I just had Billet design in south florida install my greddy tt kit and the car is still in the shop the turbo's have not even been boosted or driven more than half a mile, but the car has a serious white smoke problem ! the kit is brand new andd billet design knows how to install the kits your info would be greatly appreciated, oil and radiator fluid have been checked for leaks and clogs !

 

is that Bart Tobener's shop?

 

Are you seeing white smoke under hard acceleration? at this point my guess is it could be burning oil or just the water coolant. Same problem happen to my cousins Z with Greddy TT after first 1000 miles but, unfortunetly his was headgasket. But then again don't panic Billet design those guys are pros you should be fine.

 

I know squat about turbo's . But from other threads Ive read about the same thing . I would guess your oil return line isnt draining back into the motor and oil is backing up in the turbo

 

marco checked the oil return; and i have never taken the car out it started smoking after the install. billet thinks the seals in the turbo are gone but there brand new. Marco has checked all the lines, but there is oil in the turbos and it smells like burning oil !

 

Well if I were going to have a shop install anything for a G35 it would be BilletDesign.. White smoke is better then having blue like smoke! Oil will always be in the turbo which is why people buy turbo timers so when you park your car and get out it leaves the car on for 2 to 3 min to get the oil out and then shuts the car off for you. Did you have them dyno tune it? How much whp do you have?Did you do any internal work? Turbo set ups have blown so many G35 motors.. You need to be real careful..
