Hey all

Recently my brother has bought a R31 station wagon.

Started its life as a non turbo, but has been converted on the same non turbo block to a turbo.

does it have to go through regency now?

Can i just tell motor reg its now a turbo?

Will the insurance company be ok with it being a turbo?

cheers

I was surprised about a year ago when I found that SA Transport webpage does now list guidelines on modifications, and what is and isn't illegal. For this particular change - adding a turbocharger:

https://www.sa.gov.au/topics/transport-travel-and-motoring/motoring/vehicles-and-registration/vehicle-standards-and-modifications/aftermarket-components

Turbo-charging/supercharging petrol engine vehicles

Turbo-charging or supercharging an engine increases the power of the engine and may increase the exhaust emissions, fuel consumption and reduce the service life of the engine.

Passenger cars and passenger car derivatives (car type utilities and panel vans) manufactured prior to 1 July 1976 and fitted with petrol engines can be fitted with a turbocharger or supercharger to the original manufacturer's engine without DPTI approval.

For cars manufactured on or after 1 July 1976 the fitting of a turbocharger or supercharger requires one of the following:

  • the vehicle is fitted with a Second Manufacturer's plate to demonstrate compliance with all Australian Design Rules
  • the vehicle to pass an IM240 emissions test
  • the converted vehicle is identical to the production turbo/supercharged vehicle.

In all cases a statement of requirements is required and the vehicle must pass a roadworthiness inspection.

Certification from a professional engineer may also be required. See list of qualified engineers recognised by DPTI - MR426 Chartered Professional Engineers 409.4 KB .

I'd imagine these sorts of engineering changes would include checking over whether the brakes are adequate, any changes to the fueling system are within specifications, that adequate exhaust & emissions systems are in-place, etc.

I thought the general consensus with these cars was to keep N/A's that way, as they're then still P-plate legal, and those are in-demand. Also - the cost, engineering, legalities, and extra police attention of a converted car (and they're probably worth less than a factory turbo, or plain N/A) making it generally better to just buy the turbo car instead.

Yes, i thought so too. But people still want to do it for some reason..

I guess for them its not about the money or the legalities its about the project, and they can then complain about the whole process and unwanted attention.

Only makes sense if u have a wreck that u got for fu*k all with all the required parts to raid. Still lots of work though. I still wouldn't do but each to their own.

    • I've searched fairly extensively among Japanese websites but found nothing really like those skirts in your photo. The closest I got was Origin Labo side skirts however they look more 'complete' in that they have a finishing piece or tab at the rear of the skirt so it blends into the bodywork, unlike the one in your pic. For that reason I'd say the skirts in your pic could be adapted from another car and they didn't include that tab piece, or those skirts aren't copied from an existing skirt but an original design. Sorry I can't help out in regard to ID'ing/sourcing them
    • Wonder if JB Weld sponsored the event lol
    • There's a big difference between a car built with millions of dollars in R&D, and someone like yourself taking a normal sporty road car, and making it 5 times more powerful. At the same time, get a modern sports car, and you can turn them up towards the 1000hp mark a lot easier too. Also, give that Lambo another 20 odd runs, and chances are it too may break something.
    • There isn’t really a cheap upgrade here. If someone made a decent, bolt in 6 speed that holds some grunt, it would do very well. The 5 speeds suck. You can put a - OSG 5 speed gear set into it. Ratios are tall so it zaps the “zing” out of it. Had one, busted it. - PPG 5 speed gear set synchro or dog’s. Ratios are even taller. - An overpriced Getrag. Nice to drive, expensive to source now. - A sequential of some sort. Expensive, very expensive. How many times do you pop a 5 speed before you throw the toys out of the cot?  
    • Yes, fair call. I don't have any special love for super/hyper cars but it was impressive to watch the Lambo line up against successive skylines without any problem at all.
