While I'm awaiting the arrival of my new turbos, I've noticed that the carbon seal has just about had it on the current rebuilt turbos. Upon startup, the smoke cloud is immense. Once the car is fully warmed up, the smoke stops and only reappears when the secondary is engaged (and only between shifts). I know the plugs are getting super-fouled right now ... what else should I watch out for? I have planned to replace all the coolant and oil lines. Anythine else?

 

Should I be worried about clogging the cat? Anyone?

 

With our cars running so rich at idle and me running race gas lotts at the drag strip... plugs can easily foul...

I use every 3rd tank of gas an ethanol based fuel.
Seems to burn a little hotter and keeps the plugs clean longer.

Gas with lotts of tolene in it will foul plugs more often.

And also driving in slower traffic. I try to get allot of free spirited runs with it quite often. This will help to keep the plugs clean too.

Get some at least some 9's for heat range.
