The 993 TT stopped production in 1998 (sold as S and standard 993TT in 1997) and began the water cooled versions. The last 911 air cooled turbo cars cars were up to track condition builds. Had issues with the new water cooled motors, especially in conditions where they should have fared better.
Considering the history behind the engineering of a motor that began it's life in 1938 has got to have extra ***** by 1996. Best of the breed. Google some monster 993 TT cars. Kick *** motors and awesome rides. We all have our favorite.
Doesn't matter. Love these cars. Just have a keen interest in the battered 951 and it's feeling behind the wheel of a well set up car.

Jeff,
I'm not supposed to be up this late, but we have to plan our trip to Greer. I'll send out the offer to Jeff, Jeremy, and some other folks via personal e-mail.
Your car looks awesome.
George

Right, I was pointing out that you said air cooled AWD, there is only one generation and that is the 993TT

I took out the AWD parts to save a little weight, but more importantly, to restore handling to "conventional" 911 behavior.
Because there is no center diff on the 993TT--it uses a viscous coupling instead--there is practically no torque sent to the front wheels during normal driving. But when there is a difference in speed between front and rear diffs (i.e., wheelspin at the rear), the viscous coupling starts sending torque up front.
What this means for the driver is a delay between when oversteer starts and when the front diff starts doing some work. As a result of this there is a "mid-corner wiggle" and correction required because often your line will change when the front diff starts working.
At stock horsepower and torque levels, you barely notice it, and the factory AWD works pretty well to keep you pointed in the right direction. Unfortunately, when you add horsepower to these cars (I have bigger turbos, exhaust, and ECU tuning) the AWD wiggle becomes more pronounced and more distracting. It also results in understeer in tighter corners.
Long story short: I prefer 911 handling without AWD "assistance." I also live in Southern California and NEVER drive the car in the rain. But it's still somewhat controversial. There is a fairly large contingent 993TT owners who have done the same, but the other half of the community thinks the 2WD guys are a bunch of heretics destined to crash into a wall ***-first.

Thanks, George. Can't wait to see your car in its finished state--sounds like a real beast!

Can't wait to get this car to the track. I'm going to Tucson Int. Dragway in a few weeks for their test and tune. My local tuner will help me get the TEC GT and boost controller dialed in. You simply can't do this on any street with a steady heart beat. I'll post the 1/4 times. I don't clutch dump, but we'll get a good idea of how the car is performing from the trap speeds.
Regards,
George

Curious for some real driving action around here.
My favorite 951 show Has apparently been canceled... Tool.

Don't confuse the motor of a 996 Turbo with a 996 N/A.

The next test and tune here at Tucson International Dragway is this Friday, and I'll be in Phoenix with clients that evening. Next one is in August on a Wednesday evening. I'll probably get to that one or head out to Firebird in Phoenix. I still have to calibrate my Innovate AF guage. It reads richer than actual tail pipe readings. I want to match the 02 to the tail pipe readings. From there, there is some fine tuning to do with the TEC GT.

Jeff may be nutty, but the 1997 S model was RWD with only a few more HP and TQ. Must be a reason that the best factory car deleted the AWD.
RWD cars with good suspension on tar roads sans water and snow don't need AWD if you are using the car as designed. That up front pull when you are just getting the tail out in a corner would be surprising to even the best drivers with knowledge driving these cars.
Who really cares. We are car guys and like what we like. We'll switch cars for a drive after he sees my *** on the way to Greer this fall. LOL

The 993GT2 (both racing and street versions, the latter never being sold in the US) were RWD only.
