Dual Pulley Install

something like that, the bracket should be easy to make, you just have to make the bracket adjustable so the belt tension is adjustable with the V belt setup, will probably need a shorter belt too. I plan to do this on my car. Cleans up the top of the engine some more also, I really like this modification.

well duh, but it probably costs more time and money to make a NA rx-7 go fast than it does a t2....
it was just a suggestion, I like the idea, lowers CG, reduces rotating mass (single belt pulleys and single belt), puts weight back on the drivers side of the motor where it's been removed if you
ditched the AC/PS hopefully getting back some balance previously had.... and probably keeps the alternator cooler since the heat won't be coming up off the motor soaking the alternator.
sounds good ot me.

Ok, I took the alt and pulley to pep boys. They took the stock off, and on of the guys thought it broke in half. That's when I started questioning their intelligence. So they put the new one on. It spins fine about 180 degrees, but the other half of the revolution is stiff. One guy says I need a spacer a hair longer (the one behind the pulley). He says he doesn't have one. So, being the paranoid-of-people-behind-counters guy that I am, I then took it to Advance Discount Auto Parts. The same thing happened, spins halfway, then stiff the other half. It looks like the pulley is rubbing ever-so-slightly against the alt housing. This guy tells me I'd need a longer shaft, because if I put a bigger spacer on, the nut wouldn't have enough space on the shaft (with stock, the nut is pretty much flush at the shaft).
What's the deal? Is the pulley a little off, or is my alt housing a little off? Or, considering they used an impact gun, should I just tighten it down by hand?

Sounds like you may have a reman Alt. that is slightly "off". put some prussian blue on the back side of the pulley to see where it is rubbing. You can also use "shim stock" to move it out ever so slightly.
