Hi All,
I need to remove the extractors that are on my WB van in order to meet club registration requirements. Would I be better off putting on earlier manifolds or stick with the WB type? Would commodore manifolds fit or are they slightly different?
Thanks
Rhys

AFAIK the HX/HZ exhaust manifolds are the same as WB V8. The LH-side one is the same back to mid-73 HQ. The earlier RH-side one has an auto-choke tube in it, but is still interchangeable. There is no advantage to fitting the earlier manifolds other than they are probably more plentiful.
Commodore & Torana V8 manifolds have a different shape.

dont know what state you are in but it seems a bit harsh by the club on the letter of the law there.. going to church makes you no more a christian than standing in a garage makes you a car... www.classicozwreck.com.au |

WA Greg, no performance mods allowed when on the concessional club rego over here. Extractors are classed as performance mods but they weren't fussy about my dual exhaust... which would probably be more of a performance mod than the extractors! Well I got myself a set of WB Statesman manifolds, thanks for the link Adam. They are fairly different to HQ-HZ being that they're much squarer looking and flat on the outer face.

Hi,
I sympthasise with you Rhys I have a August 1973 GTR Torana that I can't club licence because it has Perry extractors.
when you consider that the XU-1 was first fitted with Perry extractors in August 1973 the day after my GTR you think they would let it pass, but no way!
I found that the Blue type Holden manfolds were better flowing than the HQ - Z ones due to their increased size, I used these on my gas HJ Statesman without any problems.
Mike

S.A is pretty tight on Historic reg , it varies club to club to what is acceptable to the officers and their general knowledge of vehicles in their club.
We asked questions about different mods at a Historic Federation meeting and got a couple of strange awnsers, years back I asked about extractors and was told `if it looks like a duck then it must sound like one ` stupid awnser realy, at a more recent meeting I brought that up and the guy said he regrets saying that as people would fit extractors with quiet mufflers.
We discourage people from fitting performance products as it is in the rule book, we do allow period mags as long as they are no bigger overall then 10% to the stock wheels.
There are always grey areas from what is written as they do allow certain cars to have extractors due to stock manifolds always cracking(some valiant models)but they refer to them as `custom tubular manifolds` so it opens a can of worms really !

Yes, it is an area for lively discussion, I'm involved as a club registrar in the NSW HCRS for several car clubs.
In NSW, the rules are that it must be as original as possible, however "period accessories" are allowed. It all comes down to how the clubs read & administer this rule themselves.
The debate is then, when does an accessory become a modification ?
With the extractor query on a WB, the answer (at least in NSW) is cut & dried. They're simply not allowed, as they contravene ADR27A, B & C etc. Technically speaking they weren't legal back in 1980/84 & they are not legal now. Extractors on an LJ GTR are legal but many clubs would not allow them because they are a 'visible performance modification'.
The comment "if it looks like a duck then it must sound like one " almost covers it. To explain that more fully, it all comes down to appearances. The whole idea of 'vintage rego' as it once was, was as a legal permit so they could be driven to charity car shows. So an original genuine 'appearance' was paramount. If the car had a bored-out motor or a different camshaft this would go un-noticed, but if it had 8-inch wheels, lowered suspension or multiple carburettors it was way out of bounds or the spirit of the whole scheme.
The problem with historic rego schemes is that many see it as their right to cheap rego for their old car.
I think with new laws looming on modified cars, it would be a good time to start lobbying for some type of rego along the lines of the NSW 'Street Rod' scheme. In some states both stock & modified cars are allowed in the one scheme. This could be another solution.

The ACT system seems to be the fairest then. They will allow a modified car on club rego as long as the modifications are "period correct" so if you could have bought extractors for your HQ back in 1973 then they are allowed.
Technically if you build a 308 powered LJ then you could get it on historic rego. If you build an EFI powered LJ then sorry no historic rego for you.
Nice, simple and fair.

How much does Historic and/or Street Rod rego cost compared to normal rego?
My HK is on full rego in NSW and it doesn't cost the earth, $558.37 or $10.74 a week all up (rego + green slip). I can't see how historic rego is worth the trouble, I can drive my car wherever and whenever I want and I've got the plates I want on it as well.

In Victoria it is not club rego. It is a club permit. The vehicle is actually unregistered and has no rego sticker. It is a permit to drive the unregistered classic vehicle for club events. In regards to modifications, where is the line? Radial tyres on an EH Holden is a modification? Laminated windscreen? 3.08 ratio diff? Trimatic? Extractors? Electronic distributor? Chrome rocker cover? It is interpreted by the Club signing the permit. Discretion of the club is important. If it is old or rare - Cut it! http://www.ehlimo.com.au/ |

Good point. The cost for HCRS in NSW is around $60 per year including CTP insurance, which is good value especially if you have more than one car on the scheme. Many owners find Historic Rego a bit restrictive, others find it great. That's the beauty of living in a democracy - freedom of choice. BTW $558 is cheap for normal rego, do you live in Sydney or the bush ?

I live on the South Coast of NSW in "Regional Australia", so rego is cheaper and I have my household and comprehensive car insurance policies with Shannons which gives me the lowest green slip price as well.

historic rego in SA gives you 90 days per yeay usage, so unless you have an everyday driver it's well worth it....I never get anywhere close to the 90 days allowed
