I don't know about turbo's but I really wouldn't bother with an induction kit. Manufacturers don't spend many man hours designing air boxes that choke the engine. My experience of using induction kits has never brought up any worthy results. In fact you will probably rob the engine of BHP as it will be breathing hot air, which is less dense from the engine bay. The only thing they do is make the car sound louder. If you really want one you can get many universal ones on auction sites.
If you are looking at a turbo then a standard fit induction kit will be practically useless anyway as you will have to re-design the induction system.
I suppose a smallish turbo would be best unless you are planning on lowering the compression ratio. If you intend to leave the engine standard and just add a turbo then your best bet is probably the one that Saab use in their 9-5. There are two variants, the 2.0T is high pressure however they also do a 2.0t which is a low pressure turbo designed to increase MPG and mid range torque.
Use the low pressure one and you are less likely to get detonation and will be able to run the turbo at higher speeds.
Best of luck if you do attempt it.
