Whats the difference between a GT2 and a GT3?

[Jeroen]

AFAIK the GT3 is fully water-cooled (both heads and cilinders), but it is based on the 964 block (real dry sump, like the good 'ol days)
They don't go "boom" when you drive 'm on the track with sticky tires

The TT and GT2 use the very same engine as the GT3, except being turbo charged...

Thanks Chris for the offer! I might take you up on it.

Thanks everybody for the great info. Pelican Boards are the best. If I wait 3 years and the 997 GT3 is "proven" and is a couple of years old I can skip the depreciation ( I hate it) I might find some poor sucker that got in over his head.
I am the kinda guy that keeps cars forever. What will the
997 GT3 be like in lets say 15-20 years ( 2020-2025)
Collectable or.............. 928,944,924,912E ( I dont dare say 964 I might hurt alot of feelings) woops I alredy said it.

I have a hanging suspicion that there is more difference between a modern Porsche track motor and a street motor than just where the engine oil reservoir is located.

Of course there is, nvertheless the most obvious and easily identifiable external feature identifing the 2 different water cooleed engines is the external oil tank used w/ the dry sump sytem.

As I said the dry sump block is a 964 casting

here is one of the internal(expensive features, Ti GT3 conrods



Another very expensive GT3Cup component


The downside of a '99 GT3Cup, later versions are more sophisticated versions oof the same basic units


You wouldn't believe whta even this simple little air jack probe costs

[KobaltBlau]

Bill, are the rear swaybar endlinks adjustable (in length, to remove preload) on that cup, and do the multilink bushings still have some rubber in them?

Thanks in Advance.

[speeder]

Please explain *airjacks*, ie. what are they again?? TIA.

[Bill Verburg]

Most of the Cup cars going back to 993Cup and even some 964 Cups had air jacks.

Sways are adjustable, leter versions are more so

I believe ruf is making the car named the rt12, based on the 997. They offer it in your choice of rwd or awd, and come in 3 engine flavors, 530, 560, or 650. BTW, those are hp figures

I see, they have their own collar and lockring. for some reason I thought that collar's movement affected something else as well, but it's clear with the shot from the other side.

Thanks for all the pretty pictures, Bill!

I lot of this stuff oughta be in MOMA

[Bill Verburg]

Finally found the one I was looking for

Watercooled 996GT3R crankcase

[Tyson Schmidt]

Minkoff, if I were you, I'd wait to see what Porsche has in store to replace the 997.

A little bird told me that it will blow your socks off. He has seen the designs personally, and said it will make us early car guys go nuts. So just hold out until then if you can.

BTW, you didn't hear this from me.

[speeder]

Am I the only one who thinks that the 997 is uglier than the 996?

Actually, I like 996's looks OK if they are set up right, ie. color/wheels/interior/etc... This goes for all cars, though, in my book.

Can't stand the 997, looks like a horrible quasi-retro cowpie. Just god-awful, IMO.

no kidding!

[Jack Olsen]

Yes, you are absolutely the only one.

Actually, I was behind a 997S the other day (driven by like a 60-year-old woman?), and I kind of liked the direct rear view. I still have problems with the 997's look, but to me the 996 was much worse.

Minkoff, if you want to see both a GT2 and a couple of GT3 Cup cars up close and personal for comparison, you are not far away from my friend's race prep shop in Laguna Hills. Vision is in the midst of stripping a street GT2 for Club Racing. How much do you think this guy's bill is going to be when they are all done???

Customer GT2 being stripped down at Vision Motorsports:



Motor out of the car:



One of the Vision/Bernheim Cup cars. DNF at Daytona a few weeks back after missing a shift during the night and zinging the motor on the high side of 10K! Set 4th fastest lap in GT though, pretty impressive for a small, grassroots team without a star-studded driver line-up.



One last shot of the GT2 going on a diet:



Cruise on down, the guys are real personable, although things are hectic right now with all of the races (Grand-Am, PCA & Tribute to LeMans) all coming up within in the next 6 weeks!

I'm a fan of Vision MS, but "small" and "grassroots"?? Bernheim wrote in the POC magazine about last year's Daytona experience. They won ~$8k in prize $$ and it cost them something like $400k for the weekend. Not including the cost of the brand new GT3-RSR factory race car. Kids, don't try this at home.

Suing people been berry, berry good to him.

Don't get me wrong, I definitely live vicariously through them. His daily driver, (at last year's CFOS):

Thanks Ralph, I know Dwain and most the guys down at Vision. Dwain sets up the chassis on my race car, he is the master

I would still consider them "grassroots", the term being relative when you compare to "professional" teams like Farnbacher and Flying Lizard in Grand-Am and Job, White Lightning, etc in ALMS. They run all of the local/regional POC, PCA & NASA events but at the professional level they are just starting out and only run Daytona & Fontana. They don't run the full Grand-Am schedule like most of the well established teams. The weekend race crew is just the shop mechanics and "volunteers" who lend a hand.

Steve has deep pockets, no doubt about it, both Cup cars are his, the 993tt is his, the 935 conversion you see in the background is his, as well as a few others lurking around the shop. Those are just his Porsche "toys", you should see his house!

BTW, they ran one of the Cup cars at Daytona last year in SGS, they don't have a GT3RSR (at least not yet).

I think that is the first Bentley I've seen with a bumper sticker.
