Engine pulleys upgrade

Haven't done this on a G, but the technology is sound, and it will free up horsepower (it doesn't actually make any horsepower). Keep in mind though - any ancilliary system you modify with a different size pulley will spin slower, thus affecting it's performance. Your A/C may not be as efficient and your alternator may not be able to keep your battery charged. So just keep this and your driving style in mind when you determine your pulley sizes.

There's another consideration, and that's engine harmonics, which you could be impacting by putting a LW set of pulleys on the front. IDK whether or not the crank pulley in our cars is also a harmonic damper... that's pretty deep into the tech weeds for me. And I believe that's a more relevant consideration when you convert your NA engine to a forced induction setup with a higher redline than stock, or if you use a lightweight flywheel in your manual transmission. Understand, I'm no mechanical engineer, and these are mostly hearsay opinions based on forum research over the years.
Full disclosure, I bought a lightweight crank pulley from Unorthodox Racing for my old Maxima, but the only perceived effect was that it revved quicker while in neutral. While engaged in gear... meh. No real return on investment, except bragging rights.
And in that context, never underestimate the value of bragging rights.

Pulleys are a waste of money and not worth the install headaches and risks IMO.
