993tt

Hi

anyone installed the Turbo S kit (450Hp)?

I'm thinking of ordering it from Carnewal but I'd like to hear from you guys if you have any experience of it. Pros, cons!?

So, why not go for eftermarket stuff you say!? Well... one word - resale value! (erm... that's two words, dude...)

The kit: http://user.online.be/gcar/cpx_p93029.htm

Just what I was thinking...right after the suspension gets ROW springs. (in the works right now).

I haven't fitted this myself but am very interested in doing so in the future, if and when you go ahead with it please let us know what the difference is like in performance etc. Can it be fitted by a competent home mechanic or is it a specialist job? What are Carnewal like to deal with?

thanks

I surely will! though I was hoping someone else would give me som info before I go ahead

As far as I can tell and have heard, anyone with some skill can intall the kit. It contains three main parts - new turbos (GT2), additional oil cooler and a new ECU.
If you have immobilizer you have to let an authorized porsche dealer 'program' the new ECU, otherwise you will not be able to start the engine after switching ECU.[/LIST]

Does the immobilizer have to be 'programmed' into the new ECU? After the new remap? I am confused. I really dislike the immobilizer. JMO ->it's a serious PIA.

Carnewal is owned and operated by Gert - a long-time, well-respected poster on Rennlist. His reputation and customer service are second to none.

Thanks for for all the replies, I am reading each one. I plan to use the suspusion set up I have, at least until I find out what it is. The car has been lowered. Likely has ROW springs.. Why improve the car when the driver has not matched the car's capabilities?

It has 46K miles and I intend to use it to the max.. I do not believe in "garage queens"

I have done 3 years of DE's but never have been very agressive, i.e. never scared an instructor :-) That will have to change.

Here is what I was thinkging for the "stage 1"

GT3 seats, Roll bar, 6-point harness, 3-spoke 996 steering wheel, and front "fog light brake vent" 993 turbo S style. Brake pads when I am heading to the track.

Not programmed INTO. The new ECU have to be programmed so it matches the other electronics in the car (in some way, don't ask me how) I find this very logical, otherwise anyone could get a stolen car to start just by switching ECU.

jessejames

...and then the ECU is 'mapped' diffently than factory? for more performance/HP?

993tt

Ehrrm... well, let's see... No!

It's no difference between non-immobilizer and immobilizer equiped cars. They are all the same HP. The only thing that differs is a little 'thing' inside the ECU that 'communicates' with the rest of the car and the key. If the ECU for some reason decides that it doesn't recognise the key or something else in the car (I cannot say what other electronic it looks for) then the engine won't start - Anti-theft protection.

I have a factory power/torque diagram of the 450hp kit v's standard 408hp (unfortunately its at work, and I'm off for 2 weeks) From memory it is a cr@p set of curves, with the torque being severely limited and the top end being held down then taking off @ 6000rpm to put on 30 hp by 6800 rpm. (good memory heh ?)
You really should consider one of the aftermarket tuners, you're in Europe right ? Try Carpraphic, FVD, RS Tuning, Gemballa. They all do kits which are by now well proven and if you are prepared to change the turbos (which you will have to with the Porsche kit) then you will get more like 480hp. The only way it will affect your resale is if you make an issue of it.

I installed the kit a few months back. In addition, I installed the S oil cooler. Complete bolt in. No reprogramming at all...
It is singularly the most impressive modification I have ever made - and ALL with factory parts!

TB993tt:
When can you please send me the diagram when you get back to work? I find it very strange if the thing you say are correct. I've heard from a couple of people that have done the upgrade and all of them are very satisfied.

Stuart Zeh:
Do you have Immobilizer in your car?

TB993tt

I will send you the diagram, but it won't be for a couple of weeks. I'm sure the S kit feels impressive when compared to the stock car. I've not been in a 993tt with the S kit, but from the diagram, I would imagine the power takes off again quite violently from 5800 to the red line, again from memory the S kit puts on 30hp in 1000 rpm, this will give good seat of the pants thrust. I also have some acceleration figures taken from a UK model 450ps turbo S. From memory, the car did 0-100mph in 8.6 seconds - pretty impressive. My main point is that for what you are spending and doing (ie having to change the turbos) there are better value and more impressive kits out there in Europe. And personally (in the UK anyway) I don't see the issue about non factory parts affecting resale.

...But there IS a reason that Porsche parts should be preferred.. Porsche R&D should be preferred over the basic "tuner" "guess and build." Resale is the least of my concern - but I will personally not buy anything with aftermarket parts...


BTW, my car has the normal Drive Block from Porsche...
