Greetings,

I'm thinking of purchasing a low KM '07 C4 Turbo - super clean, all docs, no mods except rims and exhaust.

I currently own an '05 Boxster S that I put a TPC Stage 2 Turbo in along with Fabspeed headers. From a performance perspective it's pretty tapped out and even though it was a massive improvement over stock, the best part of the car is the handling.

I've always wanted a 997 Turbo but I know that it's not going to handle like that little Boxster S. My question to those far more knowledgable than I, are there suspension mods that I can make that will bring that 997 more inline with that Boxster S?

Thanks in advance!

Some creative searching has led me to this thread:

This has been a great resource but if anyone has an opinion on the type of suspension that would give me the same type of performance and feel as that Boxster S, I would appreciate it.

Lots of good info in that thread ,you'll love the turbo's power & btw the Turbo is not a C4 thats one of the Carrera models.

 

So is this a 2007 911 C4 with an aftermarket turbo kit? Or it is actually a 911 Turbo?

 

Supension is not the big problem... I own also a 997.1TT and a 987.2 spyder PDK.

The real different is the big heavy Mezger block in the back. There is a difference about 350kg of weigth. The 987 handles much better in winding roads by far. Even a poor stock 991S PDK will let you no chance on the road in 997.1TT sixspeed. The 997TT is build for the US market or german Autobahn driver. Heavy and made for comfort. A 997 GT3 may will be the only choice to get rid of your problem.

Thanks to everyone for their replies, I appreciate the advice. The car is a '07 Carrera Four Turbo Coupe with 49,000Km.

From what I've read, this car has the first gen PASM which is soft in 'regular' mode and too stiff in 'sport' mode. I truly love the way my '05 Boxster S handles with the extra power that the TPC Turbo provides. If there isn't a lot I can do to address the difference in handling without dropping loads of cash then I might let this pass by the wayside.

I've also found a few GT3's in the same price range and have been told that the handling is probably closer to what I'm hoping for. I need to have a little more room in the car than the GT3 will provide (the car I buy will be more DD than track though I'd like the track option).

I won't pretend to know a whole lot about these types of mods - the TPC Turbo and Fabspeed headers in my Boxster S were my first and I was very, very please with them but I'd like to upgrade in the raw power department and hopefully keep that 'handles like it's on rails' feel.

 

Ok i'm still confused & apparently so are you ,is it a 911 Turbo model or a Carrera C4 model with an aftermarket turbo kit ,it makes a huge difference there is no such thing as a C4 Turbo model it's one or the other.

 

You, me and the dealer apparently.....

Uh, no only you and your dealer were confused. That is a 2007 (997.1) Porsche 911 Turbo.


Anyway congrats on an awesome car.

 

Thanks for the keeping it straight.

Sooo..... with the 997.1. is the simple fact that the car is heavier and that the weight is distributed where it is - that it will always be a different kind of beast, regardless of the type of suspension mods made (as yah996 points out) or can I achieve some sort of happy medium with some modifications?

Talk to TPC Racing for their suspension package for the turbo. I had my engine and suspension work done there. I basically put the GT2RS suspension geometry on my turbo (longer wheel base, 2" wider front track, toe bars, anti-roll bars, agrresive alignment and bunch of other suspension parts), a custom packed GT3 Limited Slip Differential, TPC's DSC module (Dynamic Suspension Module), lightened the car about 200lbs. I run Pilot Super Sport tires.

At the end of the day the car is brutally fast, but it is a 911 and the handling characteristics are very very different than the Cayman. Do yourself a favor and see if you can drive a turbo on the track as the car was just not designed for the track and to get it to be a good track car (e.g., the work that I got done to my car) requires a lot of money and patience. My car's weak point now are the brakes!

If you are track inclined get a GT3, but the power is limited. If you do more street running and like the acceleration a modified turbo is preferable. I wanted both and spent a lot of cash to get a turbo that is fun on the street and the track. Though it's still more of a street car than a track car, specially since I don't have a cage/roll-bar in there. Given the speeds that this car gets to on the track I really should put a cage/roll-bar in there, which will make it even less streetable.

Good luck with your choice.

 

Absolutely you can.


I wanted a multi-disciplinary car that would be great at both straight line (Airstrip) racing, road racing, and yet be comfortable enough to do long distance type stuff (think Gumball/Bull Run).


I went to BBi Autosport, which is owned by guys who race and worked for Porsche racing teams. Many of their clients want the same thing out of their cars. When I was having my suspension done (Ohlins R&T, rear end-links and LCAs), Tanner Foust's personal 996 Turbo daily driver was there having some custom work done to his KW Clubsports to make them more comfortable. Give BBi a call and they will steer you in the right direction for your needs.

 

Once again, the board community comes through. Everyone's advice has been very useful and Cannga's thread on his experience with suspension tuning has been very educational.

We're a little limited in terms of tuning choices where I live (Riegel Tuning is well respected for Porsche - they did my TPC install on the Boxster S) so anything I decide to do if I make a move on the car may be limited to local install expertise.

At the moment, it looks like the general consensus is coilovers, sway bars and perhaps an ECU tune would be the best places to start.

Thanks again for all the advice and model corrections.

Today, I purchased one of my dream cars - a 997.1 Turbo - and after spending some quality time with it, I'm having a hard time wiping the grin off my face.

I just wanted to say thanks again for all the advice and information, it allowed me to make an informed decision on the purchase. I knew what to expect and appreciated it for the beast that it is and not come away disappointed because it didn't feel as 'sharp' as my turbo'd '05 Boxster S. Now, it's 0 - Apocalypse in under 4 seconds

Now, to ECU or not to ECU, that is the question.....

Read, read and more reading.

 

Yeah I was about to say, drive it first then decide if you NEED a new suspension setup straightaway. I think a lot of guys run out and get one just because they read about it, without understanding what its bringing. yes we all know it "handles better" but how? most people cant answer that because when I do a suspension I do it for how i am driving or the course I am on. See if we always Apexed it... we woulf be getting paid to drive. Little slower and late usually keeps you out of the tire wall
