My name is Chris and I recently bought a '06 2.5T AWD s60. I'm looking to up the front HP a little without going to the extremes of adding a turbo or the like. Any suggestions?

 

I just got my 06 s60 also (last week). From what I have seen, modding these cars is fairly similar to modding any other car. Start out with some bolt-ons if thats what tickles your fancy. Let it breathe better, grab an intake. Then you will want it to flow better, so you can upgrade the exhaust. An aftermarket ECU (ipd, est, etc.) also looks like it will improve your numbers quite a bit.
Check out the resources sticky. Its been a big help for me as I'm going through the same thing that you are!

 

Absolutely - pretty easy - just need to know your budget!

 

I think it already has a turbo...
