    DC5 Auto tensioner pulley diameter

    Hey guys, was wondering if someone could clear this up for me or maybe help me measure it on your cars. I'm after the diameter for the belt auto-tensioner pulley, I can't seem to confirm if it's either 2.5" or 3".

    Just need to know since i'm halfway to installing a JRSC race kit with a 4" pulley and a modified OEM auto tensioner that has a 3" pulley (measured with a vernier caliper) and it seems to be abit close to the blower pulley... hoping i could swap it out for a 2.5" tensioner pulley.

    Not sure if you found your answer, but I bought a replacement pulley that is 76.5mm. I used theGates 38278 Belt Tensioner from Amazon and its prefect on a k20a2 or k24 with all the k20 accessories and crank pulley. Hope this helps.
