PG 3 original engine number = The one you have in it is the only one you know..and thats the one its registered with.
PG 3 replacement engine Kw = 240HP is the commonly accept power output of a red carbed 308 convet that to Kw...a VL black is 122 Kw

PG 4 summary of details
Engine Make & Year: HOLDEN 308 ( you didn't give a year??)
Engine Modifications: N/A (so you aren't modding it now?) if you are you need to specify cam, carb, manifold...anything non STD.
Transmission & Mountings: Ford Topload
Differential: Ford 9�
Vehicle Height: seek clarification here..it may mean height from ground to top of roof.
Front Suspensions: I think they want type...conventional coil spring, macpherson strut ect
Rear Suspension: as above
Chassis: N/A
Steering: N/a
Braking System: 290mm drilled DBA rotors and calipers (Hopper stoppers)
Tyres Front: 245/40/17 (what does NCOP say about tyre this big on this car?)
Wheels Rims Front: 8� wide 17dia
Tyres Rear: 265/40/17
Wheels Rims Rear: 8� wide 17dia
Seating: OEM
Lighting: OEM
Body: fitting of Torana wheel flares, bonnet scoop & rear wing, cutting guards, cutting hole in bonnet (bet you have problems getting the reverse scoop passed)
Exhaust System: Try-Y extractors, twin system dia2.5�
Other:
Provide further details of modifications under the relevant headings overpage � answer all questions or write �not applicable�.

Pg 5

Engine �
will the engine be modified = as above..carb, cam , manifold

Transmission �
model / type = ford toploader
Modifications = trans tunnel??? clutch actuation?? tailshaft??

Differential �
model / type = ford 9�

Vehicle ride height �
OEM height to top of roof = homework time
Modified height to top of roof = homework time

Front suspension � For most of this it is OEM V8 stuff..so I wouldn't say its modified.
Will the suspension be modified =
What mods = stiffened, suitable for V8, height raised to OEM or slightly below
Will the vehicle front suspension be raise = I think they mean raised past STD...not raised back to STD
By how much ??? (depends that the minimum is ??) Minimum is 2/3rd original travel with 100mm ground clearance..but check that for WA
How will the height of the vehicle be altered?? =
Suspension springs = equal to OEM
Spring height from original = homework time


You need to find a copy of someones who has passed or speak to an engineer...thats what you pay them for.

The 265/40/17 will require an 9.0-10.5" rim. They would have to accept the A9X base tyre as a 205/70/14 for the 265/40/17 to be legal.
The 245/40/17 will require an 8.0-9.5" rim.

300HP = 223kW

as above, ive herd of people being knocked back for 8 inch rims on a torry. Also the hole in the bonnet will have to seal around the air filter. Aparantly it must seal incase a hose blows and throws water over your windscreen.

Good luck anyhows.

Evan.

[ls2lxhatch]

An 8" rim was the maximum before the NCOP was introduced.

The only requirement for rim width under the NCOP is that is must be within the tyre manufacturers recommended rim width range for the tyre fitted.

The NCOP tyre size is restricted based on the largest optional tyre fitted by the manufacturer for that model.

(SS CR70H13 ~ 200/70/13 ~ 610 mm)
(A9X DR70H14 ~ 200/70/14 ~ 636 mm)

The maximum tyre width is 1.3 times the widest tyre and the maximum diameter is + 15 mm.

There are two problems.

1. Which tyre you are allowed to use as the base tyre. A9X, L34 or SS.
2. The dimensions of the base tyre as the conversion from the alpha numeric tyre sizing to metric is debatable.

If they accept the A9X tyre is 205/70/14 the you could have 205 x 1.3 = 266.5 wide tyre.
It is more likely they will consider the A9X tyre to be 200/70/14 in which case you can only have 200 x 1.3 = 260.

Jack is top of the list

Of people I wouldn't use

Last I saw him he had no testing equipment and not much idea of what fits what

Theres a few more on the list I'd go to first
Post a pic of the list and I'll see if any of the old boys I remember are still on it

I filled my own forms in and got approval for 17's 255's and 350 cubes
Subject to a letter from a brake specialist for the AP brake mods or engineers tests
And since I was the only guy writing the letters.... the brake parts easy for me

[dattoman]

Wow the list has changed alot

Romeo or Dan would have to be my choice out of those

There was a father and son team who don't seem to be on that list

[Evan]

im not completly sure to be ohnest. That was just what i was told. Maby give them a call.

ive never even tried to go over with my wide rims and tyres on.

To make life easy ive always just taken the Torry over the pits with my mates 225's with stocko rims on it.

They always laugh and ask what i usually run on it.

Evan.

[tinkers]

Both topics merged into one since you started both and are on the same subject.

To answer your last question. Governments need to look like they are doing something for their fat pay cheque, so filling out useless forms, means they have done something useful. (or so they think)

[ls2lxhatch]

You only need to fill on the form for modifications that require certification. For example if you look at page 3 of this document you will see there is a list of modifications the do not require certification and a list the do require certification.
http://www.infrastru...ng_3Feb2006.pdf

The rims and tyres do not require certification.

Fitting a 308 does not require certification but the car will have to go over the pits.

Fitting a transmission that was not an option requires certification. eg TH350
Fitting a diff that was not an option requires certification. eg Anything other than the banjo.
http://www.infrastru...ns_3Feb2006.pdf

Fitting brakes that were not a option requires certification.
http://www.infrastru...ns_3Feb2006.pdf

The whole point of filling out the modification application is that they will then give you a list of mods that require certification and direct you to the relevant documentation. It is safer to just list everything you want to do even if it does not require certification. That way everything is in writing and you will have confirmation that you have not misinterpreted the NCOP.

Have a read of page 11 and 12 of this document.
NCOP6 Section LH Body Modifications 3 Feb 2006

There is no mention of rear opening scoops being illegal, in-fact they show one in their examples. One interesting point is that if anything protrudes through the bonnet it must be covered by steel. This would indicate that a fiberglass scoop covering an air filter that protrudes through the bonnet is not legal, of course this would not be an issue with EFI. You could run into problems depending on how much reinforcing has been cut out and what has been done to maintain bonnet strength.

There was a time when rear opening scoops were illegal in WA. Under the NCOP it would appear that is no longer the case. A call to an engineer or the Perth Tech section 9216 3880 should clear things up.

One question,
may help, or not, don't know.

Is a "toploader" a Ford gearbox or a Borg Warner gearbox?

As GMH uses BorgWarner products.

Fraud

[ls2lxhatch]

If the gearbox was a factory option for the car in question then it does not require engineering. All other gearboxes regardless of manufacturer will require engineering.
