sr20det not reving out and dying out ???

hi

I have major problem with engine that i can not get my head around it. its a s13 sr20det 93 black top drift car. spec on car is standard ecu, injectors and airflow. boosting at .9 ~~ .car has walbro pump, fuel reg, intercooler,s15 turbo proper one :) straight throw exaust .
whats happing is
start car, starts perfect,ticks over 100% no noise no rattles or bangs.
car will take rev to about 5000rpm then die out. then start perfect again try to rev higher than 5 same thing happens again.
this is what i have done to try to fix the problem

swapped ecu+
coil packs+
airflow.
fresh fuel
new fuel filtr
new plugs
tested fuel prussure
changed injectors
checked turbo piping
knock sensor

all parts i have taken from my sileighty that i know are working
im thinking that could it be actuator not opening (yet to change) and check cat.

has anyone had this problem or any suggestions what it could be.
very greatfull for any help.
thanks
niall

yes so we see.. and said
and keep an attitude like that and you wont get any help;)

only seen comment afterwards! so any ideas. :)

when you say that it revs to 5000
does it mean that you've boot to floor and just wont go by 5000??
its it banging and spluttering when it reaches 5000 or just dies down???

yes when car is ticking then go to rev it it will rev to 5000rpm with no problems than after that it wont go any further makes kindoff noise like back fire then dies out completely. normally it would hit limiter. o and exhaust isnt leaking or anything.

Is it still running on all cylinders when it cuts out or is it missing on one then dying out, any noises at 5k rpm?

did you try a cam position sensor?, if you rev it slowly like 200rpm at a time will it creep up past 5k or the same happen

fuel cut????????????

that i am not sure .i have only checked when only ticking over by plugging out injector and coil on each cylinder.
i have changed all injectors and coilpacks and that didnt fix it either:(
how would you suggest testing them at 4500rpm just to be sure??
no noise at 5000rpm from engine internails.

hi yea have tryed that when it comes near 5k it starts struggling to run

:):) thanks very much guys for your help. if ye thing off anything what it could be please let me know :):):D website is great hope to get few pics up soon as possaible cheers

i have something like that wit mine only mine is dying out at 3000 rpm. will yours rev up when its idle? mine only does it when driving!!it will rev up perfect when standing still. its like the turbo aint working at all

sounds like its drawn air or or ecu hitting limp mode,, did you try turning back down the boost and c what happens

i had an s14 200sx at this b4 and it was the lamda sensor was fuked!!! but id put a guss at the lamda or the afm!!!

well richie
ya mine will rev perfect but after 5 it gets messy i think it could be waste gate not opening have a new hks actuator to try may solve it
what car you have?

its fairly impossible to diagnose a car without seein it dude, ud wan2 bring it somewher!!

i know its comming to that

but ill not give up yet it prob really simple and im over looking it
ill end up kicking myself over it:D:D:D:D

mine is a 180 lad i have the boost problem post up on it. i taught actuator wasnt working and it was stopping turbo from working properly but i tried mine today and actuator is perfect so im no further on either.

almost same prob im trying lamda senor this evning did your happen to run out off fuel?

it didnt run outta fuel but its like its being starved of fuel or something when its trying boost. it misfires and bacfires then comes right again when ya change gear or ease off the throttle

after hours off looking finnaly found it.
the wires that run from ecu to air flow meter have broke down replaced with new wires runnig perfect:):):):):):):):):):):):):):):D:D:D:D:D:D:D

dubble check your turbo piping anyway press on then the could be broken .the wiring was my problem aftr all:):)

wiring to the air flow meter was it? i didnt get a chance to do that with lamba sensor

dont worry about it got it sorted

what was wrong wit your wiring?

i done a resistance test on the wiring. the heat and over time i guess just broke them down. have you checked all you piping and squzzed them? i had the same problem a long time ago.double check you piping anyway my advice.

i got it sorted lad the jubilee clip had broke and left the intercooler pipe a bit loose so it was loosing it there. took ages to find it. i only let air out when it was under pressure

I should have read the last post before answering:rolleyes:
