Does anybody know how many pounds does the 2jzgte comes on from the factory? I've heard 8,10, and 11 psi IdK which one to believe. I've searched the specs for the motor but havent really found anything boostwise I wanna know cuz according to my boost gage im @ a little over 7psi, like just under 8 and IDk if I have a leak or im sitting good on the OEM setup. Its nothing with my performance, the car pulls pretty good but I just wanna know if Im leaking somewhere. Any help?

Aight thanks. that's still low for mine then if thats the case, Would you happen to know how to check for a leak.. somebody told me there's a way to check it with compressed air?

mine had 9psi, and i uped the boost by doing the bleeder t mod. which uped the boost to 15psi. try it and then make sure the boost increases, if it does dont worry about it, if it doesnt, you definetly got a leak somewhere.

97supraturbo.com is a great place to look for leak diagnosis
