Hello Cartalkers, I have been wondering what might happen if I drive a 2.0L Honda Accord and replaces the engine when it is old with say, a 2.4L Engine.

My friend drives has a 2001 Honda Accord (baby boy) and while he travelled and the valves bent as a result of snapped timing belt. He left the car there and went to the nearest autoparts market and bought another engine, which he didn't know is the 1999 model engine (probably with higher displacement) and after it was installed, he complained of slightly higher fuel consumption.

My questions are:
1. Will the Ecu adjust fuel values for the new engine?
2. Will it affect fuel consumption?

1998 to 2002 Honda Accord had only 2.3L engine, it's not possible to fit a 2.4L KA20A into baby boy like ABC, the 2.4L is different in appearance, more expensive to purchase and an headache for kazeem to fit it correctly into the baby boy.

The 2.0L was available in rear markets like Philippines and new Zealand for the DX model. but American had 2.3 as standard depending on trim would determine output of the 2.3L

Thanks but it is not just about "Baby Boy"

In other cars as well, such as buying a 1.6L engine for a formerly 1.8L engine VW Golf (ECU controlled) for example, will anything change?

Yes let's take golf 3 for example

The engines available are 1.4, 1.6, 1.8, 2.0, 2.5 etc.

if you are changing from higher to lower or vice versal you will need need to change somethings depending on whether you are going higher or lower.

1. Engine seating

2. carburetor to injector

3. gear type, lower engines may have 4speed while higher will have 5 speed the lower speed may not be able to accommodate change in power output hence erratic motion and lift off, vibration during change in gear.

4. ECU may need to be upgraded/changed/remapped.

5. Wire harness to important components.

6 belts and pulley change since pulley teeth May differ and diameter change calls for change in belt circumference.

etc.

Difference goes beyond engine displacement...
There would be difference in nozzle and ignition coil sockets to say the least...
