I understand that 968's have a VTEC system. How come no one has been able to adapt this to the 928 ? Answer in ENGLISH please!

 

Is this what you mean?

 

Steve,
I am impressed.
What's been the history since the install?
If I start with a stock S4 engine, what modifications are required (strictly for the adaptation/conversion)? What would it cost?

 

There's a reason Sterling G. is the only one to pull this off. Besides the cost of custom cams, engine management and other hardware, it was probably a major PITA with countless hours of trial and error. The results are stunning according to everyone who has ridden in the car. We're all waiting for some dyno numbers once Sterling works out the final tuning. Should be awesome! He updates his website regularly with progress reports, so keep checking back.

 

Any guesses on costs?
I suspect it is way up in five figures...

 

I wonder when sterling will start to build and sell these engines?

 

I am sure he would be thrilled to get money back from his investment of knowledge.... Anyone have checkbook with an extra 100k laying around?

 

I spent much time with Sterling at Wichita, it's easy .. he's a very nice guy. And his car is exactly like the Factory would have done it. From what I can glean from Sterling, I predict he will offer a solution in future AS HE SHOULD.

 

I really doubt that Sterling will try to start a business based on building and selling a very expensive engine "upgrade" for the Porsche 928 others have tried that approach only to find that there are a very , very small number of people willing to spend that much money . It is not a very successful business plan . There are a lot more people (but still very few) willing to spend $6 - 8,000 than say $20,000 or $30,000 for increased performance which they only use a small part of the time . Sterling's exercise is a labor of love .

 

Like I said labor of love !! interspersed with periods of hate , loathing, and utter disgust .........

 

Sterling ... Brother .. you don't know it yet, but you willbe building another one I guarantee you I know, because you have done the impossible ... you will do it again.
