Another Efan Question

I know most of you reccommend the Taurus efan, but I can get a new Zircon S-Type 16" efan for 40 bucks. On thing I was wondering was, I have an 85 amp alternator (Kragen recomended) but I kinda think I should have got the 100-amp even though they said it was for 'Baja". My question is, should I get that one anyway or will the 85 handle it? Do I have to change any wiring?
