engine swap

[ardyrr]

I have just bought a VZ wagon at auction and here is my dilemma ,the is hard to start and when it eventually starts i get a few codes on the scanner ,one is cam angle fault and the other is 02 sensor fault it wont rev past 3500 rpm.When I checked the engine numbers from those on my rego papers i noticed the papers said LEO engine code and the motor in my car said HBA can anyone help me correct this? I can buy another wreck with a complete motor and all electrics but i'm not sure if it can be swapped,thank you Ed.

why change engine, new cam sensor set of O2 sensors should all be good, get codes cleared etc, engine wont rev past 3k while stationary, safety feature,

problem is LEO motor has 4 02 sensors mine has 2 and i already replaced cam sensors and even replaced the connectors but still wont rev when driving and very hard to start.

LE0 is the engine type, not a part of the engine number which indeed contains HBA, it's perfectly fine.
The engine type is also indicated in the VIN.

I think the LE0 had only 2 sensors on the VZ but 4 on the VE.
Just replace them, the code will go away and the car will rev.

My car has 4 02 sensors and the engine number on my papers reads LE00623xxxxx and the motor fitted reads 10HBAH051300XXX also my car was built AUG 06 and the engine was built MAY 05.

Engines will have both LE0 and HBA tags, see http://forums.justcommodores.com.au...6/180601-doreholden-vz-replacement-motor.html

In the end, does yours have 2 or 4 O2 sensors?

there is 4 sensors fitted at the moment but i'm not sure if it is original

Your car being from 2006, it's factory fitted with 4, see https://forums.justcommodores.com.au/threads/o2-sensor-replacement.78806

this is the problem I have The HBA motor has 2 02 sensors and the later has 4 so how do I fix this problem?

This is a rough sketch of what actuators and O2 sensors are fed by underbonnet fuses. May help explain if there is a battery voltage feed problem. The diagram is for the 190 kw engine in my SV6. For somebody to add extra wiring for the rear O2 sensors would be a serious upgrade to wiring and programming of the ECU/BCM etc.
