how much HP does the Tigra 1.6L ecotec engine gives?
Here's what I found. 1994 to 2000 X16XEL'1.6 L' 100 hp (74 kW) and 111 lb·ft (150 N m) of torque. X16XE'1.6 L' 106 hp (78 kW) and 111 lb·ft (150 N m) of torque. 2002 1.6 L (1598 cc): TwinPort, 105 hp (77 kW) and 111 lb·ft (150 N m) of torque.
it depends on what corsa you have, if its the 1.3 carburater its worth it to swap the engine because the tigra engine is feul injected but if its the 1.4 the its not worth it because with a litte tngkering and fettling it can make the same power as the latest tigra
