OP, you can wait 30-60s before you start moving, but after that, start driving out of boost until the engine temps stabilize. Then, you can boost happily. Letting the car idle until it reaches operating temps is bad for the car.
That is what my friend said several of his instructors said, that it is hard on the engine to warm it up for an extended period of time. (He is graduating Lincoln Tech.) All you need is about a minute in the freezing winter and to drive conservatively (NO BOOST) until fully warmed up. He told me this after my origional post. But I still wanted everybody else's opinion. But I must agree with Warrtalon, and other similar posts-ak47po(thanks for posting the Mitsubishi info sheet I never recieved one), and my friends advise personally.

it's simple : wait untill your RPM drop to 1000.
and then you go .no boost untill normal water temp. but if it's too cold wait little longer with the boost, because the oil warming much slover.
and thicker oil = higher oil pressure. just safety for the gaskets.../or oil sealers/
and if you sitting in 15 minutes,that is not bad for your engine ,only you waste gas. No brainer, that is why watercooled.... it's cool it self,like you sitting in the traffic.

How would idling increase trans/diff temps? None of those components shares any oil exhange with the engine's oil.

Perhaps he's thinking the warmth would transfer from the engine block to the transmission and transfer case housings, warming the fluids as well.

Alright, just like I promised, I have the manual here:

"To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your vehicle stand and warm up. Be ready to drive off immediately after starting your vehicle. Maintain moderate speed until the engine is completely warm. Remember, the engine performs best at operating temperature."

That stuff sounds like what you guys have been saying, but just not clear enough... It doesn't say anything about 30-60 sec, just says immediately

The important part is driving to warm it up, not worrying about whether you wait 30-60s or drive immediately. We were making sure you knew not to let the car idle until it's warm - that's a no-no.

I hope the realize that oil comes-up to temp a lot slower than water in warm weather, as well.

hmmm.. i warm up the evo until the rpm drops, or until i finish my morning cigerette

3 mins is good, it all depends on the outside temp. If its snowing, u need more than three

driving is better , just dont go about 4K rpm

Why is everyone putting in their opinion on how long to warm this thing up? There's a right way and wrong way. You've been told the right way, you have a scan of what mitsu tells you to do... End of story.

Got a good story though, back around 93-94 I worked in a stock room from 4am to 9am. It snowed about 1 foot from the time I arrived to the time I was leaving. I turned on the car while I was scraping ice and snow off my windows... and locked the keys in the car. That poor Geo Storm idled for almost an hour before I could get my spare keys from home.

I usually wake up in the morning and turn my turbo timer to 10 min and walk back upstairs and get ready for work, then i go back down and drive it like I normally would to work. Seems to me that I should'nt do that anymore though... The reason I dont like driving my car when it's cold or only warmed up for 2-3 min only is because it's really hard getting into 1st and reverse. Also, the tranny feels like really clunky when shifting.

I have an 03 and I let the car warm up for about 5 minutes every day. The car has 102K miles and makes 310whp and 295wtq with a couple bolt ons. Never had any issues! I think it's safer to let the car warm up, not only for the engine but all the transmission parts as well!
