So performance wise, the UR pulley is better than the KJR?

How much should I be looking at to have a UR crank pulley installed?
Are we talking big money?

1.5 hours X $80 = $120

This is for the single crank pulley...

the other 2 pulley's are for looks...

Our service department (we do not make pricing) charge an additinal 2 hours = $160

I may have been just talked out of it by a guy at Jotech Motorsports. He advised me that if I was going to do the pulleys, to only to the accessories and NOT the crank.....citing issues with the balance (yes, I know this has been the source of debate for a long time). However, the reak gains are made from doing it to the crank pulley. No point in just doing the other pulleys if you aren't doing the crank.

Crap, I really wanted to do it.

Can someone convince me to go ahead with it?

thats fine...

68000 miles... no problem...

stock crank pulley does not have a harmonic damper...

stock crank pulley is cast iron... most likely more unballanced then a CNC'ed Billet Aluminum pulley...

FYI, you can buy them directly from KJR for $170 shipped in either silver or anodized black. http://www.kjrperformance.com/shop/

Ok, of all people....Doug at Crawford told me that the crank pulley will most likely not hurt my car. He said that he's only seen one car with issues after installing a underdrive pulley, but that car had also had it's redline raised (I'm not sure the significance to that). He said if I haven't had a re-flash done to my car that raised the redline, everything should be good to do.

He also assured me the the water pump isn't run off the crank, so there shouldn't be a cooling issue either (I worry about this, since I live in extremely hot Texas). The only read thing I should notice is it underdriving the AC and maybe the power steering.

With that said, I feel pretty confident between what Jason at Performance Nissan and Doug at Crawford have said.

I had the UR crank pulley installed yesterday, by the way I love it Revs faster and a tad to the butt dyno wheels spin with ease in first just mashing the gas(used to have the pop clutch) . My next mod was ECU flash and Doug said not to do that. I am confused why would raising redline effect the crank? Not to steal the thread sorry

Not sure, but I'm not going to question him. He knows much more than I do.
He just said "Raising redline + UD Pulley= Potential Bad News".
