I've been checking out the AEM pulley kits since I had a 2.2. Are they worth the money? Worth the hassel of installing them? Or worth taking it to a shop and paying to have it done?

Nothing is worth taking it to the shop if you know how to do it yourself. I know of people who have done alit with the 2200 and they can turn out nice, They will give you more of an edge, it just depends on how much you are really looking to get out of the pulleys

Should I notice a difference in speed or anything, also do you know if I could install them without taking the engine out? Because it seems pretty tight to me.

wait your sig say z24 but you said these were on your 2.2?

He said he was considering it when he did have a 2.2 and now that he has a 2.4 he's considering them for it.
