Something is seriously wrong with my car...please HELP!!!
So I have not been able to build any boost since i installed my turbo kit. For some reason my car is running super lean at WOT. (By super lean i mean 14 and up!!) I have tried adding fuel VIA emanage to no success. I have upgraded to a walboro 255lph pump, but i did not change any of the wiring. I just plugged in the new pump. Could this be my problem?? I am completely at a loss here. The only reason i can think that i am not making boost is because the car is running so lean. I have checked for vacuum leaks, and my turbo is getting oil and spinning freely.
the car....
1992 sc300
1jz swap
t61 single turbo
mkiv 550cc injectors.

It certainly sounds like a boost leak to me. Try checking your couplers too, a friend's WRX looked all fine but had a crack in the back of one of the couplers that you couldn't see at a glance.

wastegate is not stuck open, however i think i might be leaking around it. Would the vacuum line cause no boost? I was under the impression that the vacuum line would cause a boost spike.

i'm with everyone else, even though you say you checked it
sounds exactly like when my coupler blew off. . .
but iunno how you'd miss a leak like that if you put a cap at the throttle body, and then compress air into it at the turbo. . .
i don't think a manifold leak would cause 0psi at high rpms.
and a wastegate stuck open would make the car much louder. . .
