Which is the better track car?

 

Stock GT2RS, but with same money spent or a GT2, the GT2 can be modded to be much faster than the RS..

 

Some of the guys on this board like to go overboard... In reality, neither car "needs" any "improvements" for track duty.

 

Don't agree with that statement at all.

 

I think you're proving his point!

 

Not really.

Coolant pipes. LSD. I wouldn't touch a track without taking care of those.

Shock valving is awful. Keep it if you like porpoising down the track at 150+moh.

Roll bar and 6 pt harnesses.

That's the minimum.

 

In other words, fixing broken components/preventative maintenance. Sure, no argument. Rollbar/harnesses...I mean, how fundamental are we trying to be? Don't forget the helmet!

Not trying to bust your chops, but I just think it's silly when people take an already extremely track oriented 911, and talk about aero work, transaxle regears, ecu tunes, so casually, as if it's just like checking the tire pressure.

 

The 997GT2.2 is the 2009 model whose production started late 2008 after the annual factory shut down.
The visible difference is the PCM 3 and with that came some subtle differences in the software eg the .2 can easily be made to run the latest LED rear lights through activation via PIWI whereas the .1 model cannot.

There were 1261 997 GT2s made with approx 300 being the 2009 .2 versions so they are actually rarer than the GT2RS

In the UK, C16 models (relevant to you) there were 62 GT2 made with 28 being the .2 PCM 3 models

The most important changes to the GT2RS engine wise are the use of different stronger rods and the new intercoolers.

 

What can you do to the GT2 that you cannot do to the 2 RS to make the 2RS an even faster track car? Both are already scary fast!

 

Thank you for the info lads.

Is there anything on what numbers we're produced in certain colours?

 

Bryce86, I would be interested in that info as well. I haven't seen another GT2 in my color in real life, and on the internet I've only seen one or two others.

scss98, to be honest I think the GT2RS base has a lot more potential over the GT2 if you limit it to bolt ons and flash programming. The RS with the lighter pistons and bigger hot sides on their turbos really lend themselves to boost and throttle response. I think Champion got an extra 30-40hp out of a GT2RS with the 68mm billet housings and compressors over my initial 3.6l build with 68mm billet compressors and housings, and they said the boost delivery was better too. How much better? Well, I don't think it's worth the low five figures it would cost to buy the RS turbos and then rebuild them for the 68mm billet compressors and housings. The rest of the car is pretty much the same other than programming and some knick knacks like intercoolers (use whomever you believe). You can add cheese ball red to the interior and Altezza tail lights but that doesn't make it better.

Obviously, if you try to mod the two cars to the same levels- engine build etc. they will come out about the same. Throw enough cash at any car...

 

To be honest I totally agree with your viewpoint but clarification was warranted. Those do constitute modifications and in the case of the coolant pipe fix, I think (no idea if true or not) you need to drop the engine to do it properly anyways, so that's a big fix and not a simple bolt on.

I would even go as far as saying protecting the heat exchangers in the front of the car with grill inserts etc. for track (and even road) is needed (and surprisingly not installed at the factory).

For what it's worth, I've never changed gear ratios on my GT2. Nor have I done any aero work other than bolting on the GT2RS front lip (which for the record is a GRIP of money and not really worth it, other than for looks).

 

Nick you stated that the GT2RS Turbos have bigger hot sides ? Do you have any more info on the specs ? It would make sense then just to buy the GT2RS turbos and mod them

 

hey nick. is urs a gt2 or a gt2rs?

 

There is actually quite a bit more that is different between these cars. Suspension tuning is different with the RS getting stiffer springs and different dampers. Front wheels are .5" wider with 10 mm wider tires and a wider front track. With the Carbon bits, the RS is 100 lbs lighter. Keep in mind that you can buy all the Carbon bits and convert a GT2 to an RS body. The red interior was an option on the RS. You could still get it in all black. The .1 GT2 was the only GT car that ever offered a Bose stereo option (with a subwoofer). RS could only be had with the Sound Plus option. RS had additional delete options available: halogen headlights instead of Bi-Xenon, A/C delete and radio delete.
