 If you Need at turbo - like somebody in a Mountain region might to get up over ridge lines etc, or for some other reason then I would say stick with it.  If the tubo is just a "nice to have" then you might want to reconsider. 
 
 Hi Ed,
 
It wasn't John that couldn't decide which way to go, it was me, which shouldn't be a big surprise :-)  
 
I realized a couple things today:
 
1-  I don't need a turbo to fly an RV-3 the way Van intended it to be flown.
2-  I do need a turbo to fly it the way I want it to fly.
 
I keep coming back to the reality that this is a toy, and serves no practical purpose.  Ultimately, I'd like this plane to make a performance statement.  That has been my goal all along, so there's no reason to quit now.  If I wanted a normal RV-3, I'd have an O-320. 
 
OK, that sounded good right?  Well, here's the real story.  I kept babbling to my wife about the pros and cons of turbo vs non-turbo, and she basically told me to shut up, and get the damn turbo, since it's what I really want.  She knows that I would eventually decided to do that anyway, so she saved me some time, or she's after the life insurance money...  Either way- smart woman :-)
 
In other news- I got that ultra-mini alternator today, and man is that thing small.  It looks about a quarter of the size of the stock Mazda unit. 
 
Also, while at the airport today, I set my relieve valve to limit the boost to 5 psi.  At least now I can make less exciting takeoffs.  Usually, I spend the first hundred or so feet chasing the throttle around to get the boost right.  This isn't an ideal solution, but it should be interesting to see if I get better climb performance at full throttle, and 5psi, vs when I was at about half throttle, and 5psi.  Yep, just call me Mr. experimental. 
 
Cheers,
Rusty (Hello Turbonetics, goodbye money)
