Friend of yours the buyer/seller? I wonder where the market's at for them atm, I know one sold for 180k ish 18 months or so back.
Never ceases to amaze me that there are 17 of these tucked away in Aus. Although, we seemingly love our GT3s down under - it is rumoured that the city of Adelaide alone has eight 997 RS 4.0s - that's a lot for a city of 1.3 mil!

Indeed. Looks somehow unaffordable, though ;-)
It's hard to believe that the difference to the normal 6GT3 is that big given the few modifications but everybody seems to agree here and in other forums.
Also, I red the other day that Porsche consciously picked engines at the upper end of the power spectrum for the RS. Would explain why most RS owners can achieve higher maximum speeds (the previous owner of my 6GT3 told me he reached 320kmh (speedo) with the 6GT3 vs 326kmh with his 6GT3RS) despite the large spoiler.

Only 682 produced. Not because of limited production. No US cars and lack of road comfort kept sales down.

I don't see how the RS can have different cylinder heads, yet the motors were pulled from the regular GT3 production line as strong performers on the dyno. Did they pick the winners, then disassemble them and rebuild with RS parts? Sounds unlikely...

I have never heard this before! Sounds unlikely. I've heard that the RS engines had a lot more hp than the stated 381, but Porsche has always been conservative with hp numbers.

Look in the PET (Parts Catalog) for the M004 build code, you will find every single spare needed to build a GT3 RS from the engine to the stickers.
Engine has different parts to allow further developments for the 2004 RSR race car (new homologation). The wheel carriers are also different probably only for that reason.
The story about testing the engines and putting the stronger ones in the RS cars falls in the "urban myth" category in my opinion. We hear the same about the 1999/2000 GT3 production ("better engines went into the M003 ClubSport cars"), but there is not evidence supporting that fact.
The only fact is :
- On a 2000 GT3, the M003 "ClubSport" engine will be fitted with the lighter single-mass flywheel, whereas the M002 "Comfort" engine will have dual-mass.
- On a 2004 GT3, the M004 "RS" engine will be fitted with the lighter single-mass flywheel, whereas the M002 and M003 cars will have dual-mass.
So for each generation of cars, you might find that the 2000 ClubSport or the 2004 RS engine will be slightly stronger compared to its regular peers just because you have less inertia in the flywheel, not because the actual engine has been tested and allocated to that specific car.

The RS (short for the German RennSport, literally "racing sport" in English) is mainly a carryover of the Porsche 911 GT3, albeit it is lighter thanks to a polycarbonate rear window, carbon fiber hood and rear wing. Porsche Ceramic Composite Brake (PCCB) Carbon fibre-reinforced Silicon Carbide (C/SiC) ceramic composite brakes, which are also more heat and fade resistant than the cast iron units fitted as standard, were optional.
The RS has a slightly different engine specification to the GT3. The cylinder heads of the GT3 RS have reshaped intake and exhaust ports for race homologation. Porsche claim the same 381 hp (284 kW) power output as the standard GT3 but Porsche's control dyno showed a jump to nearly 400 hp (298 kW)
The RS has progressive springs rather than linear. The dampers are uprated and are between 10 and 15 percent stiffer than the normal GT3 in bounce and rebound.
The wheel carriers are totally redesigned to maximize the improved dynamic camber control. The suspension top mounts can be turned 120 degrees to a cup car position. Both front and rear control arms are adjustable. The RS is 3 mm (0.1 in) lower than the standard car.
The RS rear wing delivers 35 kg (77 lb) of downforce at 125 mph (201 km/h). The RS has ram air ducts on the engine bay which force air into the intake with 18Mb of pressure at 187 mph (301 km/h) and this is enough to create an additional 15 bhp (11 kW; 15 PS). That extra bhp cannot be homologated since the official engine output figures are certified on a dyno.
Only 140 right hand drive GT3 RS cars were built by Porsche and 113 of those were officially imported into to the UK. The GT3 RS was not sold in USA or Canada.

Thanks Das Chin! Very informative. So it appears with some suspension tweaking, heavier spring rates, proper alignment, a larger rear wing, 150-200 Lbs in weight savings, better rotors and pads, Clubsport seats and rear roll bar with harnesses, and maybe an ECU tune, we get within 98% of the RS as relates to performance. Now, we all know that VIN is King, so no way to get there, but from a drivers perspective, the standard MKII can be made to achieve very close to RS standards...
Sweet!!! We do get AC as standard with the normal GT3... so take that RS ![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
