EDIT: Oh, and in these days of modern time (let's see who get THAT one) 109K is NOT high mileage. The only vehicle I have with less that that is Vanna the Van who came w/low mileage.

There is nothing like striking while the iron is hot, but it might be worth talking to someone who know which type blower would be better for a track car centrifugal or postive displacement.

I am with Dan turbos are better and they don't put as much stress on the crank.

Russell makes a good point. Turbos, while excellent, DO have a certain amount of "spool-up" time whereas positive displacement blowers are instant which might be better for coming out of a corner, and more predictable. Research.......

I've always been under the impression that a simple MAP sensor change is all modern computer controled engines need to function correctly with boost ranges in the 1-3 atmospheres range.
Higher boost ranges need custom programming for certain, but the factory computers seem to be able to adjust fuel with the range of a 3-bar map sensor.
Most N/A factory sensors are a 1-bar, but 3-bar ones seem to be readily available.
Of all the paths you take in life - make sure a few of them are dirt.

Turbos.... they so depend on the motor. Worst part is the kits, there are some that are excellent and bolt right in place. There are others that make you wonder what they were thinking. That's not so true with superchargers (blower goes on top, supercharger goes on the side - both are belt driven) - the ones I've seen truly are a bolt-on affair.
Specifically the Mustang.... excellent revs, not so excellent torque - which makes the blower the better of the ideas because it starts developing boost at just-off idle thus giving you better torque and making you faster everywhere.
But, it's interesting you bring this up... Mighty Car Mods is going to test a blown Miata vs. a turbo'd Miata - all they say directly applies to your decision (which, I might add, is awesome)
Part 1 is here
follow up with part 2 and wait impatiently for part 3 (the test) like I am.

Sue's rationed that we should just rent a car trailer from U-Haul, no more often that we'll use it, two or three times per year and no telling how long we'll stay into doing it. When I retire (1 year 11 months, 13 days) we may just do the track thing once per year. And the hell with the fence gate if we rent a trailer. It makes sense.
And blower vs. turbo - with the boost on the turbo being linear, Red will still be into the high RPM's to make some time between curves. That's what ran Red hot at AMP last time out, I was all over the redline in 3rd gear to get some pull before the braking zone, all day. I'm thinking (and please correct me) with a blower I may be able to put the car in 4th gear at times and still get good pull and keep the R's down and keep it running cooler and still turn some decent lap times.
And I'm liking this one so far. When I was fantasizing a few years ago, Rousch (sp?) had a Mustang blower for over $10,000. They're coming down in price across the market as the technology improves I suppose, like everything else does.

U-haul.. Tend to be 50/50 (tires on trailer right in the middle.
Ideally the rear tire needs to be on the cross brace right behind the rear tire of the trailer.
The U-haul does not have length to scoot up.. Maybe for a mustang..
I always load the rear tire of the car being hauled close to the rear tire of the trailer.
My trailer is 60/40. Look around at what private trailers are like.. Pretty much none are 50/50
