Just wondering who has done a 5sgte conversion here in Vic and what was required for a roadworthy? I've looked at the vicroads documentation, and it seems a bit dubious, because it is a hybrid engine, although it could be interpreted as an engine that was available in this car. Would it need to pass engineers testing or could I get away with a simple trip to get it over the pits?

Currently my car is out of rego so I don't want to have too many unexpected costs or dramas getting it roadworthy again

Thanks

Change of engine


1. Replacement engine is identical to the original engine, or is an option allowed by the manufacturer for the same model vehicle 
The optional engine must be offered in Australia by the vehicle manufacturer as an option for that vehicle (or certified variants). The change of engine may be recorded by VicRoads provided that the registered operator or a motor mechanic, or dealer in that make of vehicle or an Automotive Engineer signs a declaration certifying the engine is optional for the vehicle model, and that all modifications made by the manufacturer for the same vehicle model with that optional engine have been completed. 

You will need to attend a VicRoads Customer Service Centre to have the vehicle's engine inspected to confirm the new engine details. No appointment is required. You will also need to complete a Change of Vehicle Description form.


2. Replacement engine is not of a type offered by the vehicle manufacturer as an option for that vehicle or where alterations, or changes to the vehicle's frame or structure are made, and/or specially fabricated supports or structures are used 
You will need to attend a VicRoads Customer Service Centre for an inspection of the vehicle to confirm the new engine details. You will also need to complete a Change of Vehicle Description form and provide VicRoads with:

• a VASS Approval Certificate from a VicRoads Vehicle Assessment Signatory
• an original receipt for the purchase of the engine as proof of ownership of the engine

3. Replacement engine is not of a type and/or make offered by the vehicle manufacturer as an option for that vehicle, but is equivalent in general configuration, power, mass, and emissions standard to that of the original or an optional engine for the vehicle model and can be installed without any structural alterations.
The change of engine may be recorded by VicRoads provided that the registered operator or a motor mechanic, or dealer in that make of vehicle or an Automotive Engineer signs a declaration certifying that all modifications made by the manufacturer for the same vehicle model with that engine, have been completed.
A Change of Vehicle Description form must be completed providing new engine details. An inspection to confirm engine details is also required unless a Certificate of Roadworthiness or VASS Approval Certificate including the new engine number is provided (only for a currently registered Victorian vehicle). An original receipt for the purchase of the engine must be provided as proof of ownership of the engine.  
When a VASS Approval Certificate has been supplied for a replacement engine, then an equivalent replacement engine can be fitted without another VASS Approval Certificate being presented (eg 350 c.i. V8 engine replaced with 350 c.i. V8 engine).

After reading it again I guess a 5sgte would fall under the category 3. So perhaps I'm worried about nothing, and would not need an engineers certificate but just a roadworthy inspection
 

How would anyone know that it is a 5S block? The block looks incredibly similar to a 3S. Only someone that knows these cars very well would be able to pick the difference when installed in a car.

Because the engine number starts with 5S..  Unfortunately the engine number is on the block, if it was on the cylinder head you'd be using the same engine number :D

I changed many engines in many cars and never bothered to get the number changed officially. It's never been a problem.

It may only be a problem with insurance incase of an accident

Its only a 200ml increase in capacity isn't it?

Thats what concerns the powers that be, a 200ml increase would be laughed at/disregarded in terms of power increase I'd imagine. Its benefits of strength just appear to improve on the weakness of the previous block.

Not updating the block number may only be a drama for car id when transferring ownership.

What I reckon anyway.
