What do you mean "completely different" ? Do not want to sound pedandtic--- but I cannot understand how you are asserting this.
BTW -- CS-- did you recently acquire RSR?

Peter R.

I don't know if VarioRam RSR's exist. The ones I know of ( and I'm a bit of a dufus) are the 3.8's without the hydraulic valvetrains and the 'non vario' intake headers. They were also available as a non-race 3.8 factory upgrade and had 285 bhp as opposed to the 272 bhp from the standard 993, which does have the hydraulic operated valves.

I have owned numerous 993 RS CS,993 Cup, a factory genuine RSR and still own a RS upspececd to RSR spec-- and would swear they were varioram!!! So I am struggling with the assertion that RSR was not varioram. The RSR is not to be confused with that name attributed in the UK to the RS CS erroneously . The 993 RSR was built in limited numbers(28) as 1998 models built at the end of 1997.The performance of the engines was the best of any N/A 993 -- the best part of 380HP (real world HP) and far better than normal RS CS numbers.My RSR was dynoed for new owner at point of sale and produced just short of that number on that day.I have dynoed numerous other N/A 3.8's that produced about 20 less Hp-- despite the best of everthing in them. Looking at HP claims in the US you could probably add 10% to get a conversion number!

In that the inlet system is not the same as the varioram one even with ths solenoids removed etc.......That is another Paul who has recently acquired an RSR, I saw it at Silverstone a couple of weeks ago...magnificent piece of kit, fantastic noise

Red9

That Paul(as in " another Paul") will verify what I am saying. He has owned a few of the RSR's -- the genuine thing-- and that car has a vario--- I presume that is how he bought it-- previous owner was playing with ITB's to see comparison.

Peter R.

So what you are saying is that the RSR's we know are actually RSCS' but since we didn't have RSCS's we got erroneous RSR's ? And who made the Error ? The blokes in Stuttgart or the blokes at the distribution end ?
This is all very confusing .

RS and RS/CS were the first to use v-ram in '95. Then the all 993 got it in '96-98

RSR used this, not vram

Looks like something out of an Alien movie, wheras the 'normal' vario looks like a headcrab out of Half Life.

For the UK, Porsche produced 7 rhd RSCS, these were known as RSR, the apparent reason for this is that the Clubsport of the time was a 968, available for a lot less ££$$......the story is that Porsche used that name put a distance between the cars as the asking price didn't fit in with the no frills 968CS.......whether this is true or not...who knows, it is now almost Porsche forum legend in the UK

The true RSR was the race car mentioned above.

I can't dispute this but also have never heard this version of 993history

Not counting the normal production cars or the GT2, there were 4 sporting versions w/ sub variations in each.
993RS(M002), 993RS/CS(M003), 993 Cup(M????), 993RSR(M????)
the transmisssions respectively were G50/31, G50/32, G50/30, G50/34
the engines respectively were M64/20, M64/20, M64/70, M6480
nominal cr 11.3, 11.3, 11.3, 11.5
nominal hp 300@6500, 300@6500, 315@6700, 340@7000
nominal torque NM 355@5400, 355@5400, 370@5700, 380@5500

I vaguely remember seeing a car billed as a 993 RSR. It looked like an GT2, but had a non turbo engine. IIRC it had the big wing with the two air intakes, the bolt on fenders and the big front spoiler.

I think there's a Belgian team that still races one, but I can't remember which.

Does this sound like the RSR you are talking about ?

RSR







The RSR does look similar to the GT2 differences beside engine and transmission are the spoilers

Peter R.

Since im halfway up the learning cuve anyway, Bill, I notice from your avaar that your RS side skirts are color coded.
The ones I see here (if i see one at all) have black unpainted ones (looks like).

Peter R.

Bill Verburg

they came through black from the factory, I painted mine to match the body color, JMO but I think it looks nicer
