TRD makes a supercharger for the 2003, 2004 4runner 4.7L V8, the eaton m90 (TRD), but its gonna cost a pretty penny, around $3,788.00

read this site in reguards to supercharger. it is a detailed site about the do's and don'ts about this subject. many other items need to be tuned and/or upgraded to get full performance. it will end up costing u over 5 figures by the time your done.he does dyno test and everything. he even proves that a K&N filter decreases horsepower.
