If it's a TD06 16G then its a popular turbo for Mitsubishi VR4's. Cordia.power.com will have some info on hp flow rates etc. Also check the yank Diamond Star Motors forums. If you type these into google you will find some info. I was unaware it was a Greddy item and thought it was just a mitsi JDM unit. They are great turbo's that's for sure!
