Will the pulley system fit

[goatnipples2002]

I wanted to buy an AEM underdrive pulley system for my D15B7, but they don't make it for that engine. Is there a system for another engine that would be interchangable with my engine? If not is there away to make it fit? Does this system really make a big difference in torque/hp?

i would think they would be interchangeable, but i'm not sure. your best bet would be to call AEM and ask them.

as to whether or not its a difference, some say yes, and some say theyre a waste. So, I'd say the increase isnt much or there would be alot more talk about them.

What do they say it is intended to do?

the most noticeable thing from them is the eye candy :yes:

So I shouldn't waste the money? Do the AEM cam gears do anything? On this forum or another somebody told me an adjustable cam gear will give you 20 horses if it's tuned right. Is this true?

You should do upgraded cams with adjustable cam gears to get the full benefit

you will not really get a gain with the cam gear. what you can do with it is mess around with the power band a little, so you can gain some low end at the expense of top end and visa versa. If you upgrade the cam at the same time, even better, you'll gain power across the board and then you can play with the power band again and put the power where you want it.

BTW you only have one cam so you'll only need one cam gear and one upgraded cam.
