There is no definitive answer to that question, it varies with each engineer's interpretation of the "rules". The following table is from the NCOP...

...but the emphasis is on the word "Recommended". There are a few examples just on this forum alone of vehicles that fall way outside of those recommendations, but be prepared for some major chassis, driveline, brake & suspension upgrades to go along with it.

 

I guess you could say the table above could be considered a 'bolt-in' conversion guideline?

Square bodies weigh about 1300 kg according to WA transport last time I checked, so that is 6.5 L (396 cu.in) NA or 3.9 L boosted.

I don't think any SLR or hatches weighed in at 1,300kg. Going by Holden factory specks the heaviest Toranas V8 auto topped out around 1,240kg. My engineer said 383ci aren't legal but 380ci 6.2lt just makes it, but it really depends on the engineer if he recommends chassis and brake mods to satisfy him, it's there licence on the line. Some will sign off and some won't. If you read and do your sums going by the NCAP chart posted above a heap of conversions out there aren't legal.

 

You also have to keep in mind the engine block casting date. If the block date is older than the Torana your trying to fit it to it may not comply with pollution regs. It doesn't matter  what speck the engine is built to or which vehicle it was sourced from the engineer has the right to reject it.

DOT in WA are on a big power trip at the moment and are making up the rules as they go along. They are no longer using the national code of practice (VSB14). They will not pass any LS motor in any Torana.

The pics are from a bloke who was building a 327 EK following the VSB14 guidelines and had it rejected before he could even get it to an engineer. There is NO appeal process either.

I had a lot to do with the introduction of the NCOP in 2006 in ACT.  It is very sad to see that a lot of States are ignoring a very reasonable code of practice.

To the best of my knowledge, Gerry, NSW (along with SA) never officially adopted the NCOP, we're still using the NSW LVCOP, which is even more out-of-date.

Seriously, what a pack of bastards!

 

It sounds like this bloke already had approval (presumably in writing) and he was just asking for a time extension, now he's got nothing? You would think any existing approvals should be grandfathered.

 

I bet he's kicking himself now, should've just laid on a couple of slabs for a heap of lads and had a working bee, get it done in a week, passed and approved under the original approval.

 

Anyway, that's all moot since Stevo is in Victoria.

 

In the end it's all about finding the right engineer and doing whatever it takes to get his or her approval. As an example, have a read of LoHla's build thread:

I've seen some weird and wonderful things happen with club rego too 'south of the border', not sure what the inspection process is at the club level in VIC but that may be another option?

Zagari Engineering in SA,  so I believe took rego to court and one, allowing vehicles to be engineered with big motors and wheel tubs. Have a look at there Facebook page, some pretty amazing cars that are registered.

Yes NSW think of themselves as the only ones who count and make their own rules.  Can be very difficult to deal with and don't like be told what they can and can't do.

ACT has had some doozy arguments with them over the code over the years....

It's all about protecting their a_s if the vehicle is involved in any accident (even minor). My understanding from inside is that there is a strong push within DOT to remove all old cars from the road and clamp down hard on all illegal performance modified cars. The bee under their bonnet has been a new 20yr detailed accident analysis/report.

 

With the strict new car safety laws (getting very advanced) the studies on accidents have indicated that older cars are a big public safety issue. DOT certainly are making things almost impossible even though we have current approval. I have jumped through all the hoops, have crossed our t's and dotted our i's but even the engineer said it's ridiculous that they can change the rules 2yrs into an approved project. No common sense within Welshpool. If they think they can chop and change with the wind they are very wrong. It's stupidity to have to go to court because you followed their agreement, rules, timeline but I guess in most cases people just walk away regardless of the facts.

I had forgotten about your build Cameron. Have you gone through the courts yet or is that still coming? How far along is the Torana?

It has been given over to the lawyers whom are awaiting august date options (I am done talking to DOT) . They have sent our case (spelt it out) to DOT and given them 30 days in a hope we can get some sensible response in an 11th hour bid to avoid the large court costs. Not what I want or need but they have gone rouge and not following the rules. Too much money involved and its a very long project that has stalled so not happy is an understatement.
