Turbo timer for 4.2 turbo diesel nissan

The best timer is the one that sits behind the steering wheel.

Some insurance companies wont allow Turbo Timers.

Check first.

Just out of interest, if off topic a bit....
I believe that there are now intelligent timers that analyse the conditions prior to turn off and set the period accordingly. I guess they must be integrated with the enging management system.

I still use the even more intelligent (?) one behind the steering wheel. Mostly no delay is needed.

I fitted the Advanced Performance Centre model from Qld. to my 80 - works like a treat ,about $132.00 to your door .

Austravel,

I fitted one from opposite lock near on 4.5 years ago and it works atreat never misses a beat

I used the the kit from Jaycar (silicone chip) which has a temp sensor that you screw on to the heat sheild of the turbo so it only runs when it needs to. Cheap, effective solution. About $30 from memory but you have to put it together yourself. The advantage of that setup is you can mod it to do other funky stuff like keep your engine going for 10minutes when you flick a switch so you can warm your car up in the morning but still lock the doors so no bugger takes off in it etc etc. Then when the 10 minutes is up it stops the monitor and arms the alarm.
I had two of these now, one in my old Rocky and one in the Surf, the surf was a mongral to setup on because of all the electronics in the alarms, central locking, etc etc but it work bloody brilliant.
