S13 Nissan Silvia & RPS13 Nissan 180SX

It’s a profit making process which many car manufacturers partake in. Take one platform and spawn two or more different variants of what is essentially the same car underneath its sheet metal skin. Honda have done it with the Civic and the Integra, Mitsubishi have done it with the Lancer and Mirage Sedan, Proton have done it with the Satria and Putra and the list goes on and on.

One of the more famous platform sharing exercises is perhaps what Nissan has done with the 180SX and S13 Silvia. Both cars are essentially the exact same car underneath, both with very different appearances. Further confirming the fact that these two cars are exactly the same underneath is that Nissan actually released a limited run of the Sileighty (Silvia front, 180SX rear) and the Onevia (180SX front, Silvia rear) to the Japanese buying public.

The two Falken-liveried Nissans we have here are built by Singaporean tuner, Garage R. Built to compete in drift competitions in and around Singapore, these two drift prepped Nissans are built to exacting standards and are loaded with all sorts of juicy, mouth watering JDM performance parts and would get any JDM fanatic frothing at the mouth.

Felix’s S13 Silvia
Under the hood, we have the well known SR20DET engine which has been pumped up with a slew of HKS parts. The block and its internals are largely untouched, but the head has received quite a bit of work. The stock camshafts were replaced with 264º items from HKS and also fitted are HKS valve springs, HKS rocker arm stoppers, a HKS metal gasket and a pair of HKS cam sprockets.

The standard turbo was replaced with a bigger HKS GT2835 turbo which inhales through a HKS Racing Suction Reloaded intake kit. The heated intake charge is then cooled down by a HKS R-Type intercooler kit before it enters the combustion chambers, where the intake charge is mixed with fuel supplied by HKS 740cc injectors, a SARD fuel regulator and a custom made Garage R anti-surge fuel system. Giving the spark plugs a brighter igniting spark is a HKS Twin Power ignition amplifier. The resulting waste gases from the chemical reaction in the cylinders are taken care of by a HKS Hi-Power 409 exhaust system.

Keeping the highly strung engine cool is a Blitz LM aluminium radiator which has Billion coolant running through its innards. Making the Blitz radiator even more effective is a Billion Racing low temperature thermostat and a Billion Racing fan. Last but not least, the engine is governed by a HKS F-Con V Pro ECU while boost levels are handled by a HKS EVC boost controller.

Garage R have also paid lots of attention to the drivetrain to ensure that it would not be a weak link in this drift car chain. The clutch was replaced with a Nismo Super Coppermix clutch and the standard synchromesh gears were replaced with tougher straight-cut or ‘dog’ gears from PPG. Finally, a Nismo GT Pro LSD was fitted to make drifting the car possible.

A drift car needs to be able to handle well to pull off those crazy drifts and giving this Silvia the handling prowess it needs is a set of HKS Hipermax D’ coilovers. For added rigidity and safety a Cusco front strut bar and a Cusco 8-point rollcage are bolted to the chassis. Finally, a pair of Cusco anti-roll bars are fitted at the front and rear axles and a GP Sports knuckle set provides even more steering angle for better drifts.

For better stopping power, Nissan 4-piston calipers are installed in the front, with Seidoya brake pads on all four corners. A set of high friction Project µ brake shoes are fitted to give the handbrake even more bite to allow Felix to pull off sharp drifts without much effort. For style as well as performance, lightweight Gram Lights 57D wheels are bolted to the Silvia’s hubs, but not before they were wrapped in Falken Azenis RT615 tyres.

On the inside of the car, you’ll find two very desirable Bride bucket seats, a Nardi steering wheel which is attached to a Works Bell GT bosskit, a GP Sports gear knob and HKS DB RS gauges.

On the outside, giving this Silvia the ‘show’ to match its ‘go’ is a full Origins bodykit which is made up of the front and rear bumpers, side skirts and carbon fibre bonnet. For downforce, Garage R also saw fit to bolt on a C-West GT wing on the back.

Jansen’s RPS13 180SX
Arguably the prettier looking sibling in this duo, Jansen’s 180SX is also powered by Nissan’s venerated SR20DET engine and has almost identical specs to the SR20 in Felix’s S13. The only differences are that instead of a Blitz radiator, this 180SX has one from ARC. The radiator and HKS R-Type intercooler are also mounted in a V-mount configuration. This gives the intercooler piping a much shorter route to the engine, which improves turbo and engine response while giving both the radiator and intercooler a better chance of surviving a head-on crash.

The transmission in this 180SX also shares the same parts as its Silvia sibling. The clutch is a Nismo Super Coppermix item, the gears have been replaced with straight-cut gears from PPG and also fitted is a Nismo GT Pro LSD.

For handling, yet another set of HKS Hipermax D coilovers are fitted, as are the Cusco anti-roll bars, GP Sports knuckles and Cusco 8-point rollcage. Instead of a Cusco strut bar, a Carbing item which comes with a brake cylinder stopper is fitted.

Instead of the Nissan 4-piston calipers on the Silvia, the 180SX has a set of AP Racing calipers instead. But otherwise, the 180SX uses the same Seidoya brake pads and Project µ brake shoes.

Being teammates and all, it makes sense to use the same wheels as your teammate to keep the theme in place, so Jansen also opted for Gram Lights 57D wheels on his 180SX. Being a Falken sponsored car, it would only make sense to use Falken’s Azenis RT615 tyres.

Inside the stripped cockpit, Jansen’s opted for Recaro seats and Sabelt harnesses and a Vertex gearknob, but the same Nardi steering wheel and Works Bell GT bosskit as the ones in the Silvia are also found in his 180SX.

The bodykit is also from – you guessed it – Origins. The 180SX Origins bodykit consists of the front and rear bumper, side skirts and the carbon fibre bonnet. Also bolted to the back of the 180SX is a C-West GT wing.
