VB 2.85 Specs

[Holden6GodsMotor]

Interested to know the specs of the 2.85 (173) and the differences between the VB model and the other 173 motors used in the H series and the Torana.

More pollution gear for a start

Red or Blue?

Different head between the 2...Different carb/exhaust manifold between the 2....


Cranks are different between the 2

Not sure about piston/ring combos....

That's the differences I am aware of between the blue and reds....

Sumps and oil pick ups differ between the H series/Torana/Commodore motors

What are you after specifically?

 

[Smitty]

'Red' motor VB, HZ and LX 173 engines are basically all the same except for the necessary things to fit them to
different model lines. Sump changes, carby cable/link connections, wiring harnesses will be different...

The Red 173
Just after a list of specifications really and what is specifically different.

Much difference in power/torque?
I heard the VB model had less perhaps due to the increased pollution gear.

Basically the stuff @Smitty has mentioned...Yes, they also have added pollution gear

I heard the VB model had less perhaps due to the increased pollution gear

that was a myth ,most of the pollution gear didn't do anything at full throttle . EGR, efe ,vac advance lock outs while cold if manual, (no advance unless in top gear most used to get rid of that bit). As much as I didn't like vac pumps on blue motors when removed their wasn't any extra power.

So does anyone know what the actual power/torque numbers are? I've seen a range of numbers thrown around.

.. the ADRs for pollution didn't change from when HX came out until just before VC was released
