whats up guys glad the site is finally somewhat operational again. so hears the deal i have a jrsc-r with the 4.0 pulley and i want to run the 3.8 and squeeze out a little more power. Now is it the 2.5 tensioner from the rsx kit i need #772-120 and then just get the smalley pulley?

On a side note any predictions on what my whp might be? my setup is
Skunk2 S1 cams
Injen CAI
HKS exhaust obx loop muffler
currently 225/165

Yep, checked my old invoice when I ordered the 2.5 idler - that's the right part number.
