Mark Skaife shows Michael Caruso around the car he drove to victory in the 1991 Bathurst 1000, the legendary Nissan GT-R R32.

So michael were up to speed with the alderman technology but this little beast back in 1991 there was a fair bit of work going on because when it arrived from japan it was clearly a lot different to how we ended up winning bath us in 91 and then 92 so even the simplest things that originally arrived with a 14-inch front brake rotor so we had to go to a fourteen

Point eight inch brake rotor we did our own wheel so our company and adelaide csa made the wheel for us even in terms of just the australian ization of it we did all the turbos we did all the engines we did all the amala gatien for the front in terms of all the inner core’s it’s a very you oh actually not a bad hit for me now you wouldn’t like to have a side

Intrusion crash of the day would you know look at some instantly feel a little bit less safer than what i knew so that’s a sure but there’s nobody the amount of bars and and clearly even the simple things we didn’t have a cross in the door good for driver changes yeah i was just about to say yeah when you’re a bad person you’re going to do a driver change in 15

Seconds that’s not bad but i mean straightaway i’ve been obviously you’ve still got the dash in the car from how came standard a bit of a change in the the motek beat walking it what can you tell me about you know this gear secret widget that’s a method spacing as a car exactly so we did our own gearbox it was a hollinger gearbox this is a six-speed and this one’s

A 5-speed in the previous model don’t box you know they were really hard and clunky on paris and exactly a little work a lot of this area in here in behind that panel is where the bus which was are the drivers they’re only me aware that whoa yeah that was the reach lubed up so on full boost we could run about one at a 1.9 bar and that was almost 700 horsepower and

As a racecar in aeterna co-champion round we’d run 1.2 1.3 bar and that roughly had 600 or so at that time and to put that into terms like even now we’re not we’re just getting to that point of nee 700 horsepower so to have that are 25 years ago and we’re still to today exactly at that point that’s that’s pretty special so this was the really cool one so where that

Set out there now is the lowest for drive mode and then if it rained it clicked it all the way around and that was full four-wheel drive i wonder if it was pretty burly wall in the way there was a lot less carbon fiber and a lot more which we did in what i would call just genuine fabrication so all the air filter system all the turbocharger plumbing the way that

As i said we australian eyes dit was extraordinary and the the durability imagine making all this stuff each time and every time it fits that all these hangers because the turbos used to drop okay so can they got so hot that the manifold that actually the turbos add sag yeah yeah the way that we ended up achieving the you know the durability was just a massive

Amount of work and that’s one of the real travesties around what’s actually taking place was when the car was banned you can imagine the amount of work that an hours involved to get it to wear was exactly and when we converted as a team to the v8 regulations there is nothing not one single part of the stuff that we were able to develop you could use we were the

First ones to run a centralized pot and the submerged pumps and the submerged pumps have pumped that in and have basically a full center which was the one we had the reserve washing in yeah exactly and and we had the first ones that had the little transponder in them that actually had a little thermo setting on them which was just a resistor that had it was covered

With fuel than you knew that you had feel in the fuel tank so it was pretty basic stuff but in those days we were the first to runner so a half-a-million-dollar race car in 1990 or 1991 was was like a two or two and a half million dollar car of today so you know the car when it arrived from japan and had all the speed stuff you know the crucial bit of the twin-turbo

And the engine power and the full drive were all great it did actually have four-wheel steer we assume it’s not bad all right but if you think about what had taken place and how hardness and motor company work with japan to you know get the car to being a race winning car just fantastic
