Found this on the good ole web and was wondering if anyone has looked into this??
I know it is a yank site but could be good huh

looks like a good kit for the 2nd gens?

Not sure as it does have the Diamante listed near bottom of page.......

"Mitsubishi
6G72
SOHC & DOHC
12V V6"

Even though the DOHC is a 24v, it'll be a kit for 2nd gen V6's
