kits can range anywhere from 6 - 12 grand.. depending if u can still find a used LMS supercharger kit out there or Tom's Supercharger and wait months for it to arrive.. Then expect to pay additional couple grand to have it installed assuming u find a shop that knows what they are doing. so be ready to spend 8 - 15 grand plus. Then be seriously disappointed with the results that u just spend all that money and u barely get 30 - 50 hp out of it.

There isn't much on the market for superchargers or even turbos at the moment for the IS. LMS came out with a supercharger a few years ago, but it was discontinued. For more clarification, here's a quote from Kurtz who know's his s***.
The LMS kit delivered about 40 rwhp for about $6000.
You can likely cobble your own SC kit together cheaper if you can just get the mounting/fittment stuff someplace (or know someone who can make it cheap) but it's still unlikely to do a whole lot better than $100 per hp. (which again seems kinda insanely high, and makes this option no better than just getting a faster IS for the 350 guys and WAY worse than getting a faster IS for the 250 guys)
The problem is the inability to run more than 5-6 lbs of boost safely on a ~12:1 compression engine.
Even TOMs in Japan, with access to reprogramming the ECU, doesn't exceed 6 lbs of boost (5.8 IIRC versus the 5 lbs of the LMS kit, and TOMs requires 100 octane to manage that and costs $10,000)
You can get a BIT higher if you add some kind of additional injection system (alky/meth/water) but that ups cost and complexity for again, pretty modest added gains.

word...doing it right will cost you around 5k, and i heard you only get around 50 rhp more with a sc setup (without any engine problems in the long run). best bet is to trade it in and get a ISF. to much problems occur with any FI setup cars.
