Not looking good for you man.
Code of Practice for Light Vehicle Modifications found here http://www.tmr.qld.g...sreductions.pdf
Page 31
Section LA
2.3 Schedule B
Original weight (tare) in kg's x .294 (for mono constructed) gives maximum replacement engine size in cubic inches (naturally aspirated)
Tare weight figures for LX Hatch seem to vary between 1209kg and 1213 kg as per
http://www.gmh-toran...ck-tare-weight/
So based on the highest tare weight of 1213kg the max ci naturally aspirated for an LX hatch appears to be 356 ci
Best to speak to TMR and a couple of engineers though. Nothing beats hearing the correct information straight from the horses mouth.

The heaviest Torana is the SL/R A9X Sedan with a tare of 1306 kg.
In theory you should be able to use this figure as it is the heaviest sedan version of the model. Section 2.3.1.4

^ Good Point. As the LX Hatch doesnt appear in Table 3 you might have a bit more room to move.
LS2 - Can you point me to a credible or verified resource that quotes the 1306kg figure please? It will be very handy
Cheers,
T

The L34 is also listed as 1306 kg.
There a lots of discrenpencies in the kerb weight figures that I can not explain. For example there is 45 kg difference between the LX pre-RTS and RTS SL/R 5000.
LH SL/R 5000 is 1236 kg.
LX SL/R 5000 is 1236 kg.
LX RTS SL/R 5000 is 1281 kg.
The WA rego authorities have 1204 kg for the Torana. This appears to the the pre-RTS SL 6 cyl hatchback.

Hi Guys.
Virtually all of my figures come from GM-H literature, the few exceptions are where I've used CAMS homologation paperwork.
I can't explain some of the discrepancies either, some don't make sense, some I believe may be GM-H errors.
A possible reason for the differences in the LX SL/R 5000 figures, would be what is not mentioned. The first batch of LXs were virtually identical to the LH version (so they just publish the same weight). In July 76 ADR27A was introduced, which added quite a few small items. On there own they don't weight much, but if you add all of the small electrical switches, vacuum valves, EGR valves, exhaust vacuum flaps & extra wiring & plumbing this could add say 10-15 kg. By 1977 they added a larger heavier brake master cylinder (it was cast iron remember) & side intrusion bars in the doors. For the RTS upgrade, the shocks & springs were all slightly thicker & heavier but the heaviest add-on would have been the rear stabiliser bar & fittings. Another 25-30kg easily.
I'm sure all of this could amount to 45 kg. But as you can see, it's not just the result of the RTS.

Thanks guys guess i need to speak to the man that kinda dont like me or the car.
When we talk tare weight of a vehicle dose the ADR take into account new engines ie the light weight billot or alum??
Australia needs to standardise laws.
Anyone know of an exceptional engineer in the Mackay area??????

No it's the weight of the vehicle in its standard form. You can put as much weight, or take as much weight off as you want.

Thanks for the explanation Dr Terry, it makes more sense when you consider the ADR changes around the time of the release of the RTS Torana.
Do you still have access to any official documentation regarding the L34 or A9X weights should a rego authority want more information?

I have Holden original dealership sales documentation that states SL/R5000 @ 1275kgs if you would like me to scan it and send it to you. It should suffice to satisfy an engineer or the DMT in QLD,. We use it here in ACT and are what we base the NCOP engine transpants on. Allows for 6.3L in n LX.

Just safely assume 350 CID is fine, you can stroke it to 383. Or a 400 CID SBC destroked to a 372. Both should be fine.

There are no consulting engineers in Mackay who can approve this mod.
Derek Clapton Automotive will be your best bet! He does the pre-inspection work for a Townsville based consultant.
The D.O.T will give you a printout of all the consulting engineers in the district & the mods [codes] they can approve.

The old rule of thumb for hotrod Torana's is, use the biggest engine that allows the bonnet to close. Less likely to attract attention when you dont need or want it.

G'day guys, don't know why, but i'm having search issues at the moment - so forgive me if there is a better thread to discuss. Anyhow, has there been any recent developments as to the max weight one can [proven] denote for a hatch (interested in Vic laws mainly)? Basically, what's the max CID we've heard of being passed currently? I suppose it come's down to whether the aforemention 1275kg is accepted really? Thanks for any info/links in advance - Cheers Peter
