i want to find out about my gsr head is it jdm or usdm? it said on the head is p72-2 wit a 93 on it and some other number. i was like wtf!! 93 gsr? doesnt have a p72 casting on it!! is it a jdm gsr head? if dats so....dat would be the problem cuz my car is slow and is bogg when i try to power shift!!!

 

For a P72 head, JDM=USDM. Remember that new cars are typically released in the fall of the previous year. So a head manufactured in 1993 on a 94 USDM GSR is possible.

'Tis true. My 94 GSR sedan #000005 has a 93 head casting being it was one of the first ones made so it was late 93 as a 94 model. And at school we have a 90 LS motor that has a 89 casting on it.
