Aluminum/lightweight pulley set wanted

The accessory belt pulleys on my 91 3000GT are going bad and getting pretty noisy. I want to replace all the pulleys and was wondering if anyone knows where I can get a more lightweight or performance set of pulleys to reduce engine drag. Any upgrade from the OEM pulleys would be nice if there is a set!

A friend of mine over here in Sweden, whom is also fairly known overseas on this platform, bought the idler pulleys that Evospec Performance offers. About three years ago and he was very impressed once he received them. Can’t remember he’s mentioned any complaints since he put them on.

I’m tempted buying the same set, but have yet to pull the trigger. I have bought from Evospec though, but that was their diff cover and RWS plug, still uninstalled but I wouldn’t hesitate order from them again.

This is very cool. Thank you for introducing me to this seller!
