How much do you want to spend?

Im willing to spend/save whats necessary for what I need. If changing the engine to a M42 or M44, would that cost me the same amount as upgrading the M43 meaning it'll be better ?

Not really worth it... Not because of the engine size, but because of the engine design. You can turbo it but it doesn't respond particularly well to that.
The M43 is a solid, reliable, economical and simple engine but doesn't really tune in the same way the M42 or even M40 (for example) does.

Crunchy knocked up a M42 turbo which was a success by most accounts - more power, and more economy. Have a look here.

 

Oh yup I see. I saw his post it looks really good even for a workshop hack haha What about other mods such as largers cams for example & ITB's? I saw a few modified M43's with street stage cams & ITB's which looks like it could give it a bit more. I'm just looking for something to make my car go a bit harder than what it is now

I have a E46 318CI (M43B19) engine & I was wondering if anyone has done any Forced Induction modifications to this engine? Turbo or Supercharger? I found a youtube vid that shows that someone has done it but it wasn't infortmative it was just for show.

I know some people are probably going to say its not worth it due to being a small engine but the car has sentimental value to me so I am willing to try do it despite power limitations. It won't be the fastest E46 but I want a bit more out of it.

Any other modifications other than Forced Induction will be helpful too.
