350z unorthodox racing underdrive crank pulley
35th Anniversary Grey 350z - Motordyne TDX2 Shockwave exhaust , JWT popcharger, MREV2 plenum , 5/16 plenum spacer , MD ART pipes, UR Crank pulley, CE28 volk racing wheels
If its branded unorthodox racing (UR) as your mod list suggests then yes by all means they are reputable, and a worthwhile mod.
I have personally installed and clocked up ks with the FULL UR set on all my Zs (300zx NA, 300zx TT, and 350Z) with no problems.
Many other Z owners have used UR long term too.
But whilst un-dampened/lightened crank pulleys have received some negative reports its usually due to the inline 6 configurations from the likes of skyline and supra owners. The shorter crank/V6 configuration in Zs I guess make them less susceptible to such harmonic issues.
