Comparison between the L15A7 engine and the L15Z1 engine
Hi everyone,
I just have a question regarding the above mentioned engine codes.
The GE Honda Fit 1.5 i-VTEC were all fitted with the L15A7 engines, while some GK5 Honda Fits in certain countries were fitted with the L15Z1 engines.
The power specs are exactly the same, Hp and Torque exactly the same, they are also both i-VTEC engines.
L15A7
SOHC 16 valve i-VTEC
Displacement: 1,496 cc
Bore x Stroke: 73.0 mm × 89.4 mm (2.87 in × 3.52 in)
Compression Ratio: 10.4 : 1
Power: 88 kW (118 hp) / 6,600 rpm
Torque: 145 N⋅m (107 lb⋅ft) / 4,800 rpm
L15Z1 i-VTEC
SOHC 16 valve i-VTEC
Displacement: 1497 cc
Bore x Stroke: 73.0 mm × 89.4 mm (2.87 in × 3.52 in)
Compression Ratio: 10.3 : 1
Power: 88 kW (120 PS; 118 hp) / 6,600 rpm
Torque: 145 N⋅m (107 lb⋅ft) / 4,600 rpm
The only noticeable difference that I can see is that the L15A7 has a part aluminum, part plastic intake manifold whereas the L15Z1 has a full plastic manifold.
Can anyone please tell me if the head cylinder designs are exactly the same?
The reason for asking is because there are manufacturers that make camshafts for the L15A7 but they never heard of the L15Z1 engine yet, or had a chance to do research and development.
I have the L15Z1 variant in my car and I am desperately looking for solutions to gain a bit more power by port and polishing the head and adding a performance camshaft.
As far as I know, ALL L15 engine blocks and internals are exactly the same.
Thanking you all in advance, please help me make a decent build, and yes, I will be boosting my car.

No, I sold the car and bought a 2012 Toyota GT-86.
I might get back in the Fit game soon as there is one available in my country with a K swap. The only issue is that the guy's price is too high and matches the price of decent FN2 examples.
