i keep having this debate with myself 
as i see it there are three options for generating real power.
1. a twin turbo conversion. i've read about the protomotive $10k stage 1 solution which seams like a deal for 400 hp. although everytime i talk to someone about it they say $25k.
2. the collins solution which seams to generate 325-350 rwhp. outstanding and you get a new motor with it. but the cost is approx $10k for the kit and probably $8k to install.
3. the supercharger systems. pricing for the kit - $7k. Installs seem to go for anywhere from $2k to $10k and many complain about the customer support. i personally don't like the 7th injector in the airflow either.
so my conclusion is if my motor goes out i'm doing #2. If i could get a seious amount of power for $7k-$10k installed i would do it. I also believe options 1 & 3 depreciate your car.
Cheers,
Boris

Thanks for your time

Damn. I just reloaded the website, rather than use my "favorites" button, and sure enough, Todd has relocated to Arkansas. Fortunately, S Car Go is located close to my home town. Looks like, when all the funds are available, they will be doing the work.
Thanks for the heads up David.

Wouldn't the thing to do is find beat 993 (engine wise) and pay in the low $30's for it- add the Promotive Stage 1 for $25k (which is it - $10k or $25k??) and you're well below a 993TT?
Mind you, you don't end up with a 993TT but it would be a pretty sporting car with 400hp.

there was a write up recently (6-12months) in one of the 911 mags covering a nice turbo conversion - driving impressions, technical aspects etc. I can't recall if it was Promotive or not, but believe so. I'll see if I can find the article when i get home in case its of use to you.

If you are interested about cars that have had this done try calling Jason at RS Enterprises in Ventura, CA or Tim at Mind Over Motorsports in San Diego. Jason is the shop owner and has installed turbos on his own 96 C2. I also remember seeing a customer's 993 NB with twin turbos at Mind Over Motorsports in San Diego that I think they did the mods to themselves. Interesting that both shop owners have 993s of their own. Says alot about these cars....
