Thread: SR20 lightweight 4-pulley set?

Although i know miroslav jagos made a custom 4 piece or 3 piece from outside the US , i really wish the Gspec wp pulley had bunch of holes to reduce most of the weight to make it a genuine super light pulley with cut a lot of holes in it tho

What header is that? Looks nice. More pics... Also, is your engine mount cracked?

No, just needed the Alt pulley. I am currently running the GSpec WP pulley and an ATI crank, the Alt is rear mounted with the OBX Alt pulley. I have voltage issues at idle if I have my lights on at night. With the fogs on I drop to around 12.5v at idle, once I start moving it goes back up to 14v.

Storm, I know I asked Greg at GSpec awhile ago and he said he could make any custom pulley for around $100-120. Not sure if that price still stands but you could ask to see if he still will. I am still thinking of having a custom Alt pulley made to reduce the under drive for the issue I am having.

Has anyone actually weighed one of these lightweight pullies to see how much lighter they actually are compared to stock?

Header is a custom header made by armonic performance , yes my mount is broken not worry since im just mocking stages of my build but really tempted to get the bigger mount pins that charlie salazar offers later down the road while im at it

I have noticed some idle volt drops on my cars too with fogs on radio on and pretty much most of the things on , what i did to fix it was to have my idle raised just around .980-1rpm anything below puts low voltage anything higher full 14v hope you can dail in yours

I have a similar setup in my Nismotronic ECU. If voltage drops too low, i think around 12v, the RPM raises to 1-1.2K RPM. I do not like have such a low voltage at idle, I would like to get it a bit more stable with just the headlights on.
