When I lived in the Rockies (negative overnight/morning temps) I warmed my cars up for 5-10 minutes everyday. Partly because it can be tough to reach operating temps when it's extremely cold outside, and secondly because I like my car warm when I go out Anyway, I think that if you live in a very cold area let her warm up to operating temp while sitting there. If you live somewhere where it's not as bad (Tucson, AZ, for instance ) I say just keep it under 3k-4k until you get to op. temp.

 

It's always good to warm up your car until at least the automatic choke is off (the idle is normal) which is almost always normal operating temperature.

That's kind of impossible though, I mean, do we all get up 20 minutes early to start our car so it can idle for 10 minutes? No.

I just turn mine on, go back in and brush my teeth/comb my hair and come back out and get in the car and drive. That's all.

I'm in California, it's rarely ever below 45F when I get in the car. and its garaged.

 

a general rule that I have always followed with any of my cars is that when the temp gauge raises up to where the "C" is (as opposed to sitting down below it), then I'll go. If the car is totally cold, that takes about 5 minutes.

 

in gs-r's, everything functions normally once the temp guage is above the "C" line. so i just waited till it got there.

 

It isnt good to let it idle for a long time, or until its fully warmed up.

You should only idle it a bit, then just drive very conservatively to allow all the moving parts to get lubed properly and remember what their job is

 

this is exactly what i do.

 

Are you guys/gals sure that VTEC doesn't engage on the B18Cs until the car is warmed up? I know that the new RSXs won't go past 5k, because there's a cold temp revlimiter. I've never tried to rev mine into vtec when the car was cold and probly won't, but can someone let me know if it's true?

I am almost 100% sure, for the oil circulation reasons I stated above. Note that this was info I read from somewhere else, not my own personal knowledge of the b18c or anything.

One time in HS I was in a hurry, so I cold-started my car and hit 8000 rpm pulling out from my parking spot. Didn't hear the secondaries kick in at all, and I felt ultra slow (not to mention ultra stupid as my car made a lot of noise and didn't go anywhere). I highly doubt the vtec cams would be able to kick in if your temp was pegged at C.

Yes, 100% sure.

It wont engage until it's warm because there's not enough oil pressure to make it engage.

So you can redline a GSR without VTEC kickin in? That does make sense. I have herd of people not having enough oil pressure when trying to redline and the rpms just dont go that high.
