An invite to mr. Special Tool, I would like to see your car in person. Join up on the fall foliage run organised by another 944 guy. No racing just some fun porsche driving. Or is it stuck to the dyno?

I would think that due to its design that it must have some pretty good bottom-end torque. For a 4 banger that is...

My 89 944S2 is a 16 valve 3 liter 4 cylinder. The S2's only produced 208 hp but I have to admit although it is slower than the 951 off the line it moves along nicely once in the revs. Low end torque is far better than the 951's "stock" that is why I chose it instead. Very easy to drive and great for autocross and DE costing relatively nothing in comparison to the 928. The 968 is better but entrance fee is double or more and now we start getting into 964 pricing which I would prefer. Although the 944 is a lot of fun the 911 is a much more solid and challenging car to drive.

Yes thats true and basically I would discount it only because that engine is the 968's predecessor, and in 92 they went to a 4 valve head and a variocam, which increased the hp to 236, and into the 968 it went. We know porsche was actively playing with the concept I was just curious if any other modern manuf. were.

.....I have to admit that although slower than a 951 off the line it moves along nicely once in the revs

Yeah, they're cool cars alright, I got a chance to drive a 968 cab today from a friend who works at a dealership. I have to admit it was a great deal of fun. The engine has lots of torque. But alas I love my 928 too much and I'm not really a cabrio sort of guy. A sunroof's good enough for me.

Sep 30, I am in worcester which is right up the road from you relatively speaking (i know ct. and drive thru quite often). You can meet up with me and continue north. Bring others if they know how to ride responsibly. Be nice to see some cool 951's etc.

You're right, Heinrich. The stock 968 and my stock 928.....the 928 outperforms it every time. However, according to the link in the previous post, a turbo 968 is about equal to the 928 GTS...except in weight...which makes a considerable difference. Therefore, a turboed 968 should be a screamer....on the other hand, the complexity of transforming the 968 into a turbo is MUCH more difficult (and more expensive), and thereby (it seems to me) to be the better investment to force air into the 928...cheaper car to begin with...cheaper mod...and more performance. At least that's what I seem to be hearing.

I have a freind that has a turbo 968. His car uses many factory parts and is a 968 turbo S cloan although he is producing over 400 hp. It is a fantastic, very fast car and looks good too. I don't know how much he spent to convert it but it was not cheap but worth the money. IMO I would rather have his car than a modifed 951.

Harv there are great Internet writeups from people who have turbocharged a 968. Remeber .. it will be expensive, BUT it will be a better investment. Easier, cheaper, just as fun is supercharging the 928, but it leaves you with incrementally very little value for resale.

Silly Glen, the displacment of those two crumpets could NEVER approach the massive displacement of a pancake ..... and the cost/benefit or displacement/weight are not even close! Look how heavy they are, that bunny must be a real pig.

You have to remember that the 968 Turbo s was running with restrictor plates to keep the Boost @ 1bar. In the same way, the 951 was never allowed to run any higher than 11lbs of boost. You have to wonder, why? I am running 19 psi daily withouth any internal mods and 22 psi for special occasions I have been running the same setup for almost 3 years without any blown head gaskets, broken trannies yes, but no blown head gaskets.

Now, to put this into perspective, my car's weight with 1/2 tank of gas is approx. 2790+/-lbs. At 19psi, the power output is 341rwhp & 349rwtq. If I raise the boost to 22psi I get 380rwhp and 401rwtq. You have to see the expression in the faces of unsuspected C5 Z06's drivers when I make them look like if they are going in reverse.

Waste of $ would be a more appropriate way to put it Your not going to get the $ spent back that you put into a mod like this, imo. So pick whichever model you would most like to zoom around in as opposed to which is the best investment.

What did you do to drop the 210 pounds? My 911 turbo is 3120 pounds and is running 430 hp with 450 pd-ft of torque and I leave C5 zo6s in the dust so it is not a major accomplishment. I also have no problems with vipers and most other cars I come accross.

I do know that most of the higher powered 951's and 968's I am aware of have clutch and tranny problems not to mention broken axles.
