thanks guys, glad you liked the post.

One thing that is VERY important on EVERY turbo (bb, non bb, watercooled or not) is to NOT do hot shutdowns. Always let your car idle for a minimum of 30-45 seconds after boosting hard.

shutting the engine off allows heat that is in the turbine wheel to travel up the shaft and into the bearing assembly. I will happily take some pics when i get back to AZ (after this round of east coast testing) to show you why this is bad for the turbo

otherwise, i have seen no other benefit to watercooling the turbo
