Heres some pics of my homemade budget boost project on my Honda, yea i know its not a bimmer, but it gave me something to practice on before i go make a kit for the m3 next winter (I promise it won't be as ghetto:D ) Plan to boost 10-11psi, should be 280-300 @ the wheels in a 2200lb car...Total cost was ~$1500 including fully tuneable engine managment system, injectors and all guages:D

And to keep this BMW oriented...This is next (much nicer setup though, should still be well under $5k)

Vroom Vroom :)

Damn, $1500 for 300 WHP or so?!?! That is awesome man.

So you're planning on turboing the M3 in the winter?? If so, give step-by-step procedures for people like me who don't want to spend so much on a turbo :D

What kind of wrapping is that?
