Blown Turbo

[frankyboy]

i changed my injectors from yellow to standered grey 1s i started the engine and blue smoke started

coming out the back. took it for a run round the block cos i thought the smokey exhaust was just excess fuel from changing over the injector but had no power but it was still boosting but just not giving me any power

any advice please

Why were you changing the injectors? Its not the best idea to drive on boost after changing injectors unless the car has had some form of mapping to correct the fueling.

the reason i was changing the injectors was cos i was advised to because the person who had the car before me put the injectors in never done any other mods apart from a HKS filter

so all i was doing was wasting fuel.

sounds like dodgy advice to me mate i always thought if you change the injectors then a remap was needed cheers

so you think the yellow ones should go back in again.

i dont think it was mapped for the yellow ones thats whats confusing me.

its defo not the turbo tho its something to do with the injectors

think im gonna throw the yellow ones back in see if that makes a difference

if the car was running fine before you changed them i would put them back in as the old saying goes if it aint broke then why fix it

lol i know but im a wee boy that like messing about.

but gonna put the old 1s in and let you know how i get on

the car runs an 8S ecu which is a standard uk ecu for years 97-98 same as my terzo which runs grey phase 1.5 injectors and which has a central coilpack and runs 0.8 bar of boost

Lets change the old saying to 'It is broke'

right just put old yelleow 1s back in and its still blowing blue smoke took it for a run in case it was just fuel in the cat

but still no luck

it seems fine just ticking over but after a couple minutes driving its starts getting smokey again

I would take that car to a garage like Hypertech and get Dunc to check the fueling on the rollers other wise you might end up with a large bill for a replacement engine.

only prob is really dont wanna drive it that far

would it come up on a computer.

to be honest knowing my luck its something so simple but embarrasingly wrong IE a pipe has popped of.

is there any set way the injectors go in

i have 3 number 2s and 1 number 3

i put number 3 in where a took it out but the other 3 i have just put in random spaces

[frankyboy]

just put all the grey injectors back in and to my surprise it has stopped smoking and boosting fine

only a wee prob is there is a burning smell coming from the exhaust dont know if its burning oil now

[Phil MC]

Have you accounted for all the rubber seals from both sets of injectors?

(I've just learned the hard way about how migrating washers can really ruin your day!!!!)

What other work have you been doing on the car? You been fitting exhaust sections? Just trying to think what else, less sinister than a malfunction would cause you to have smoke then a burning smell. What is the smell? Rubber, oil, fuel?

[frankyboy]

think i have sorted my problem im one cool dude lol

right the smokey and smell from the exhaust was from un burnt fuel on the cat

just bit the bullet let it run for half hour out side the house took her for a run on the m/way

smoothly no boost got back no smell no smoke. let her cool down then took her out again no problems what so ever

so thank you to everybody for there advice and concerns
