Guys I came across this turbo kit for the e53... Not much info on it...
See link:
E53 X5 Turbo Kit 98-06 : Bimmer Parts Wheels | Headlights For BMW | Tail Lights Accessories
What you guys think of this?? did you ever see one installed on a 4.8is?? The engine space is tight I am trying to figure out where I would even mount the extra Intercooler & all.. Any opinions on this system would be appreciated .. Also if you guys know of any good *REAL/TRUE* Trubo kits for the 4.8is let me know..
