Sorry im not the best with cars, The open wategate with no boost, what is obvious about that? that the Turbo is shot?DeleriousZ wrote: goddammit, i had a whole post written out then hit 'back' on my mouse and erased everything (*beep* IE at work)
anyway.
open wastegate = no boost, that should be obvious.
replace chts and its subharness.
fix your distributor.
recalibrate your tps… this causes idle and driveability issues.
was your car always a 5 spd?
fix the detonation sensor, it shouldn't be too difficult, it's either wiring or the sensor itself.
either fully disconnect your fuel temp sensor, or clean the connections and test the wiring.
DO NOT USE OR RE-USE OLD SENSORS you are just asking for trouble. get new ones from nissan.
Ya i believe this car was always a 5 speed.
Where is the fuel temp sensor? ill use my little book for that, chiltons or something i got.
replace chts and its subharness. What is this?
How do i recalibrate the TPS?
Sorry for being such a noob, im trying. And sorry about your deleted post that just sucks and thanks a bunch for all the help!1986 white turbo Z Current project

It should all be covered in your Chiltons or haynes manuel where and how to test these things!
Your car won't build any boost if there is no load on the car/engine.

basics: if the wastegate is open, less exhaust gas spins the turbine, therefore the turbo doesnt build boost… think about it like that for now, till you research it more..SS #341

uh, no, axial means 'along the axis'.DeleriousZ wrote:

if the leaks on the manifolds are bad enough (i'm unsure as to what is "bad enough" ) you wont build boost. or, which seems likely to be the case, you'll have inconsistent boost.
someone correct me if i'm wrong, but that might be a major cause of his car's ailments?SS #341

Car acted the same way prior to this exhaust leak, but ya, these leaks are definatly making it worse..Durkin wrote: if the leaks on the manifolds are bad enough (i'm unsure as to what is "bad enough" ) you wont build boost. or, which seems likely to be the case, you'll have inconsistent boost.

radial, not axial, my bad.

a bad enough exhaust leak will sometimes let O2 get in to the sensor thowing it off. you can also cook valves if i remember right. and no… you should not be able to open the wastegate easily by hand. check the diaphram in the actuator. if its leaking that can screw with consistancy big time. Anyone correct me on any of this, I am F^#&ing tired…'87 300zx vg30et soon to be et/er
