To any that can offer an opinion, help or advice,

I currently have a normally aspirated 850 sedan. I have been searching around the web to find possible solutions to increase power, more importantly, low end tourque. I am looking to modify the engine so I can increase the tourque, as well as the horsepower at the same time, if that's possible. I found a website called Eastern Aeropsace (www.easternaerospace.com). It offers all sorts of solutions for increasing power. One of them is adding a bolt on turbo to the car, but that would cost over $3,000 and a lot of time. Another one of their solutions involves changing the ECU, has anyone done this? The also offer magnacor wires, is there a real difference when these are installed? Moreover, they offer a large bore on the throttle body, would this have any noticable difference? Fianlly, the sell a larger diameter exhaust, would this result in more power, or just more noise? So my real question is has anyone purchased anything from eastern aerospace, and has it worked out? As well, are there other solutions to increase power in the normally apsirated engine?

One other side question;

A friend of mine owns a 1998 S70 with an alarm system installed. I noticed his lights flash when the doors lock. I imagine that the lights are triggered by a momentary contact connected to the door locks, probably not the alarm. Is it safe to assume that the S70 wiring diagram would shed some light on this change? Can it truly be done?

Thank you to all!
