I've put the questions out on both forums (996 n/a and 996 turbo) as to which way to go.

Each board says go with their car (not surprising), but I have noticed a few things. The turbo guys say their engines, clutch, etc. seem to last much longer than a regular 996 n/a car. I really am down to this: has anyone on here actually daily driven a Supercharged Carrera for several years or 10,000+ miles? If so, how did it fair for dependability and was it as fast as a stock (non X50, etc) 996 twin turbo?

I am not just asking for the heck of it. Within the end of the year I'll be pulling the trigger on this. The turbo option costs a little more (22k+ vs. about 14K+) for a same year/milage car. However it has more potential for future mods and "might" be more bulletproof at taking the power. If I don't hear anyone having driven for an extended period on the Supercharger, I'll have to upgrade to the turbo. But, if I keep mine its 200+ lbs. lighter, done with mods, faster? than a stock TT, and a sleeper. Plus, it has a convertible top! Learning (one way or the other) about how the TPS or EVOMS intercooled supercharges have worked out will help.

Any input (especially those who have had them/compared them) would help!!

Please keep in mind I'll be keeping either car for the rest of its life (probably another 10 years/150,000+ total miles) and both options have their advantages and disadvantages. Money is available for either, but I am concerned about the costs over the long haul (an engine swap at some point is ok, but two or three isn't!)

Thanks all!

Turbo, almost entirely because I'd always rather have factory engineering and factory support than being left to deal with the problems myself.

Turbo, not even a question.

I would go turbo.

The N/A motor is already at 11.3 : 1 compression, boosting it will increase cylinder pressure tremendously. There really isn't any room to increase boost without decreasing engine life at this threshold, if you will.

The other issue I see is the N/A trans struggling with holding the power for the long haul. There have been some who broke the trans N/A (probably abused), boosting will just increase stress. I have zero data, just a gut feel.

But, from what 1999Porsche911 says, he will walk a stock TT (understandable, power to weight). He and Karlooz have boosted their N/A engines without issue for many miles and track time. PM one of them, they have first hand experience.

There is no question .....TT cab

As Tippy said, the compression is too high with the NA engine to safely supercharge. The turbo is the way to go.

Thanks all. That was the way I was leaning also. I'll miss the Cabrio top (Cabs are another 15-20 grand), but the power and solid top will be a big plus. This site is great, I really appreciate it.

You will have to spend even more money in oder to to get a stock TT to have better engine performance that an SC'd 996. If you like a convertable, SC you existing car.

Read this... http://www.6speedonline.com/forums/s...d.php?t=123442 btw that 996 is a cab, there are alot of SC installs out there and there are some with over 30K miles out there. Its well designed and its only 5-6 psi boost for 450+hp...

don't tempt me dammit

I think you know the answer deep down inside here, but if you're going to FI then definitely a factory TT

1) way more tuning upside
2) stronger motor by most accounts
3) if kept factory or even just flashed it will retain more value over time

If you were looking at an SC because you're worried about turbo lag or anything like that, I'd do 997S X51 (I feel like it is faster than the spec sheet reads, and that motor SPINS, sounds great, is preferable to me over turbo, although no tuning really possible)

But another poster raised a good point. If you like a cab, a turbo cab might be a lot more money

You need to compare the cost of a SC cab and Turbo Cab to be fair. Otherwise its kink of like apples and oranges.

In addition to the SC having better perfromance than the TT, drivability around town is much better because you have higher compression ratio that you do in the Turbo. No lag and the car will drive just like it does now.

Tippy

Very true points but there is nothing like the violent, wallop, sledge-hammer-to-the-back, OMG this is craziness of a turbo

Just my .02

Yes, the N/A with a S/C should feel a little peppier around town than a TT but the WB of the TT car, mmmm........mmmm. Preatte

Jackel

Thanks again. That other thread was perfect, some SCs with over 60,000 miles on the blower, that'll work...

Just so everyone knows, I'm content with being just a little faster than a completely stock 996TT and "in the race" against faster 997TTs or C6Z06s...

If I "need" to go faster than that I'll get back on a motorcycle...

For me the SC cab and Turbo coupe is apples and oranges, but the only ones I can afford! Total cost to upgrade mine 15k, to sell mine and upgrade to a turbo Coupe (for me, I'm upside down is 25k+

To go to a Turbo Cabrio is 40k+

SO, apples to apples is price. 15k one way (SC) or 25 k the other (996TT Coupe). Thanks again all, leaning back toward the SC now...
