hahahaha. i got this thread beat. there was a guy on gtrc asking us how can buy PSI for his cylinders. its a long story but someone basically did a compression test on his rb26 and found low compression in some of the cylinders. so as a joke he asked people who wants to a group buy on compression. 99% of the people got the joke. one guy didnt. so he started a thread asking how and where he can buy PSI for his cylinders.
