This is some thing else i have my eye on for my New 03 LX 470. I have found out that this kit wll fit the 4.7 lt in the Lexus. The only this is that the engine cover would need to be removed or modified to fit after install. Chaeck out this link. Also here is a picture of the 4.7 with the kit.

Stelios,

Hey, can you input some of your observations? Any pics? If my supercharger kit falls through for the SC4 then I will put one of these on the LX for sure.
