hello everyone, can any one help???

Ive finished building my zetec turbo, and when i first run it up it was fine, boosted up fine, loads of wastegate chatter , how ever the turbo blew its guts, the oil return wasnt good enough, ive fixed that now.

Ive now got another turbo on it, and it wont boost, ive pulled the vacuum pipe off from the turbo to the actuator so that should give it maximum boost??? Its a t3 by the way.

Can anyone help????? Thanks.

check to see if the wastegate is stuck open,make sure the actuator arm is on proply

zetecdan89

yeah ive checked those 2, im wondering if ive caused internal damage??

or maybe if the timing has jumped, could that cause ot to not boost?

is the engine runing lumpy/knocking?the turbo should still boost.have you checked all the vac and intercooler lines/pipes?make sure they on on tight

zetecdan89

its running a bit lumpy, but it was in the first place and it was boosting, checked for leaks, even bypassed intercooler incase it was blocked.

when it blew the 1st turbo, it made like a bang noise along with a big puff of smoke.

there is no such thing as wastgate chatter thats pub talk!!! as for the turbo are you sure the turbo you have fitted is in working condition??

zetecdan89

yeh its good, another thought i just had, although im running standard oil pump, if for some reason there was too much oil pressure would it just blow the turbo or could it prevent it from spinning up?

creator

the oil pressue shouldnt have anything to do with the turbo spooling unless its getting no oil in there,then the turbo will just seize up.i think.is the actuator set corectly?for the correct boost you want?

zetecdan89

yeah, its doesnt matter if the actuator is wound in or out, even a bleed valve dont make any difference thats why im confused. Do you know if i can get my standard ecu remapped or do i have to buy an aftermarket ecu? i only wanna run between 8-10psi

creator

what ecu is it on mate? was it a brand new turbo?

zetecdan89

nah the turbo came off a running escort rst, and do u mean what car is the ecu on?

Guess the actuator came with it as well, if not if you fitted it did you preload it first? Chipping your car at the moment will not do anything as no boost is being made.

yeah the actuator come with it, what do you mean preload it? even when the waste gate is held closed it still dont produce no pressure so i dont think it has anything to do with the actuator?

creator

yeah mate what ecu is the car running on? ofab/ofac?

zetecdan89

ive never understood that ofab/ofac lol, its a non pats ecu if thats any help

clarke5700

are you telling me you are running a standard na ecu?? with a fi engine??

yeah at the min thats why i want to know what ecu or what ive got to get next?

clarke5700

i wound go to m-tech or jamsport en get them to fit + map one of there aftermarket ecus tbh

zetecdan89

ok mate cheers for your help, do you know what thats gonna set me back ruffly?

clarke5700

£1000 at a gess

M-Tech Automotive

Thats a supply fit and map price with us of £995+VAT on our V4 ECU

I would go careful running with what you have, if its an NA ECU you wont be reading postive MAP and it also wont be retarding the timing!!!
