Ok so for all of those i4 lovers out ther i'd say the underdrive pulley and FSZE cam are a definate good idea, coupled together i felt a very noticable difference in power. The cam freed up between 10-15hp and the pulley between 8-10, i haven't romped on her yet as i just installed the stuff but i could allready feel a little extra power specially as you reach around the 3000+ rpm range.
Also now that i have one i want another... wherethe hell do i find the exhaust cam upgrade? and the rest of the pulleys, c'mon unorthadox you make us one pulley and leave us hangin? Adjustable cam gears would be sweet to. Anyway i have a 194 2.0 and id like the exhaust cam and lightened pulleys (the rest of them) and some adjustable cam gears, ive searched out on them and not found a thing.

Congrats on your mods. I wish my 2.0 had more balls. The jspec exhuast cam is the same as the aspec. From what I've read anyway.

ya that the whole reason for the lifters making noise (i think). So are the jpec cams the same as the aspec?

The jspec exhaust cam was the same as the aspec. But there was a Mazdaspeed exhaust cam, but it didn't have a gear to turn the distributor.

One of the most mis-interpreted things about the ZE exhuast cam is that its the same as the A-Spec. This is actually not true. People assumed this cuase people werent using the ZE exhuast cam, but its really becuase of the disty gear like the mazdaspeed one. The one way to get some things smoothed out is to get the grind from the ZE's exhuast cam and and have it reground onto your a-spec exhuast cam. Soon I actually plan to go beyond both cams...gonna make a aggressive intake and exhuast cam grind. Go beyond the 6 more degrees of duration that the ZE intake cam has.
