Putting my ignorant head above the parapet here (cos i know some of my fellow PHers are very sensitive and passionate about their GT 911s) can anyone explain in simple terms the differences between the 911 models GT 1,2 and 3? (i assume all are versions of the 996 - if there are 993 GT1,2 and 3 then I really do give up)

are they normally aspirated, turbo'd, stripped down, or what?

and a specific second question; I noticed in this months Porsche Post that Strasse are offering a 996 GT3RS which I assume is a stripped down race version of a GT3 (whatever that is) as its got a roll cage. So if its an RS why a CD and air con. Errr....???

996:
GT1 - No such roadcar, racer only
GT2 - Widebody, RWD Turbo 480?BHP
GT3 - Narrowbody RWD N/A lighter shell etc
GT3RS - As per GT3 but a bit more hardcore.

This is a road going 993 GT1.

Rather rare road going version of the Le Mans race car, based around an 993 shell, the engine is mid mounted twin turbo'ed producing about 600 bhp.

Hmm I recall the 993 GT2, which was a bit lairy and rather tasty but I'm sure the hot NA 993 was an RS not a GT3 ?

ok, I think I'm getting it. GT2 is a turbo, presumably however it differs in other ways from a standard turbo ie lighter, uprated brakes etc?

and a GT3 if normally aspirated must differ significantly from a standard 996 again in terms of what? power output, suspension, brakes? in other words, what justifies the large gulf in price between standard 996 and GT3.

Sounds to me like they are RS versions of their respective road going brethren, in which case what else is done to a GT3 to make a GT3RS? and if youve gone to the bother of "RS"ing a GT3 then why on earth then bolt on aircon etc.

There was also a 996 GT1 - www.autofarm.co.uk/car.php3/gt1r.html

The closest to a 993 GT3 was the Carrera RS - a toned down version of the 993 GT2.

The GT3RS has a carbon fibre bonnet, wing mirrors, rear wing and boot cover and a plexiglass rear screen. The suspension and pick up points are from the American Lemans winning RS racing cars which was homoligated on the GT3RS to allow Porsche to use the suspension on the FIA european endurance series and le mans. It will also form the basis for the 997 cup car. It would cost far more to convert a GT3MK2 to RS spec than the marginal increase in cost between the two cars. So if you want a road/track car the RS is the better choice.

Air conditioning was only an option on UK cars and with so much effort made to strip weight from the body shell, your guess is as good as mine as to why it was offgered. I will forgive them a cd player.

I didn't tick the air con box when I specced my car.

The 996 GT1 was just a cosmetically updated 993 GT1

thanks for that, the fog is clearing. so essentially the differences between GT3RS and standard GT3 are in terms of further weight reduction in the interior and bodyshell (via carbon fibre panels), and the inclusion of a race suspension.

but what are the main differences between GT3 and standard? is it just that its lighter or are there differences in engine spec etc

actually the GT3 is heavier than a standard C2, AFAIK it's due to extra stiffening

The GT3 engine is a bit good! The standard 996 engine made around 320 bhp, the GT3 engine is lightened, balanced and designed to rev much higher etc.

It pushes out around 380 bhp. The body shell is stiffer than the standard Carrera and the suspension is firmer and more track biased. The brakes are uprated or in the case of the GT3 RS they are carbon ceramic.

Its rather special, its the 911 in hardcore form!

Has anyone mentioned that the GT3 has an engine based on that of the GT1, not the 996?....

The GT numbering system comes from the Le Mans GT classes in which the cars were eligible for (except the GT2 which I believe was never actually raced).

All the GT cars share the same basic engine which is derived from the GT1 - the TT also uses this and is no relation to the 996/997 series engines, in fact to some extent is an old 964 race car bottom end with a water-cooled head grafted on.

The GT2 differs from the Turbo in that it is only RWD, no PSM/Traction control and has some sportier bits which are shared with the GT3.

The GT3 was originally built in 99/2000 as a limited edition - comes in 2 forms, the clubsport and the comfort. The original Mk1 clubsport was very light and weighs almost the same as a Mk2 GT3 RS. You can read about the Mk1 here:www.titanic.co.uk/GT3/GT32e.htm

The GT3 was then re-released for the Mk2 and put into full production (i.e. unlimited numbers) and was given an extra 21bhp, but was heavier. The GT3RS is basically a lightweight Mk2 and shares the same engine (on paper).
