is this normal?

not going to lie, i was highway racing and when i parked my car, i let it sit for about an hour then went to start it and it started normally then stalls, so i did it again and just started driving on it, well it eventually got to the point where it wouldnt stall but it would idle around 500-700, i do have the engine street ported, and at high revs the car does smoke a little bit, and it was cold outside, just wondering what the problem might be...........?

Ur car hates u.....no not really mine does that also. One little temp fix I found was to let it run after driving like it had a turbo timer. Allows the motor and oil to cool down and makes ur car like u more.

^ I Second That!

Its good to let your car idle a little bit before you shut it off, especially after racing. Even if you dont have a turbo

So its running rich. How old is the motor. n/a or TII? Check the injectors and spark plugs + wires. Start with the basic less exspensive stuff. Rotarys are known for running rich when modified, hence the flames.

Blown or loose hose...

If not, get a compression check done - this will confirm or eliminate the motor is hurt.

You did take off the cats along with the air pump right?

Also what color is the smoke you talk of.

your going to be running way rich with stock turbo and 720cc secondaries without taking some of that fuel away with an safc.

Blue smoke=oil leak into the combustion chamber.

Or its a rich running OMP.

I think that during your race the exaust gasses got so hot that they burned up the O2 sensor to its final stand. That could explain why your running rich..

Do the quick&dirty test...
Pull top spark plug one at a time.
Remove both top fuses under the hood.
Push down on gas pedal all the way down.
Crank for 10 seconds - note sounds of "pfffsssttt"
Replace stop spark plug and pull other top spark plug.
Repeat above.
They should all be consistent sounding.

I got a kick out of how you started your Intro...with everything mentioned, I'd do the simple but effective method as RETed has mentioned. This should give you a better status of your Engine.

i bet you were racing and blew an IC hose loose, still reaming the **** out of your turbo and blew the turbine oil seals.

the loose IC hose would explain the crappy idle, and the blown turbine would explain the smoke.

on either side of the intercooler, anywhere after the turbo and before the throttle body.
