Sell it and put the money aside into your 7" diff conversion slush fund.

Mapa, you can do a little searching and find that turbo-timers are a ridiculous ricer waste of money.
I know what you're thinking... "My BFF haz 1 in hizz CiviX 'n when he turnz off da engine, it keeps runnin and coolz off the turbo." Is that about right?
Back in the 80's, when OEM turbocharging was in it's infancy (not going to count Corvairs or 2002's), people discovered that if you got a turbo nice and hot, then shut off the engine, there was a propensity for oil sitting inside the CHRA to cook a little bit... over time, this would lead to premature oil breakdown and reduced oil (cooling/lubrication) flow through the CHRA... leading to premature turbo failure.
The progress in modern oil technology (and water-cooled turbos) and the universally (almost mandatory) recommended use of synthetic oils in turbocharged vehicles goes a long way in preventing this type of premature breakdown should you be the guy who boosts to redline pulling into his driveway and immediately shutts off the engine with a still glowing-red-hot turbo. This is a bad idea, but not as bad as it was when using mid-eighties dino-oil.
A turbo timer might be a good idea on a track car if you have to take a **** really bad. You can come screaming into the pits, jump out, run to the bathroom, unload that super-size helping of track-nachos that seemed like a good idea an hour ago, and come back to an engine that has had a proper cooldown from track temps.
However, pulling into a parking lot somewhere, or coming down the street to your house, turning off the key, and getting out of a car with a still running engine while you walk inside is ******* stupid... and completely unnecessary from any sort of "cooling" aspect.
