Is this seller of this custom 911 on ebay for real? Claims 0-60 in mid 3's???

 

Probably - I'd guess he'd take the just-under $50k reserve for the car.

And 0-60 in 3 seconds or so is not remarkable for a heavily modified car, particularly not a Porsche, which even if only 2 wheel drive, has so much weight on the rear axle. that's about what new Turbo models do. Many heavily modded street cars car to 0 - 60 in under 3 seconds (e.g., my Camaro, see signature), at its best it does it in about 2.8 seconds (lifted the front end as it does).

The price is right, though. Note this is not a factory turbo model, nor an aftermarket "tuner" car from someone like RUF, but a standard 911 modified by a local, though experienced shop using standard performance parts, etc. A person can have a lot of fun with such cars having them modified, etc., but they retain very little of the money you put into them.

I speak from experieince all around, particularly with my current 'vette.

Cars like this tend to be fast, but a bit unbalanced and unfinished, and to give many minor and maybe some major headaches. The tune (engine computer re-programming) is seldom perfect: everyone gets the re-tuning right at full throttle, but few spend the time and money to re-tune it for allother situations: cold idle, warm idle, hot idle, partial throttle in traffic when cold, when warm, when warming up, etc. As a result the cars tend to have some driveability problems randomly.
Then there are sometimes chronic durability problems: the owner didn't pay to replace key parts just to make them stronger, but spent only on go-fast goodies, or sufficiently durable parts were not available. Or some of the go-fast parts usedhave their own problems (a popular aftermarket SCr kit tends to warp its frame and then throw belts ad infinitum, until you figure it out).
When you or your shop go to do repairs, there are "what part do we use?" issues -- you have the car half apart, and its obvious that the throppet bearing push lever is not stock, but where did it come from: a different Porsche model? Aftermarket? Another brand. As an example, a popular upgrade for one model Maserati is to switch the clutch out for one from a Chevy truck. If you don't know these little tiny details, and no one but the guy who did the mods does, you're screwed.

So, these cars are fun, but frustrating, unless, like me you pour money in to them to do everything correctly: the "tune" on my 'vette's engine computer cost nearly $5000 and took a full month, with the mechanic driving it to and from work every day with a data logger on it. There were a hundred minor issues and each seemed to cost between $500 and $1500. In the end I spent as much money as if I had simply gone to a good tuner company (Lingenfelter in the 'vettes case, Ruf in the Porsches case) and given them the $$$$ they for one of their "standard" upgraded models and told them 'call me when its ready."

 

I think we need to ask John Force... yee haw
