Just do the damn ATI damper pulley while you have the engine out. That way you can use an impact gun on the damn pulley nut, and not have to drop your sway bar, etc.

LEARN FROM MY MISTAKES!!

Yeah when we did my timing belt we used a chain wrench on the crank pulley. It made life a lot easier to say the least.

I just used 2 pry bars to get the stock pulley off.

BY THE WAY- make sure you put the lower timing belt cover on before sucking the damn pulley onto the crank all the way.

Normally you can put the timing belt sprocket on and do the timing belt, then the cover, then the crank pulley/harmonic balancer... its all 1 piece with the new ATI unit, so you need to make sure you combine those steps. I had to cut the s*** out of my cover to get it fit with the pulley on there (so I could use my timing marks). You really don't want to have to pull the pulley off after putting it on.

Also, the ATI harmonic damper/pulley has a larger OD pulley for the power steering section (so it will overdrive your power steering and AC compressor). I read Flyin miata's website, and they say that their belts still fit, but mine did not.

I went with a belt roughly 10mm longer from Advance Auto parts, Drive Rite part number 378K4.
