well i have done some slight research for my s 40 as for boost...no one seems to make jack for it... any one know????

 

1. What year s40?

2. What model s40?

3. Are you trying to convert a N/A s40 into a turbo model? If this is your answer don't waste your time and money. It would be cheaper to sell your N/A and buy an already turbocharged model.

Ok after reading a previous post you posted I found that you have a 2005 Volvo s40 T5 model FWD. With that said where have you been looking? Because I have created a big database of links and other helpful information in the General Volvo section of this forum in the Pinned thread titled Volvo Forum Resources Thread, it is linked below for you.

I don't know but I believe there is some good parts available to you and ECU upgrades to raise your boost levels. If your looking for a cheap fix it isn't going to happen.

 

what do you want as far as boost? You want a boost controller? Be more specific...

 

There's a bunch of things you could do with an '05. You just have to be more specific...

BTW, love your sig!!!
