Hi, I was wondering if there was a difference between the 03 and 04 turbo, and if so what is the difference?

Thanks!

I believe the only difference is in the number of vanes in the turbo. The 03 has 10 and the 04 has 13 I think. Someone correct me if I am wrong on those numbers.

I don't think it caused any changes in power since both years were rated for the same hp and tq. It was meant to change the sound of the turbo. Hence the 03 turbo having the desirable whistle.

I pulled this info from a Ford book I have saved on my computer that lists all the changes to the 04 model year:

Turbocharger Exhaust Turbine Wheel
• Three fins have been added to the turbine
wheel of the turbocharger.
• These additional fins were added to the
turbine wheel in order to improve the
turbocharger’s sound characteristics
