HELP! I need an expert(s) on Ecotec 16V motors - 1.8 and 2.0
I need to tap your knowledge of Ecotec motors.
I've had plenty of dealing with the red-top 16V, but not the Ecotec.
I've bought a Mk.3 Astra Sport with the 1.8 16V motor. Unfortunately it has a hole in the block !
What I am trying to find out is whether the 2.0 16V Ecotec is a direct replacement for the 1.8.
I imagine it will physically fit in place no problem, it's stuff like knock sensors, crank sensors, airflow meter, ECU etc. that concerns me.
Can you help ? Even better, has anyone done this swap ?
Looking at EPC:
ECU's are different part numbers.
The knock sensor is the same on all the Ecotec's in the Astra.
The crank speed sensor is the same (although varies according to engine number)
The airflow meters are the same.
The lambda sensor is the same up to about N reg then changes on the 2.0
I would guess the ECU is different because of different fueling requirements. The 2.0 should use more than the 1.8 by rights.
