Hi to everybody... I had started a 200sx nissan with an RB25 and for the beginning i will keep the OEM turbo!! The car has a Greddy intake manifold,infinity throtlle (90mm), 60x30x10cm intercooler,76mm pipes, metal head gasket,ARP head and rod bolts,N1 water and oil pump and the exhaust bore is 76mm!! I want to know what is the standart boost pressure that the car works,and what pressure can i give in order to keep the turbo safe?? Thank you (and sorry for my english)!!

stock is 7, turbo is good til about 12-13 psi. After that you risk breaking the turbo.
