Do they help? Are they worth it at all?

 

cam gears for tunning , getting every juice out of the motor
pullies different opinions , IMO not worth it !

 

I wouldn't bother with the pullies. You should get cam gears later on when your modding.

Actually I have always used an underdrive crank pulley. Shed's rotational weight off the crank, makes 4-6 whp and no tuning involved. Plus not too expensive. No downside to going with them unless you subscrive to the paranoia about harmonic dampeners.

 

i felt i nice difference after instaling my pullies at around 4000 rpm
i would say defenetly worth it car feels smother too!

 

which pulley's? AEM set or Unorthodox Crank?

 

Do AEM, I heard the unorthodox fawks up your main bearings... course i've just heard this and never seen it personaly.

 

83,000 miles with the full Unorthodox pulley set. No problems & runs smooth now as when I bought her in '99. Ask anyone who's ridden with me - I DO test the higher 1/2 of the rpm range every damn time I get in the car.

Pullies rock. Except when the bolt holding the AC tensioner pulley snaps off & lodges against the aluminum crank pulley Can you say "aluminum lathe"

 

hmmm........is that "minor" bolt snapping common?

I have found 1 other person who has had it happen. The odd thing is that the bolt that snapped doesn't have that much pressure on it, nor did the threads stretch {like they would if you torqued a bolt too tight - don't ask how I know}. It appears to just have been a "bad" bolt that snapped dropping the tensior pulley for the AC down onto the crank pulley & also of course releasing the belt & knocking off the ps belt. FORTUNATELY I was only going ~5mph coming to a stop sign when all hell broke loose under my hood

Needless to say, I used a different bolt I had in my garage from an old Civic exhaust setup that should be stronger (at least I know it held up before )
