I purchase some AEM pulley Kit on ebay for my 00 Si , The dude wanted 128.00 buy it now or best offer. My offers was 60.00 bucks and he took the bait.

The total came out to be 73.00 with shipping charges..."brand New"

SO was it worth it or not..I just like how they look on the engine.
What gains can I expect out of it. If i don't gain much it's still cool

 

You should post up some feedback. I've been interested in underdrive pulleys for awhile like unothodox or aem, but I've heard mixed results with them. They claim to give something like 2-3 extra hp to the wheels because of less rotational drag on the belts, resultingin freed up power. I almost got them aswell for $70 off of ebay but decided not to. Did you put them on yourself?

 

Good for bling factor... not so much for performance. Do not go with unorthodox because it includes a crank pulley which is not balanced like the stock one is, which will cause damage to the engine.

 

Will these cause damage to the engine...I just ordered them

 

Not the alternator and a/c pullys, they do not need to be balanced like the crank pulley, it is the crank pulley from unorthodox that is not balanced and will cause engine damage. AEM does not include a crank pulley so you are fine.

 

So where do the AEM pulleys go...I never installed these before and it will be the 1st set im going to do

 

You should really do some research on things before you buy them...

One of them replaces your a/c pully and the other replaces your alternator pully. It will come with instructions so I would check them first but if I recall correctly you are going to need a chain wrench or something else to hold the pully still while you unbolt it. It shouldn't be to hard but read all the way through the instructions before you start. If you get stuck during install then post back and I'm sure someone can help you.

Do the a/c one first so if you get stuck you can still drive your car until it is fixed, if you get stuck half way through your alternator pully then you aren't going to be able to drive your car very far.

 

Cool don't sound to big of a deal to installed...Yeah I heard that thispulleys will pass emission because some place here in Cali are really dick-s. I know I should be fine

 

haha what happens if you dont have a/c cuz i bought them for my 02 dx coupe and it doesnt have a/c...

 

So you installed them and you a/c doesn't work anymore ?
