Late post but im putting together another rb for the drag season and have came across these pulsar turbos you guys maybe interested in, I have buddies that are beating the piss out of them on there jz's, they seem to hold up just fine and are 1/3 of a price of precisions. im currently on a 6466 but looking to make 900whp. im going to try the pulsar 7170 not even a 1000 quid!! good bang for buck
