at 250k kms. We serviced in at the dealer until 200k kms. The new owner still has it and drives it daily.
Maybe just get a compression test done on your engine first. You can get a bit more hp from a full intake, exhaust and remap. This is if you are on a budget. If not, drop in a k24.
