It doesn't really matter what's going around the track cause it's all entertaining :) Even the sound of an Alfa GTV climbing out of a corner with it's carby throat's wide open or the thump of the ol XD....... Sweet !

IMHO, these are race "CARS" ! Unlike those things that "look" like cars that race now days :P

I'm with ya mate!

I went to my first historics at Sandown last year, and it was a top experience. Sensory overload!

Light years difference in the cages and the way the suspension is set up...they spend scary amounts on shocks these days.

So Terry has fixed the ol RB20? Be good to see the cars out running around...is there a chance that both Sydney R31s will be coming down?

Ok so the cages are different but surely quality of cages these days cant make the car that much more ridgid.

Going by the smack that everyone is talking in here, u could put a 2000 onwards cage and shocks in a gtr and hose the gibson car.

somehow i dont think so...

You would hose it the Gibson car. Remember back then you had Yoko fighting Bridgestone fighting Dunlop. So tyre development was helping the cars. These days with control tyres you are not going to get the tyre development.

Imagine a GTR with stiffer chassis so they can tune the better shocks to hold the road better and get more out of tyres that are much better then what they ran on in the day (Assuming the tyre design is suitable for the car)

On top of that you now have turbo technology that would allow them to run higher boost without bearing failure (should the rules permit more boost) and at a minumum more effecient turbos and ECUs.

I think there would be a few things that would add up to meaning that if you built a Grp A GTR today with what current practices and technologies they would be quicker.

Think about it, they only have to be half a second per lap quicker to win by 20seconds in a typical race...thats a killing

...and do we know for sure about the 3 R31s? I will confirm this weekend if the Vic car is to be run. I cant see him running it if he hasnt given a shakedown at Calder.

Cheers Roy,

going by these comments and others in the thread it seems as though u could make a gtr these days with the same peak power because everything else would be so much better u could put non slick tyres on it and still be faster

Now that would be cool.

I think a lot of the GTRs getting around Vic have similar power to the Winfield car. Difference is in the fact that they still typically run performance street suspension, not competition suspension and the weights and chassis rigidity of the cars are not as good.

And no disrespect to the owners but i think they will all concede they are 1-2 seconds off what a professional driver would get out of the cars.

That all said there are GTRs doing 1:18-19s at Sandown on road rubber and full weight and 1:30 flat at Winton and 1:42s at PI. So they are BS quick considering

SK, they are nice pics, but you'd have to admit, there's nothing like seeing it in the flesh ;)

I've spent so much time just looking over this car, admiring the craftsmanship and attention to detail. And as good as it is from the top, the underside is just as amazing ( which I think you've seen from memory ? ). It's funny though, how many people rock up and say it's much smaller than they expected :rant:

2630GTS, you have to remember what this car was built for and what was available / allowed at the time. :no: I would LOVE to see what Fred Gibson & his crew would build with today's parts ( and a full Nissan factory budget ). Could you imagine his take on the R34 for an attack on Bathurst :yes:

Roy, I'll talk to Terry today and confirm the Sydney cars.

I heard that when a a V8 supercar is built the test how much twist the chassis has by using XX amount of force to make a 1 degree twist, after 12 months it is tested again and surpirsingly it takes something like 1/3 less force to make that 1 degree change.

Hence a 15-16 y/o care probably has a HEAP less rigidity.

im no expert on the situation, thats just what I was told by a guy who would know.

None the less I love the old Gibson GTRs and they will always be a favorite car to me.

I went to my first historics at Sandown last year, and it was a top experience. Sensory overload!

I used to go and watch them when they were cutting edge touring cars, not historics. And yeah, it was a spectacle.

Quite a sight to see a Volvo 240GT two wheeling around the esses at Surfers Paradise

Great to see an M3 take the GTR under brakes into Hungry Corner at Lakeside

A bit deflating to see the relatively underpowered but pretty HR31 get belted by Sierra RS500s. There was only ever a max (that I can recall 3 HR31s running - two Peter Jackson Racing, and Murray Carter as a privateer)

And a lesson in engineering superiority also to see the GTR absolutely trounce everything off the line and then pretty much control race pace. Fast, professional, everything they should be, but sadly never hit the mark for aural entertainment like a V8.

Are the Group-A GT-Rs like 1200kg? Or something like that. Under 1300kg's if I remember reading somewhere.

I'd have to go back a bit to remember, but I believe on introduction they were over 1300kg - engine equivalence factor put them in the same weight class as the destroked 4987cc Commodore. Then they were ballasted and de-boosted to nobble the advantage. I believe that come Bathurst 92 they were weighing 1500kg and suffering brake problems as a result.

Hmm, maybe my memory is playing tricks on me, but I don't remember Murray Carter ever driving an HR31. I thought it was a DR30? Chris Lambden (Not sure of spelling) had an HR31 in Beaurepaires (Spelling not getting any better, is it?) colours. He now is editor/owner/something important in Motorsport News fortnightly magazine/newspaper.

    • You're not the first person that's said that about this car lol. A Touring wagon GT in Spark yellow mica would be the dog's danglies 😆 I will keep an eye out for a future purchase for sure. The seats are almost like the OEM Recaros... electric adjustment for fore/aft and tilt movements except reclining.   
    • Yes!! I love these! It's a shame its not the wagon though!   Thank everything that's holy that it doesn't have the interior of the Aussie delivered ones. Those seats are so much nicer.  
    • I'm both sorry and thankful that you do that. 
    • 2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers. 
    • Wow, even with the Audi logo centre caps. I love OEM wheel mismatches.
