I also have been doing my research and reasoning with myself which route I would like to take if any. I have considered the STS TT kit and the ECS S/C or A&A S/C and just the good old fashioned all motor. I don't know which way I would like to go either. The S/C seems to be the cheapest route to 500 rwhp. I have always been a turbo fan and would go that route but its another $2000 or so for the same hp. Then all motor is expensive but generally is also a favorite for various reasons (sound probably the biggest reason).
***do not quote me on prices or hp becuase I am sure there are ways to do any of them for a "reasonable" amount of money.
If I did not have to worry about smog I would love to go all motor, but I live in Ca so smog is an issue. For me if I am serious and feel like paying to play I will obviously go with some sort of FI. The S/C seems like a very good candidate. Good luck I am sure you will never have enough HP though
