Not me Orc!! I do not think a SC is good for a 993.

Go for it
Proto Sport, in Pompton Plains, NJ, does a good job of converting NA 993s to TTs. They have done a car that runs very well in our Region and Metro Region DEs. 973-839-5353, talk to Paul.

Why not just get a turbo and remove the front drive shafts like Viper Bob does?

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

Question

Boris,

What is the Collins solution and why not add a 9M engine heads, etc upgrade - that gives pretty good power as well.

Cheers,

David

Thanks for your time
Tim @ www.mindovermotorsports.com has done a couple C2S-TT motors. They have one in the shop now that will an absolute monster (800+bhp) dialed back to 550bhp or so for the street. I've seen the work in progress, very impressive and will be without a doubt scary fast especially 2WD. Buying a TT will be less $$ just not as exclusive....and yes, the considerations above and others add up to more $$. I keep meaning to snap a few photos next time I'm there of that and a couple other interesting toys there (my fav - the Cayman with X51 3.8 PSS9 and the best one off exhaust I've ever heard).

David in LA.

I have been setting aside money for the Protomotive Stage II conversion. What do you mean Todd has moved? The web site is still up. What gives?

There was a posting on another thread that said he moved to Arkansas or some other state...no longer on the west coast.

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....

Sorry, I don't still have the write up on the conversion. But it was Excellence magazine April 2006 - in case you have access to some back issues. Can also be ordered online.

$10k for TT's and 400hp
vs.
$20k for 9M and 325 hp

Someone do the math on dollars per hp.
