Turbo S2000 for next race season
I tried the built motor route. Spent well over $15k to try to get max NA power. I was told to expect something around 285 RWHP, which is probably achievable with the right builder. Mine was definitely not the right one ... I only saw a net of under 20 RWP ... but that is another story.
I ended up going with a Comptech supercharger with aftercooler set up on a new F22c. Required an oil cooler to keep on track temps reasonable; though it prooved to be a reliable track setup.
Last year I started W2W racing with in the local MPRA series, some local SCCA and NASA. The super charger hits me as hard for classing as a turbo, but it doesn't deliver the same low and mid range power.
After about 6 months of weighting options I've decided to switch my dedicated track car to turbo for next season.
Super charger is out of the car:
And soon to be replaced by what's in the box!

I looked at a lot of different options for the turbo. Heat management and reliability were two significant considerations together with a focus on going with a well proven system. I've done enough $$$ experimentation and did not want to go that route again.
I couldn't find anyone competiting in W2W with turbo S2000 or even anyone competiting in time trials or regular HPDEs with one, so I ended up going with what by most all accounts has proven to be a reliable street and drag racing setup -- yeah, drag racing an S2000 makes NO sense to me either ... what a waste of a perfectly good track car! The InlinePro kit had good positive reviews and after some research and discussion I came to the conclusion that the cast iron manifold was actually a good option to help with the heat and reliability of the turbo on a track car.
I'm sure other custom setups could be built up, but that would too likely lead me down the $$$ experimentation path.
I'll update this thread with more details and my impressions once the turbo is in and I get it out on track next year.

cbender tracked his Speedcraft car pretty regularly, albeit at a low boost setting. (around 300whp) I've worked on another Speedcraft car that saw plenty of open track days, but on 17psi+.
I'd recommend a liquid cooled BB turbo, and keeping your oil cooler. I'd also insulate everything around the turbo from the heat.

I appreciate the tips.
I did go with a liquid cooled bb turbo. What is material do you recommend for insulation?
As far as power, I'm only looking to make 300 to 350 RWHP.

How reliable is a 17+ psi track car? How is drivability? I'm guessing that he had a good 450hp+. Was he able to put down that kind of power on the track?
We used foil backed fiberglass as well as Aeroquip firesleeve on the hoses.
