I have a 1991 GTR in the states and i am trying to defeat the octane problem. Fuel additives are no good, so i am looking to buy in bulk, the easiest solution is to buy leaded race gas in bulk. My car has upgraded turbines, no cats, and an HKS F-con VPro EMS. Is it possible for me to run leaded fuel like this, or what would i need to do to run leaded fuel. Thanks

Some modern O2 sensors have problems with leaded fuel, Iv never seen it myself, but I have heard from enough people who have to believe it.

The R32 is from the right generation to suffer from it, and I wouldn't recomend it, unless you have lots of spare sensors.

I forgot, the car has been changed from a mass airflow system to a MAP system would that help any?
