RB25DET problem

[Villa25]

I have an RB25det on my S13 and it keeps on acting up. everytime I drive it now and i rev it a little high, it bogs and then if I don't catch it.. It dies instantly. Can anyone tell me the problem. I got some ideas from other people that it's a cam sensor problem or it's the timing. I just wanna make sure before I do anything. thanks.:hs:

how high up in the revs does this happen ?

are you running a open BOV

Could be a bunch of things. Boost leak, sensor problem, etc. ECU throwing any codes?

if you have the Nissan diagnostic connector, check if its throwing codes. if you dont have one, i recommend getting one, as it will help out in figuring out whats wrong with it and future problems. but i had this problem before, and it was a vacuum leak. could be other, just start from the simplest point...

are your injectors even spitting enough fuel? not likely but its always possbile. where did this motor come from?

ok do you mean that when you rev it high it bogs down cause i have that same issue with mine and the problem is that the rb tends to lean out in cylinder 6 and it begins to knock and that bog you feel is the knock sensor shutting it down it could also be that 1 or 2 knock sensors came loose and it would cause the same thing that would be my best bet
