Motorsports Monday: Porsche 911 Twin Turbo Cup Conversion

I’ve certainly been a big fan of the Porsche 911 Cup; today, it strikes me as not only one of the best deals going in racing Porsches, but perhaps the best all-around deal in the Motorsports world. The success of the 996 and 997 Cup chassis has to come close to the E30 M3 as one of the most raced and most winning German designs in history. They were so successful that they built a lot of them, making them today slightly devalued in the world of track cars. We’ve even seen full-blood, turn key factory race 911s up for auction below $50,000; simply staggering when you consider the original purchase price. Of course, also staggering are the running costs of the Cup cars; 40 hour engines are the max, and Porsche Motorsports recommends transmission refreshes as 20 hours. The costs add up; rebuilding your 996 or 997 Cup running gear will cost you between $15,000 and $30,000 – presuming nothing big is broken. Okay, so the purchase price is only the tip of the iceberg. But what if you took some of the aspects of the Cup design and incorporated them into the even faster and cheaper to run Turbo model?

Wow. The build of this car and the presentation is top notch, and my guess is that on track this car could likely keep up with the lighter normally aspirated Cup cars. The look is great; I love the 996 Cup but the 997 was leagues better in appearance, and the incorporation of the GT3 items onto the “normal” 997 Turbo gives both a unique and aggressive look. I even think that the graphics package isn’t bad. All of this goodness is available for under $100,000, too – yes, much more than a 996 or even some 997 Cups will run you. But long term I’d guess this is an easier to drive and cheaper to run alternative. Is it worth the investment? If your goal is just to go staggeringly fast on track, this car will suit. Were I thinking longer term, I still think the Cup car is probably a better “investment” and it’s what I’d choose. But boy, is this car nice to look at!

    if this is a Champion build you know it was done right….
    and the money is just about right….my guess is that it started out as an 07 997TT for that price point..
    friend of mine did something similar but with all EVOMS & a smoking BBI full exhaust…sold the car for mid- 90’sk….bought a Ford GT….

    I am a sucker for yellow headlamps. Way too much scratch for a track toy, though.
