Underdrive means it slows them down.

 

only problem I had with my 3pc pulley kit was that as soon as I put it on the car ran like crap. Once I unplugged the battery for a bit and let the car warm up it seems to be fine. Just so you know the underdrive pulley (UR) does not fit perfectly with the crank bolt, some washers may be needed.

 

Mine fit just fine without washers, but I didn't buy the 3 piece set.

 

There are to many mixed feeling on this. I'm gonna do my suspension instead, Just ordered sway bars front and back, Ground control coilovers, What's a good shock for the civic?

 

I've seen the negative effects of a crank pully on a motor. The oil pump failed due to the design of the lightweight pulleys. Compare one to the OEM pully...

I absolutely do not recommend any change in pulleys, especially on a stock motor. I removed mine as soon as I saw what it can do to a motor. The potential damage is not worth the minimal gain.

Additionally, the turbo/super argument in this instance is compeltely and utterly moot. It does not have anything to do with OEM/replacement pulleys.

 

Many people like Koni Yellows.

 

yep, or the Sp3 Yellows...

Ive been fond of AGXs in the past too

 

i have ground controls and koni yellow

only problem i have is that the rear cround controls adjustment bolt is stuck and i cant adjust my rear height

 

Already decieded against it but I thought the oil pump had nothing to the crank, buddy said thats run of the cam?

 

:lmao:

Your buddy's a moron. The oil pump is just behind the crank pulley.
