I'm surprised this is the first you're hearing of this kit. It has been around for a long time. The only problem is, I've yet to see a car run this kit without going up in smoke some time soon after. Chris from HondaPrelude.com had the most success, making 206WHP for at least a year before he had some kind of engine fire.

I would personally go with an H22 swap instead of the turbo B20. If you have the time and the knowledge to tune it perfectly, a turbo B20 can work. The problem is most people end up running lean and getting detonation, which will destroy the engine. With the H22, you wouldn't be sacrificing reliability in order to get a ton of power.
