Hi, I was wondering if you have an idea of how difficult it is to change the supercharger in the Previa. The deal thinks ours might be in its way out and we really don't want to hand over the money to them, if we can help it.I have a Toyota super charger in my attic I mistakenly bought it for my 94 Previa a few months back. I got a wrong diagnosis from my Toyota dealer. Turns out the idler arm pully was the problem. I got it from a company who imports them from Japan. I never opened it. Is is removed form a car with 60K miles. They guaranteed it for me but I never installed it. Let me know if you know anybody who wants it for $100 plus shipping from Houston, TX.
