But if you're wondering why your turbo sale is not going so well you only have yourself to blame.

I know you'll see the irony here, but hey, let's keep this civil. 
The whole SC vs. Turbo thing should be a comparison of merits not a slanging match.
Originally the biggest merit of the Comptech and Vortech kits were exactly that. They are kits. A garage monkey like me can install them in their spare time. This advantage came with a cost too. The kits, whilst adding heaps of top end, do bugger all down low.
Any custom set up is going to be a lot more work as you are charting unknown territory. As there are a lot more turbo options out there a custom FI system is usually turbo rather than SC based, so there is the appearance that turbos are more trouble and harder to install.
But with the advent of the UR kit you finally have a bolt on solution that as fperra can testify is easy to install. And rather than having a tame bottom end it comes with a configured E-manage (if I remember correctly) to tune the mid range too. So you get the ease of a kit with the benefit of better midrange.
The reason I went SC was that at the time the turbo kits weren't particularly well established and I'd have to make a custom manifold anyway as my RHD S has a steering shaft right where most kits mount a turbo. I expect I will upgrade to a turbo at some time in the future.

in term of maintenance both turbo and sc have their own issues
(disregarding turbine wears, oil change etc etc)
SC needs belt replacement and tension check
TC need to replace manifold when this crack
Let attack this topic from another point of view, driveability.
How does the SC feel on track/streets/twisty road compare to TC?
Does the TC power comes on too sudden or does this depend on tuning/turbo selection?
BTW I selected the SC route because of convenience and less stress on the drivetrain/clutch compare to TC. Once my engine is rebuilt and the drivetrain is strengthen....I will be kicking my self for not going the TC route. I love to be able to adjust boost and power by adjusting an electronic boost controller rather than spending a couple of hours changing a SC pulley.

One of the downsides of the SC is the belt tensioners. Neither are auto tensioning.
Do well made manifolds really crack? Is this more a problem with custom SS manifolds or cast ones?
From the POV of drivability the SC kits as standard are pretty linear (as you know) it's just that the power ramp is much steeper.
With a turbo it really is dependant on the set up and turbo choice as to how the power kicks in. I'd personally want to minimise lag rather than just have a ballistic top end. Can anyone comment on how the UR kit is with regards to lag?

Some of my past cars included a custom turbo second gen rx7 and a stock 924 Turbo. In comparison, the UR S2000 has minimal lag. Power comes on much quicked than vtec kick in on stock. I would say that turbo lag is non existant. Of course, I opted for a dual ball bearing turbo.
