If you don't want to bother with the water lines, you could sell it for more than you paid for it and get a similar size t3/t4 turbo. It would make fabrication and parts location a little easier since t3 flanges and downpipe flanges are everywhere.

A turbo timer would still be good. Or just don't boost it the last minute or two of your drive and let it idle for about 30 seconds to a min before you shut it off.
