Sounds like a turbo timer would be perfect for you, if it is worth it to you to be able to escape your car a few minutes sooner. Wiring them isn't too difficult, wiring to the ignition can be a little tricky. If you can install a car stereo then you can probably install a turbo timer, it is pretty much the same skill level. The major issue with a turbo timer is how well it will work with an alarm. If you don't have one then it isn't a problem, if you do, consult the manufacturer.

maybe this is a noob question, but what benefits would an n/a car get from a turbo timer.....shouldn't you have a turbo to necesitate a "turbo" timer? feel free to flame away!

Don't worry about asking dumb questions, that is how you learn, and learning is the purpose of the internet. If someone "flames" you for asking a dumb question, they shouldn't be here, if they aren't going to help, they shouldn't post.
On to the question, an NA would get zero benifits from a turbo timer...heres why: After a session of hard driving, a turbo car will become quite hot, and the oil will be quite hot as well. If you simply shut the engine off, directly after hard driving, the oil ceases to circulate through the engine (and turbo) because the oil pump is no longer running. Since the oil is no longer running through the turbo and taking heat away from it, the remaining oil in the turbo will superheat and end up "coking" the bearings. Coking happens in a turbo when oil gets too hot, it breaks down and burns, leaving behind a rough oil residue that is hard on the bearings. Water cooled turbo's resist coking much better than oil cooled, but it can still be an issue. Also, even after shutting the car off, a fully spooled turbo can continue to rotate for quite a long time, without fresh oil going through, this is very hard on the bearings as they rotate at high speed (turbos can rotate at speeds up to 250,000 RPM) without enough oil to protect them. The solution, rather than sitting in your car for 5 minutes every time after driving ( to let it cool a little bit and let the turbo slow), is a turbo timer. The turbo timer idles your car for a set period of time after taking the key out of the ignition, this way you can take your keys out, lock up and leave, without having to wait for the car to cool a bit. Basically all the turbo timer does is saves you a little time. If your car is NA, it has no turbo...No turbo, no point in idling your car to help save the turbos life...because you dont have one. Does that answer your question?
