2004 Tacoma Supercharger


Recommended Posts

Hi all,

I just bought a 2004 Tacoma w/ the V6 and am considering adding a TRD supercharger and 7 injector kit, but have a few questions...

1) I don't see a supercharger kit listed for the '04. Even on the Toyota TRD websight, it seems to stop at '03. Will the '03 kit work? Same thing for the 7th injector - will the '03 kit work on an '04 tacoma?

2) Anybody with a recent model Tacoma know how badly the kit affect highway milage? Its already only 19 mpg, if it drops below 14, I might decide the cost isn't worth it.

3) Anybody know how many hours the dealer will charge for the supercharger and 7th injector kit install?

4) How does this affect reliability (assuming no abuse by myself)? Should I spring the $1000 for the extended warrenty?

5) I have also noticed that the horsepower boost claims in increased horsepower are lower than the claims in increased peak horsepower, therefor I assume the biggest horsepower gains are at the non-peak region of the HP curve. Anybody have a link to the HP/torque curve for the supercharger with the 7th injector? (I've only been able to find it for the supercharger without the 7th injector)

6) Any other issues this this modification I should be aware of?
