Comparing the 968 to the 931 is like comparing apples and oranges.

From a German perspective of data on paper, the 931 is inferior in every way. Its the intangible things; the feelings and emotion inspired by the turbo that the 968 cant even begin to compare to.

Suspension
The 968 with M030 suspension is a lot less compliant over bumps and potholes and can be almost unpleasant over lesser quality roads. On smooth asphalt, the car corners like nothing I have ever experienced. The steering is sharp and you get just the right amount of feedback through the wheels. The car stays flat through the corners and if you push the limits, it has a very controllable amount of over steer. Any rough road misgivings are quickly forgotten.

The 931 on the other hand glides down the road, but almost feels too soft. The steering is also sharp and communicative, but I think the sidewall flex and tendency for body roll gives it a slightly disconnected feel.

Brakes
Both cars have great brakes. The pedal feel is very similar and easy to modulate, but having the big 4 piston Brembos on the 968 give it a distinct advantage, especially on the track.

Engine
Hands down the 968 wins in this department. Better power, better noise, just a much more refined package.
The 3.0 is silky smooth and delivers a fantastic amount of power and torque. With a K&N air filter, some easy air box modifications, and an adjustable fuel pressure regulator I have 250 HP and 220Ft/Lbs of torque.
The shortcomings of the 2.0 engine are hard to excuse when driven back to back with the 968.

That being said, with the 931 boosting around 10psi and the lighter curb weight, the performance difference is not as huge as one might expect.

Overall

The 968 is violence and sex appeal. It accelerates harder, stops harder, corners harder. It begs to be driven to its limits, and that's what I do with it. Its a killer on the autocross course, and is right at home running laps on a circuit. Its a sexy car and garners a lot of attention from people on the street. It seems to be more of a purpose built machine. The 968 is G-forces and tire smoke; its a tool to fuel my adrenaline habit.

The 931 is just pure class and character. Its the preferred car for cruising with the wife. It an awesome grocery-getter and road trip car. If I am needing to run a short errand I grab the keys to the 931 over the 968. There is character in these cars that newer cars, even newer Porsche's don't seem to have.
The 931 is not a means to an end. Its a rewarding experience in and of itself. Its an inanimate object with enough personality to catch my attention and build a lasting relationship.
I bought a 924 when I was 15 years old; 16 years later I still have that car, and 2 other 924s. These cars have a way of getting into your soul and taking root. Maybe its sentimental, or maybe I'm crazy. There will always be room for a 924 in my garage.

Thank you for that.
I have never driven a 968 but i would like to at least drive one if not own one.
Similarily I have a 931 and a lets say more refined and potent version of the 924. And i'm happy to see that the words you type describe thoughts that i have as well when comparing the 931 to its newer more refined offsprings.

I do warn you that if you improve your 931 on those points you find it shortcoming it may change the way you look at that 968.
My 931 has been lowered and stiffened just a tiny bit and now has a perfect balance of confort and crisp cornering.
Do a spark dizzy recurve and the car will deliver power in an even more rewarding way.
I'm getting more and more addicted to my 931 with each time i drive it.

Hehe, i disagree on most of that. I see the 968 as a comfy cruiser with a pretty boring engine, more fun than the s2 though. A good car though and they can be made into really fast cars. But for raw driving experience on track and twisties my 931 is way better then any more modern transaxle car I've tested, incl racing cars. Just don't drive around with 40 year old suspension bits, shite tyres and derated us spec boost .

Were talking stock vs stock here.

Unless you've driven a M030 or club sport 968 were not making the same comparison.

I would like to hear what is so boring about 236hp and 225 lb/ft torque? 0-60 mph in 5.6 seconds.
Your telling me our noisy van motors are more exciting? I guess if valve train noise is your thing...
Even if it is boosted, the 931 is still down 25% on power and 18% torque.

Kenodog is spot on with the analysis, im not chasing numbers, except lap time . But I'm after the most fun I can get, and no car north of the lotus Elise has given me any better fun factor than my car. So thats why i still have it after all these years. I could swap for a 968 or 996 tomorrow if i wanted to, but they are just not as fun. I admit though the 996 gt3 mk1 is a really good car, but not att all worth the cash they are going for today.

What is stock anyway, both a m030 968 and 931 will have suspension bits so old that its already far from how it left the factory. So will need new stuff anyway.

Cedric has uprated suspension on his 931 and Kenodog barely remembers how it is to drive a 931
The M030 package suspension on the 968 is stiffer than the stock 931.
So unless you refresh the 931 suspension with bushings, stiffer springs and shocks it will be softer. But if you do, the 931 is just better.

Enginewise i think there are a couple of us who are nostalgic on the old iron lump and its rawness.
I prefer it too compared to a smooth modern booring machine, be it a 250hp NA, the 2L boosted has more perk more character.


But if there is win to the 2L it must be this: I recently took a hottie girl-friend for a ride in my 931 and she was juicy excited about the sound and feel of the 931.
She has been in other modern cars and she is an experienced horse rider.
She literally begs for more 931 like daily since then, i dont know how to get rid of her as i'm sure its just the 931 she craves.

I'm getting the distinct impression you guys have not actually driven a 968, or a bone stock 931.

I agree, crank the boost, lower and stiffer suspension, and even some weight reduction and your going to have a hell of a good time in a 931. No dout better then a stock 968.
However
Morghen asked for me to compare driving my cars, which are for the most part "Stock"
The turbo has all brand new rebuilt suspension and its quite soft compared to the 968. Couple that with less road holding, slower acceleration, a less exotic sound, less brakes, and you have one heck of a cruiser, but not as exciting as the 968.

You guys are more then welcome to experience the difference yourselves.
If anyone is in the Central NY area, let me know. I'd be willing to let you take both cars for a spin and see what you think.

And Morghen, my best advice to you is steer clear of those horse women. They are a different kind of crazy

As much as I want to get into the previous discussion....my seat time includes a 944 S2 stock and a stock 944 Turbo but no 968. However I felt the spirit of the 931 in these cars...anyway

'82 931 is running and driving! Its been fun to say the least but an issue developed (a misfire) that took a bit to figure out.

Turns out a washer was floating around in the distributor but we are back up and driving.

No smoke at all and just the normal intoxicating smell of a 931

Now I am developing an opinion of the 82 compared to my 80 that has not been driven since the last millennium. However my entire 931 experience is in that 80 and I loved it. The 82 is fun because I missed driving these cars but I miss my 80 in the way the boost comes in, aka the power.

I have been driving a lot of different transaxle cars, so no lack of trying around. Including some race cars, and a bone stock super low milage 931, not driven any us model though, and don't really feel the need to

I had a chance to drive pretty much any Porsche that was made for the street and modern Porsche race cars like 996 Cup and 997 Cup.

I am working on those cars for over 10 years now and have my own shop specializing in Porsche cars for about 5 years now. I used to drive daily 1978 911 SC , 1986 944 Turbo, 2000 911.
I raced for few years replica of BRE Datsun 510 that i build from scratch.

I had few 944 ,924 and 911 Porsches.
Currently have 1976 924, 1980 931 and 1986 944 Turbo track car.

I like 968. It is really refined car, I hate the way 928 feels. 968 is faster and have tons of torque ,but just does not have purity and lightness of early transaxle cars.
My fvourite is still 924... I know it is crazy but car just feels light, feels right and it is slowest from the bunch it is most fun in my opinion....

I have a customer who has more then few Porsches, He just sold his backdated 3.2 Carrera track car in favor of mildly build 924 S that we did bunch of work on.

With my 951 I can easily be fastest guy in experienced group in PCA events killing all 997 cars...but 924 has my hart and is growing roots in it as said before.

My current vintage race car project is #86 BF Goodridge 931 GTR replica, hopefully I can do some testing next year !

Had half a day to kill so I thought I would tackle the 944Only firewall brace. It sucked. Badly. Well let me restate that, the actual part itself is well made but there are a few things that could definitely be done better with both the manufacture and the install. Number one, it is plain stupid that you are expected to just screw the bolts into 1/8" of material and that will hold it. 1/8" depth of thread is NOT going to stand flexing for long before they either strip or deform. They are not even fine pitch threads which means you might get 1 full thread into the material but that is it.I installed the brace using just these threads in the part itself but tomorrow, once the urathane has cured, I will be removing the screws one by one and drilling through the plate so I can use a nut AND bolt to fasten the whole mess TIGHT. I get that it was probably designed so it can be installed by one person but it is retarded.

The other thing is the location of the holes you need to drill. They suck. It's not 944Only's fault, they need to be where they are, but they still really, really suck. I have the car stripped. There is nothing under the dash at all, not even a single strand of wire, nothing. And...it still sucked. This is because you are expected to start and then turn bolts with either a socket, wrench or Allen key. We return now full circle to the through hole idea where you would only need to push the bolt through the hole and then put a wrench. socket or Allen key on it while a buddy spins the nut on in the engine compartment. Way, way easier.

Here is the finished install :




I also got some of the Thermo-Tec self adhesive high temp matting and cut out sections to cover the body and frame near the turbo. This will be covered again by Thermo-Tec`s louvered aluminum heat shielding. I am very impressed with both products, the quality seems excellent.




Next up is to finish installing the sound proofing inside the cabin and the install the wiring harness....
