Bright green and ready for battle — Joseph Curphey’s Japan slider–style Silvia is ready to shred!
I was planning on feeling out the car, getting everything up to temperature, and then coming back in for a bolt check. I thought I’d give it a small clutch kick and see how it felt in a drift. Immediately, I was hooked and ended up drifting the whole session,” Joseph Curphey recalls of his first shakedown.
Before we get ahead of ourselves, though, we need to take a step back — right back to the beginning, way before the existence of this bright green S15 sprawled out on your coffee table or workshop bench.
As it will have been for many of you, Joe’s first-ever performance car was the easily obtained Nissan Silvia S14. Although we won’t mention how long ago that was now, that S14 was an incredibly special one, and Joe owned it for several years before dropping in one of the greatest-sounding engines of all time: Toyota’s 2.5-litre, in-line-six 1JZ. In the end, the S14 was sold on, but Joe’s passion for drifting, driving, and modifying flourished and finally led to the building of a street-spec Toyota JZX110 drift car.
After daily-driving the JZX for some time and attending a few club-level skidpan days, Joe found himself at Bruce McLaren Motorsport Park attending a D-Club Pink Style drift event hosted by a few close friends. An incredibly rad time was had, but, for Joe, something wasn’t quite right. Although set up fairly well, the JZX110 platform wasn’t quite giving Joe the experience that he was after. His S-chassis roots were calling.
Fast forward a few moons, and Joe found himself trackside at one of New Zealand’s most popular grass-roots drift events: Spring Matsuri. With the JZX110 out of action, Adam Hedges threw Joe the keys to the C’s shop car.
“After Adam let me drive the C’s Garage S13 shop car in Taupo, I fell in love with how the car was so well set up — especially compared to my JZX110,” Joe explains.
It was at this moment that the towel was thrown in on the JZX110 build and it was pushed into the garage, destined for cruising duties.
“I decided to start looking for a straight rust-free S13 shell. After looking for several months and getting more and more impatient about finding one, I decided to get a newer, less tired chassis: the S15.”
The hunt began, and within a few months a fairly stock red Silvia popped up. Besides OZ Racing coilovers, some GT-R wheels, and some basic engine upgrades, this S15 was exactly what Joe was after. After looking over the car for 15 minutes, Joe did the deal — without even taking it for a test drive.
“Within half an hour or so of my ownership, the interior was already being pulled out, along with all the wiring and sound deadening. The car then went off to SMS Fabrication, where we stripped it to a 100-per-cent bare shell. From there, Adam Hedges started to work his magic,” recalls Joe.
The S15 was clearanced for extra lock; the tunnel was bashed and smoothed to make way for the new gearbox; and the rear quarters were cut, welded, and smoothed to accommodate the bigger tyres and suspension travel for which Joe and the team were aiming. The front end, from the firewall forward, was then seam-welded for added rigidity, and a TIG-welded eight-point roll cage added.
With Joe’s final vision locked in, the Origin widebody kit that he’d stashed away was trimmed and cut into shape, followed closely by the D-MAX Type 3 bodykit.
“With the help of a few friends, the interior of the car was painted in Toyota silver by Vince at Vinceparts — it was the same colour as my JZX110. The car was then taken to Accident Repairs in Glen Innes, where Tim painted the car Porsche Green before it was taken back to SMS Fabrication to be assembled for the final time,” Joe told us.
With the suspension, chassis, and exterior complete, it was time for a motor worthy of the time and effort that had gone into this build. Joe managed to hunt down a forged SR20 engine for a steal. CP pistons, Eagle rods, and ARP fastening ensured that a decent amount of abuse could be thrown at it. Helping cylinder-head flow is a pair of Tomei Poncams and HKS cam gears. And sitting mid-mounted on a custom C’s Garage manifold is arguably one of the best mid-power turbos for the SR20 engine: the Garrett GTX3071R — chosen for its ability to make decent top-end and mid-range power, without sacrificing response.
“After the car was fully assembled, I made the trek down to Wellington, where Geoff from NZ Wiring and Performance wired in the Link Monsoon ECU, AiM MXS Strada dash, and MoTeC PDM [power distribution module]. None of the factory wiring remains, other than that in the doors,” Joe says. “Once it was all wired up, it was pushed across the workshop to where Chris at Prestige Tuning & Motorsport tuned it. The car churned out 366kW and 623Nm of torque before the clutch started slipping, when we called it a day.”
After getting the car back from Wellington, Joe took it to C’s Garage HQ, where the final touches were completed. The kit was trimmed to make sure that there was clearance with the extra lock, and several checks were made, ensuring that Joe’s first drift day in the car was a success. Then, just like that, it was slide time. Joe booked the first day possible at Hamptons.
“Immediately, I was hooked! I ended up drifting the whole session. After coming back in and walking around with a stupid grin on my face, it was time to go back out again. After four sessions in the car that day, I was getting more and more comfortable, but then it was time to call it a day,” Joe tells us excitedly. “The car is unreal, and everything I wanted from this platform. It reminds me of my S14 in a way, too.”
Having been so unfulfilled drifting the JZX platform, Joe would seem to have got his groove back. And it’s unlikely to wane anytime soon, surrounded as he is by a talented group of mates willing to go that extra mile to see his dreams materialize. This S15 is something all involved can be proud of.
Whether you build it, buy it, or both, keep hunting for the car that best fits your groove — never stop hunting for it. Because, when you have it, all those late nights, long weekends, and busted knuckles will have been worth it!
