ok so i have a friend who has a built GSR motor and a gready turbo kit on it the motor has 250 miles on it and it has already blown the headgasket on it i have no clue what went wrong on the motor it was assembled by a well known mechanic any one have any idea what could of happened.

 

what makes you think its a headgasket?

 

the oil is milky compression test seemed low to me it was at 152.

 

was it an oem gasket? if the head was not torqued properly youll have the same symptoms..

 

compression could be to high. common with a gsr turbo. people forget to lower compression when they go with boost. i had to friends that went through that. one with a gsr and 19 lbs, another with a d16z6 and 12 pounds. so check that compression. peace
