C2 Turbo

Thinking about expanding my search and including 996 TTS as well.. Well the more i read about it the more i get confused... So far i have gathered the following info on this particular model and please feel free to correct me
a)- It has the same turbo K24 as the X50 but does it really makes 489 HP as
GT2 ? I was told TTS has the same power but is AWD ? Different sources say different stuff so what's right,heck who knows ?
b)- Suspension,is stance slightly lowered than the stock X50 ?
c)- PCCB is standard while it was an option in an X50 ..
d)- Guages could be different ?

So why the heck is TTS so expensive ? If one can afford it,is it worth the money ?

Please advice..

a) It does have the same K24 turbo, but depending on the year it might only make 460 hp or so. The K24's are laggier than the normal K16s, but when you tune may have a slightly higher top end potential. The limiting factor for all the 996 turbos, however, is the fuel system. Without upgrading the Fuel Pressure Regulator (FPR) or the fuel injectors, you'll be limited to around 490 hp with a tune whether you go X50 or not.
b) The suspension is the same as the stock turbo.
c) nearly every X50 I've seen has PCCB but these were all Turbo S models.
d) not sure

I went through the same vetting process. I think, basically, anyone who doesnt want to touch their car would rather go with an X50 because of higher top end power. If you plan on tuning your car and adding an exhaust, your results will be the same. You can upgrade your turbos to K24s for about 2500 (plus labor) and upgrade your intercoolers way beyond the X50 ones by retrofitting the 997.2 turbo ICs to a 996. That would be about 3500 + labor for the upgrade. PCCB's cost another $5-10k on the other hand and probably aren't worth it IMHO. I went with the base 2001 Turbo.

if you intend on keeping the car stock well spend the money as it is the more up specked car.

If you intend on tuning it don't bother it is not worth the money.

The 996 Turbo S was only available in '05. Most '05 Turbos are S models and most of them Cabs.

The S models had the X50 package, PCCB brakes, silver instrument dials, full leather, and a few other trim options. The S package was basicly a bunch of nice stuff offered at a $13k savings over adding the same options to a base Turbo. The power was at 444HP, 29 more than the standard turbo. Suspension was standard turbo.

The brakes are basicly eye candy in my opinion. The standard turbo brakes will stop fine on the street and track fitted with a high friction pad. The PCCBs are overkill for the street and for the most part disliked for the track. The replacement parts prices are nutz!

996TT model range in a nutshell:

Base 996TT (01-05) K16 Turbos 415hp
X50 996TT (02-05) K24 Turbos 444hp
996TTS (05) PCCB was standard K24 Turbos 444hp

There are other details that I ommited, but basically thats the whole model range

Are we sure about the HP though ?

The factory order guide for the US '05TTS states 444HP. Other countries got a slightly higher rating.

There was a "P81 performance plus package" that was available pre-2005 that included PCCB's, X-50, SS exhaust tips, thicker steering wheel, and Sport Techno wheels for about $29K. May explain some of the PCCB + X50 combo's.

The X-50 is especially worth it w/ a tip. Tuning a tip involves addressing the safeties in the tiptronic software designed to protect it from too much power-even with the X-50's "transmission reinforcement". Not a plug and play tune like a 6-speed.

The best part of the X-50 is long gone-complete factory warranty coverage for that extra power.

This.

The "S" is simply a standard set of options bolted onto a 996TT. Porsche tended to do that at the end of a model's run to bulk up sales as the model was ending to help sales.

An X50 and an S are the same in terms of performance.

And if you change the exhaust and do a flash, the HP gain with either k16 or k24s dwarf the differences between them in stock trims.

Why do they cost more? Porsche knows what they are doing, and the moniker DOES help create a level of exclusivity. We can argue if it really is or is not exclusive, or if it matters, but it is there.

The 444 is a DIN (German) rating. The SAE (U.S.) rating is higher because of the way the calculations are done.

MR DUCE
Are you saying that the X-50 tip trans is not the same as the standard tip trans?

adam_

^^If he is, he is wrong.

BostonDuce

It may or may not be the same internally.

As part of the X-50 package, Porsche claimed "reinforcement" to the transmission.

If you want to tear apart a tip to verify, I'm perfectly willing to let you guys go first and report back.

I was aware of this reported for the 6speed manual, but not the tip. Do you have a source???


For the manual, there was one marketing piece, generated by the US arm, that made a comment about the transmission being 'reinforced'. This has been the source of perpetual rumor that Mr. Duce cites. One throw away line in a pre-production puff piece, and an enduring rumor...

But subsequently this has been debunked by the lack of any difference in part numbers between the tranny in an x50 and the tranny in the regular TT..same exact part numbers.

There continue to be sporadic rumors about 'one off' differences internally with steel synchros versus brass, but again no PET part number support.

Craig's post has a link to the US Porsche web site at the time about the transmission difference. Unfortunately the link now points to a current page, but he was kind enough to provide the quote.

The '04 Tequipmment guide stated the same about the transmissions. The X50 option was detailed over a few pages with an awesome photo of a red-hot turbo for those who couldn't read.

But I'm sure you're right. Since there seems to be no proof in PET about different internal part numbers it was probably just embellishment by the factory MadMen. In the Tequipment catalog, and on their web site.

Back in the day, for the 6-speed at least, there were three part numbers in the bunk;

xxxxxx 010 50 =TT
xxxxxx 010 55= TTS/X50
xxxxxx 020 88= GT2

Those three part numbers caused much debate in '04-'05 on just what the difference was. Could be a different color bratwurst they consumed at lunch when they were writing the specs for the X50. Nobody was wiling to tear down their tranny in search of the truth. The factory, as usual, just winked. It made for good theater.

Never have been able to confirm different part number on the tip, but it wouldn't surprise me if the factory did something during production, and when they ran out of parts said
"Auf Wiedersehen". No big debate on the alleged miracle differences in the tip that I can remember. But tips are mostly seen in cabs, and those people would rather shop at Ferragamo than FVD. Performance just isn't their bag.
