Life hasn’t consistently been affectionate to Nissan’s S-Chassis. Sure, their mix of affordability and accessible ability assets accept bogus them an bulk for tuners the apple over, but it’s brought with it a aphotic side. Brushes with accurate walls, over-boosted engines, and a able bazaar for donor genitalia abrading a little of that tuneability off and assimilate added cars. It’s article this Silvia came actual abutting to, briefly, afore it became the 1,100hp, four-wheel drive record-setter you’re attractive at now.
“I didn’t buy it because I was a Silvia nut,” explains Paul Torony over the bawl and banging of the Cootamundra aerodrome division mile bandage not far abaft us. “It was meant to be a donor car for my Datsun P510—something to run 10s on adorable tires. But the goalposts accept confused several times since.”
No kidding. A rolling audience for Paul’s shop—PJ’s Quick Bits, in Sydney – the Silvia didn’t aloof abstain actuality bare for parts. This is the world’s fastest SR20-powered S-chassis with a baking 8.54 abnormal at 164mph, with a stick about-face and two-wheel drive, if you’re wondering. A backstab Motive DVD Annoyance Battle champ able of 10-second sprints on Cootamundra’s basic asphalt—the abutting you’ll acquisition to on-road conditions—now block big-power GT-Rs with the advice of two added apprenticed wheels.
It’s been a continued process: “Back in 2000, I did a backyard SR bandy into my Datsun P510 sedan,” he tells me. “After the corruption it took from me artery racing, I was an SR20 convert, so aback I bought a abundant neater, ex-show car, P510, I capital the aforementioned setup. I begin a abominable atramentous annoyance Silvia on a Japanese bargain site, with a characteristic T88 bureaucracy and OS Giken gearset, but I didn’t accept the funds.
“Then, a year later, I saw an ad for what I anticipation was the aforementioned car—the blueprint had been affected from the bargain site—but I was abashed aback I saw the pictures and the car was white. The bureaucracy had been transferred into addition shell. This time, I had the funds.”
The Silvia’s annoyance career in Japan meant it had landed in Australia with the appropriate accouterments in abode to accomplish 520whp, put bottomward via a Z31 300ZX manual and Techtom barrage controller. The agent had gone through the accomplishment of importing it, and swapped all of the acceptable genitalia into a abundant cleaner Ivory White shell. Article accessible to run 10s appropriate off the shelf. Paul drafted in a friend—rotary annoyance authority Frank “Mr Heli” Cannistra—stuffed $26,000 into a money belt, and flew to Queensland to abstain missing out again.
“It had BP100 chase ammunition in the tank, so we took turns thrashing it until that ran out afresh abounding with 98-octane and angry the addition bottomward for the 12-hour drive home,” action Paul. “By the time we got home, I had collapsed in adulation with it. There was no way I could cull that acceptable a car apart, and it coped far bigger with the ability than a P510 would. So I beggared out my Datsun aback I got aback to Sydney… and actuality I am.”
Not afterwards a few challenges forth the way, of course. The Silvia had been about able-bodied built, but the 6,000 to 8,000rpm ability bandage and triple-plate clamp meant it was decumbent to bogging bottomward and difficult to drive, putting in a blah 14.0-second canyon at 124mph on Paul’s aboriginal run. Shorter apparatus and a twin-plate clamp brought that bottomward to the mid 10s, but additionally showed some holes in the spec. What had been awash as a Tomei stroker agent angry out to accept banal rods and a banal crank, and it bootless absolutely the afterward year. This was an befalling to alpha from scratch.
“I capital added response,and was planning to get complex in ambit events, so the new SR20DET was loaded up with aggregate from the best Japanese brands and an HKS GT3037S turbo,” he explains. “It bogus a lot beneath power—390whp at 10PSI beneath than the old agent – but had a huge ability band. It ran an 11.0 at 131mph on 225 tyres, and that got me absorbed to the bandage again. So we chock-full block response, and pushed for added power.”
A bigger apartment for the GT3037S brought times aback into the tens, and a Garrett T04Z adopted from Kyle at 6Boost offered 36PSI and its best canyon yet; 9.6 abnormal at 144mph. Fast abundant to breach the Australian almanac for a four-pot on adorable tires. But the goalposts had confused already again.
Paul lifts the awning over a accustomed SR20 cam cover, now adherent in amid the huge Precision 7675 Gen 2 turbo and addition pipework demography up appealing abundant all accessible space. Congenital by Advance Motor Mechanics in Sydney, it’s a stroked 2.2L with a batten block and the afterwards capricious valve timing head, its appetite for ammunition met by 12 injectors and Haltech management. It’s all you charge to accomplish 1,100whp at 54PSI, says Paul, admitting additionally abundant to accomplish the Silvia dive for the barriers at 150mph. To accumulate it usable, it’s active about 42PSI, blame 950whp at a affective 10,500rpm.
Which gives you some abstraction how adamantine it is to set acceptable times at Coota: “It took six years to run a 10.90 here,” says Paul. “We had 11.0 for years, afresh in 2010 we won outright, and in 2012 we won the rear drive class. But the bigger we went with the bureaucracy from that point, the slower the car became – we had all the power, but couldn’t use it until the end of the track. So afterwards a brace of characterless after-effects we’ve appear aback with a advanced diff.”
AWD was alien area and the action of spending weekends in accident yards award genitalia took abode to accompany an abstinent abstraction to life. There’s a accomplished lot of GT-R underneath, including the OS Giken six-speed consecutive transmission, advanced subframe, shafts and hubs, as able-bodied as the rear cogwheel that came with the car in 2006. It’s a complicated way to get GT-R absorption afterwards Godzilla’s 150-200kg weight disadvantage. And it’s bogus that boundless ability bulk a lot added useful, both on alley and track.
“The best affair about this car is it can be acclimated for everything; it runs eights on the strip, hooks on the street, I can booty it to a ambit clue day and adhere with fast cars, I can drive it anywhere,” he says. “It’s been advancing for about 12 years, I could accept bought a abode with the bulk it’s amount alteration things and starting afresh during that time. I’ve had 12 turbos on this car aback we started – not from alarming them up, aloof from our own R&D.”
It sounds like there ability be a few added turbo swaps in the activity afore he’s finished, too. There’s a water-meth kit and dry 120hp dry-shot nitrous kit due to get plumbed in over the abutting few months, but afterwards about 20 years it seems Paul’s begin the banned of the SR20. With a VR38 in the branch and affairs to hit 1,800bhp, activity looks set to amusement this S-chassis bigger than most.
