thanks man...

 

Nissan makes the best crank pulleys from what i've seen...

 

Like you've seen anything.....

 

i like the definitive motorsports one just b/c its the lightest but i need to get on this weekend....any opinions?

 

I have an unorthodox unit and it has given me zero problems. It's been on the car almost 4 years now.
I like it.

 

I have the DMS. Had it for about 3 years, no problems or oil leaks.

 

motostorm was fine on my car...i believe to have seen many claim them to be the lightest

 

it doesn't matter they all give the same hp basically. only difference would be quality and craftsmanship

 

I have a Motostorm... no problems with it

 

This would be true assuming they gave any HP to begin with.

 

I bought a OBX UDP just make sure you lockthight the ckps ring bolts so they dont back off and chew on your timing chain cover.I had to measure between the pulleys 4 the right size belts through napa they are
PN#25-060410 (a/c)$22
PN#25-040310 (pwstr)$12
As far as performance my butt dyno feels the hp & the other 4th gens i pass can see the difference.lol
4 my next swap i ll be using a stock pulley first dyno then obx 2nd to see exact hp gain. but http://www.motorvate.ca/mvp.php/521 Should help

 

Butt dyno's can be VERY inaccurate. Still not convinced they do anything.
