so as some of you know my car is finally done. At start up we are getting alot of smoke, dont know if it is fuel or oil, but I am running bigger injectors with stock ECU until I get it tuned. Smoke goes away when car is warm the reason why we are turning on the car is to chck for leaks and to make sure everything is ok before we take it to the tuner. Here are some pics of the oil lines, let me know....

 

how much larger injectors are you running? 440cc will run on stock ECU with very little trouble. 550cc you might notice some bogging.

If it was smoke due to being rich, it would be black.

If it was smoke due to oil, it will be blueish white.

 

clouds of smoke black and white/blue.. maybe turbo needs to be broken in.. idk

750cc injectors

 

how in the world can the stock ecu, with no way to tune it, run bigger then stock injectors? your prolly flooding the motor with fuel, and can damage the rings from fuel wash i believe.

i woudlnt do this if i was you. get a base map from tuner and pop in your tuning soltuoin. then recheck these things. i am pretty sure turbos dont break in. did u forgot to remove the oil plug form the drain side of the turbo? that'll blow out a turbo seal in a heart beat.

where is smoke whatelse did you do to car besides turbo kit? block, head head gasket?

Its hard to see in the pics but did you put teflon on the drain fitting???

 

we put thread sealer.. not teflon

 

Seriously are you crazy, I would not drive a S2k with a turbo and no tune or aem/kpro to a tuner. Your next thread will be about a engine rebuild.

750's?! fuel wash! Your stock ecu cant account for the extra 290cc of fuel you are ingesting into your motor in closed loop --idle/partial throttle) it either gets burped out in black smoke or leaked down your pistons and eventually creating blue smoke which you do not want to see. Might be too late for your motor my friend. i would do a compression check. But check your oil condition pronto! I just replaced a motor due to being fuel washed, sucks. Your oil will be dark but thin/gray looking due to the fuel breaking it down and the metal marbling specs you will see in the oil from your piston walls/rings if its too late. Will smell like fuel as well. Stop driving it and change the oil right away.
