I've had my 4S cab about 9 months. Great car and I really enjoy it, but I've got an itch for more power. I haven't driven a TT, but from what I've read it sounds like it will certainly satisfy my itch for power. I'd love to get some insight from any owners who've done the jump.

I'll post this on the turbo board too.

I have both. In winter the C4S is much easier and safer to drive. Actually a lot more fun because you can hammer the throttle around and it just sticks. It also gets better gas mileage when driving it hard where with the TT it's a pig even when taking it easy. The C4S is 100 lbs lighter then the TT.
When it comes to the clutch, engine and power they are completely different cars. Handling is pretty similar.

My switch was from a 996 C4S coupe to a 997 TT cabriolet, so there are more differences than just going to a turbo. That being said, here are my thoughts:

- The turbo has much more power, as you would expect. I live at 7,500 feet of elevation, so the difference is even more pronounced. This is one of the reasons that I was attracted to turbos.
- If you're into tuning a car for even more power then there are more options for a turbo.
- The turbo cars are the flagship in the 911 line, and they are generally very well equipped and often have many nice options installed.
- Speaking of power, there are a couple of things worth mentioning. First of all, the turbos do suffer from some lag issues. It's manageable, but the power delivery isn't as linear as a normally aspirated car. Secondly, you get used to it. My turbo felt so fast that it should be illegal when I first bought it. Now I'm used to it and it still feels fast, but it also feels more like a normal car to me.
- I'm not sure what jumper5836 means about the clutch being different. In my case, it's also very different. The turbo is actually harder to drive and I always feel like I'm going to stall it when I'm starting out. The clutch has a very small zone of engagement - it feels like it's either on or off.
- I agree on the comments about the turbo being a pig with gasoline consumption.
- The turbo doesn't sound as good as my normally aspirated C4S with Fisters did...
- I had more opportunities to run the C4S up to redline and push the engine a little bit. If I run the turbo up to redline, I very quickly end up at "arrest me" speeds. I find that this results in short bursts of acceleration when the opportunity arises, but you don't get as many opportunities.

Overall I'm very happy with my switch to a turbo. It is a very different animal and it drives very differently. I suggest that you drive a couple and then decide. I don't think it would be a bad choice to keep your C4S and I don't think upgrading to a turbo would be bad either. They are simply different.

Clutch is hydraulically assisted in the Turbos. Feels very light and it does seem harder to get rolling out of a stop in first. The C4S is heavier, engagement point feels more progressive.

while sort of the same topic...

how big is the change from 911NA to a Metzger NA 911 - GT3? is the difference significally feelable? yes there is 60hp increase on power in mk1 and 80hp increase in mk2.

since I like the mk2 gt3 look, is it worth spending all that money on it? or if the design is the main charm, then stick with the simple humble carrera, with a mk2 bodykit on it?

I mean the noticeable difference how the GT3 gets to the speed, and the handling etc?

I know it should be better, but as a daily driver? (since I have no options of driving them here (Latvia) the thing I am afraid is, whether it is not too hardcore, that would make it a garage queen)

maybe someone can share

Some good insight. Thanks. I'm not too worried about gas milage because it's not my DD. I'm more concerned about the power/speed. I don't need any more tickets. I'm usually good for one or two every couple of years. I centrally don't need a 100mph+ ticket...

I got rid of my E60 M5 after hitting 156mph once. It scared me how easily I got there. I'm sure the TT would be similar, if not even quicker. But I guess that's why we buy these cars.

Regardless, maybe I'll test drive one and then set the wheels in motion... A local P-car specialist dealer near me has one and I know they'd be open to a trade.

you spend more....on my NA...i knew no matter how much i spent....i'd get maybe 30 more hp. so i did spend a little and got somewhat close to that 30 more hp.

on the tt...you know there really is no limit with quite a few of them runnign around with over 1000hp.
you buy exhaust...tune...intercoolers....etc....then upgrade turbo....then upgrade turbo...and now you want to upgrade turbos again....

other than that no really downside.

That's my experience too. It feels like I have to give the turbo more gas from a standstill in first gear to prevent it from stalling. It has been a long time since I've had "hill anxiety" with a manual transmission, and now I'm feeling that again!

jumper5836

Just a chip/tune and the 996tt is easy pushing 480 hp and it can do that forever on stock internals.

I remembered your post a few months ago (and have seen your car listed for sale):

I say its time to GIT R DONE.

Too funny for calling me out kromdom. The search begins... It's always the best part.

kromdom

let's just say that I am living vicariously through you (yup, I have also been lusting after a turbo)

WPOZZZ

I had a 99 C2 back in 06 and it was my DD. Since then, I've been through a three 930s, a 964t and a Weissach SC. I felt the na cars were much more suited for DD duty than the turbos. Why? Because the turbos were high strung and really wanted to be opened up. I have my 996tt and have been using it as a DD for a few weeks and it is a great, but it still wants to run. That would be great, but when you're stuck in traffic, it gets really frustrating!

Now, I'm looking at a C2 cab that I can use as a semi DD along with my suv.

I'd like to add a few comments to Dennis's post
Correct, virtually limitless...I enjoyed personalizing my car.
A simple tune (simple as in you can flash through the OBD port) fixes this
Replace the assisted clutch (accumulator/slave et.al.) with the GT2 clutch package and the clutch becomes very predictable and easy to drive.
Mine averages 19 mpg...not sure I'd call that a pig...LOL
This is why many opt for aftermarket exhaust...like Europipes...oh what a nice sound.
Correct...you can go fast quick. Install a decent detector and choose your "bursts" wisely (and safely). On the other hand, I can pass whenever I want to...

Turbo Porsche Carrera...the one and only!

BTW, I've had a 930 and a 911SC.

One thing I love about my 4s is that when I accelerate to 60 it feels like I'm doing 100. In my M5 I would feel like I was doing 60, but actually doing 125. Very dangerous and risky. Is that how the TT is?
