so i just finished my headgasket, and i think the valve timing may be advanced a tooth. when i get on it, the boost goes up to about 20psi, it doesnt go up very fast, and it creeps to about 24psi. i even pulled the line off the wastegate to see if it was just the boost controller, but it still did the same exact thing. car runs fine and all, but wont boost very well. it almost feels like its at part throttle.

damn whats up with you blowing head gaskets ???

have you been using the same head all the time?

BOX SENTRA

i dont know, if this one blows im just gonna go with a mitsu metal layered headgasket.

JR.

ur blowing headgaskets because ur either not doing it right or ur runing to much timing on ur setup fool.

BOX SENTRA

ok well my question wasnt "why am i blowing headgaskets"

JR.

Advancing both cams or just the intake cam will bring the turbo on faster adding to the mid range power.
Advancing just the exhaust cam will add top end.

Check for a leak at the wastegate.

BOX SENTRA

ill check, now i did verify that the timing on the cams were off. i set the timing again and the boost does come on harder, but its still only hitting 20 and creeping to 24psi. ill check the wastegate and the manifold though.

Also check the bov for leaks.
