how would one set up an anti-lag setup on the S2K?

 

There is always an answer to "how" but there is rarely a good answer to "why".

I believe most modern stand-alone ECUs can simulate this by injecting fuel in lift throttle situations and retarding spark so that ignition occurs primarily on the way out of the engine in the manifold. Correct me if I'm wrong.

It's a good way to burn up your turbocharger. WRC teams have big $$ and sponsorship...they can afford to outfit their cars with new components at will.

 

Maybe on peak HP(nice for dyno days, but does not nessesarily mean you have a fast car) and top speed.
Current WRC cars produce about 340hp(with restrictor), en have 300+hp at 3000rpm, and will blow any FI s2000 away.
Without restrictor it will produce more.
Another advantage is that its specifically made for a ~2.0l engine.
Maybe it's not the best combination with a 2WD car, but we'll see.

 

Gotta love Wikipedia...

Sure the WRC would anihilate an FI S2000. But this turbo on an S2000 would not be a good choice for a few reasons. First off, the F20 motor is too efficient for something this small without a restrictor. One can get away with using a much larger turbo without many of the downsides of upsizing. Secondly, what pressure ratio must be sustained to provide enough air flow for 300 HP @ 3,000 RPM. We'd be in the 25-30+ psi range and no one on pump gas would dream of using that daily.

When it all boils down to it, look at the sizing of this turbo. It's nice for sure, but designed for a very specific purpose: high pressure ratio, restricted flow, and ALS. Size wise...it's a disco potato.
