Moving car from street --> driveway: warm up or not?

Moving car from street --> driveway: warm up or not?
Hey gurus, for a super-short trip, something like 50-100 feet, would it be better to just drive the car cold for a few seconds and then shut it off? I know a lot of wear takes place while the car is still cold, due to clearances being out of whack and seals not being lubed well and jazz like that. So rather than spend a few minutes with the engine cold waiting for it to warm up , wouldn't it be better to spend 30 seconds pulling into the driveway/garage and then shutting back off?
I know this isn't exactly the type of subject this forum usually discusses, but it would be nice to hear some others' perspectives on this also.

Nope, since the cold start mode is very likely to flood the engine. Let it warm up or push it. When I drop my car off at the body shop next month I plan on paying the extra $150 "non-runner charge" and letting them push it around (I'm taking the ECU with me). The thought of cold short runs really scares me.

I normally start the car, make a lap around the block, put it where I want it, bring the RPM's to 3000, then shut it off.
Takes all of 30 seconds, really. Cheap insurance against the engine flooding.

I have started my car so many times and moved it the other way real quick and shut it off and never had any issues with it, the only time I had issues like that was with my FB with a carb, but with both my FC and FD never had those issues, well who know maybe I just got lucky...

I agree. The only time I ever had flooding issues is if I try to start it a couple times and somehow manage not to start it then let it sit a few minutes. I never had a problem moving the FD from street to driveway.
I am a firm believer that 99% of FD owners are overly cautious about certain things like this. All these little things they do add up to alot of time spent trying to increase the longevity of their motors but in the end they last no longer than anybody elses. It is a car, treat it like one.

If your car is flooding like that, you have a problem period. Internal combustion is not a mystry. Fuel + air + spark, the only time you would have flooding is too much fuel, no or low spark or a combination of the 2. So if you are having flooding problem, fix it.
The warm up thing is to avoid overloading the engine before it reaches optimal thermal equalibrium, causing premature engine failiur due to differences in the thermal expnsion properties of unlike metals present in every type of engine. It is more important for us beause the FD is pushing a lot more power per unit area (engine size) than any other car on the road.
We all love our cars, but this is paranoia. If you plan on going WOT and boosting 10+ psi traveling 100ft fron the street to your garage, than by all means, warm up the car.

I don't believe that you need to warm it FULLY up to operating temp - just go around the block really quick and get a little heat into the motor.

my fd has flooded 3 or 4 times now. it's only done it on pretty cold nights (below 50*) but doesn't have much trouble when it's warm. i suggest if it's colder where you live, to let it warm up. the ecu allows for more fuel when the motor is warm and could cause quite a headache

I've had the flooding problem several times on 2 of the FCs I've owned. This week was the first time I didn't take a lap around the block prior to putting the FD into the garage. I'll see how it does tomorrow after sitting for a couple of days.

actually thats not a rule at all. i can just imagine you sitting in your garage for 2 minutes waiting to move your car into the driveway. my fd has never flooded ever, and i don't think it would if i started and stopped it all day. do you think the rx-8 has guidelines to starting up the car in the manual?
