How do you warm up your Early 911 2.0,2.2,or 2.4
It seems like my 2.0 punched to a 2.2 runs best when I fire it up and immediatly rev it to 2,000-3,000 RPM's for about 45 seconds. I know that these early engines are the toughest of tough but I want mine to last. It was rebuilt about 15,000 miles ago and I want it to live a long life. Any tips? Oh and lets keep this a discussion of the early engines only 2.0,2.2,2.4.

2.4S here. I just follow the procedures in the owner's manual...
key on, wait a few secs for the fuel pump to presurize everything. Then pull up the hand throttle & turn the key. It usually starts right away. If not, I'll depress the gas pedal a wee bit. VRoom... Then I leave the hand throttle up. In a few minutes the revs will build naturally, telling me it's okay to drive. Then I push the hand throttle down. I try to keep the revs low, under 3,500 when driving, until the oil has warmed up.

Don't rev it up, start it and let it idle. The oil is cold and thick and if you spike the oil pressure right after you start it it could cause trouble, particularly if the engine thermostat isn't closed all the way (in the recirc position that would send high-pressure oil back into the case and NOT through the oil cooler). Also, as an aircooled engine, you want to wait for everything to expand from heat to make sure the clearances are right before you load it. Finally, as a carb'd engine your 2.0 is'n't going to idle great until it's warm, so just let it idle, you will do less damage.

2.2E, here.
I start it and set the hand throttle for about 1500 RPM. After a few seconds (depends on outside temp) the RPM will start to climb on its own. At that point I stow the hand throttle and drive using the oil pressure as my RPM limit - it's an excellent indicator of the oil's viscosity and keeps me from exercising the oil filter bypass.

There are other lubes in the car that don't warm up with the engine. After the engine runs smoothly for a few seconds, drive conservatively to get everything up to operating temperature.

 I do that too.The one thing I have heard, and it seems to hold true, is that it will take the air cooled engine a LONG time to warm up at idle, so it needs to be driven once its warm enough to run smoothly.
