What is the technical differences between a 993TT and 993TTS

[inkyboy360]

So lets just say I had a standard 993 Turbo 4 and wanted it to have standard ride but a TurboS spec engine/mechanicals and exterior, whats the differences:

I know about-

1. Aerokit II spoilers
2. Yellow brakes
3. Carbon interior
4. Rear Arch Scoops
5. Front bumper vents with integrated lights

What else came with the car and makes up it's DNA?

Please explain the above also if I got any incorrect,

thanks
Paul

The engine internals are the same but RoW versions had K24 turbos, an extra oil cooler and a different ECU for 450 hp rather than 408. US versions just had the extra oil cooler and different ECU for 430 hp.

The suspension is somewhat different as well. More knowledgeable folks may well step in; I would describe it as a partial GT2 suspension with different front uprights (for less bump steer) and stiffer springs and dampeners. I think the track rods were different as well for less compliance as other bits probably were as well. I think people generally found it rather harsh for street use.

Basically, you can upgrade the standard 993tt with the Porsche Power Kit Plus (at least I think it's called that). That includes new K24 turbos, auxilliary oil cooler, new ECU and the quad tip pipes. It's commonly thought that the quad tip pipes are purely cosmetic but that's not true. The muffler boxes have have their end tubes cut back to fit these. They have a slightly wider connecting pipe to allow a little more flow.

I had the kit installed on my turbo just under a year ago. It's well worth it.

"what makes up its DNA" is a great question and I would have to say that the suspension package on the (Euro) 993 turbo S was what really differentiated the car from the regular tt.

The "S" suspension was developed by Weissach and offered in kit form as a retrofit for £7800 back in the late 90s.

I have the full kit on my tt and it is very comprehensive including all new aluminium links and arms etc with firmer bushings, solid top mounts etc etc.
As has been said on here it made for a very choppy ride in the UK. But...... with a set of PSS9s to replace the "S" spec shocks and springs, the harshness disappears and you are left with a superbly tight yet compliant chassis in the 993. I run a decent amount of torque through it and the car it totally composed.

The part # is 000 044 500 02 - Retrofit Kit

I guess they didn't sell too many since I got mine from Porsche GB for a "clearance price" of £2600 in '99 which was ridiculously cheap....

Here is the Porsche GB "blurb" on the kit:

great detail chaps, would you mind emailing me any detail you have like that pls. [e-mail]

I have recently picked up a 993 Turbo 4 from the classifieds and it has the scoops and I planned to put an Aerokit II on it as I need to do the front PU anyway, and I really like the rear spoiler from that kit. And was thinking about slightly uprating the engine/suspension and would like to keep it all Porsche OEM kit.

The car has a Full OPC history and has been loved for years so I'd rather keep it standard than do anything daft to it, but like the suspension kit and engine mods mentioned.

I have a budget of 6k to spend on it.

Any ideas on who does the Aerokit II or should I just get a replica one from Design 911 or the likes?

Cheers
