duff injector?

tmschriscamper

it looks as if it is rich on all four cylinders all the plugs were wet

Let's do the obvious question. Is the new engine you've fitted from the same type and model year of car as the one that came out, and did you fit a full engine - complete with manifolds, injectors and so-on, or just a short/long build?

tmschriscamper

i got a engine from what was supposed to be a rear end rite off the engine was complease but im starting to doubt if it is a mach set of if someone has thrown it together it looked pretty good although im new to theseim let to belive they should be the same but i couldnt use the ecu as it had an immobiliser which the bloke didnt tell me about it had everthing else all injectors coil inlet manifold so on

Without wanting to sound like I'm taking the p*ss, can we have a bit of punctuation please? Making your posts more difficult than they could be to read means there's less chance of you getting the information you need.

Anyway, all that said...

What you've been led to believe and what the reality is aren't necessarily the same thing. For example, if your old engine had 380cc injectors and the new one has 440's (or bigger), that alone would explain the overfuel.

Seeing as you're new to all this, the easiest thing for you to do next might be to take the car to a Subaru dealer or specialist and get them to look it over. Beyond that, if you can make a note of the engine type you originally had (it'll be on the plate attached to the nearside suspension turret), and then try and note the type of the new engine (should be on a barcoded sticker attached to the centre cam belt cover), and post them up here, that'll help us work out what you've got.

If you can't see the numbers, it'd help us to know what model year and type your car is, and what MY/type the donor engine came from.

ok thanks very much
will try with the punctuation and spelling to.
will have to try and track down some info as my old engine has long gone.
i have got identical ecu number from both cars if that helps but am not shure how to tell the differnt injectors apart

thanks again speak to you soon cheers

if it's a classic checking the injectors might be as simple as looking at the colour of them.

the 380cc injectors where mostly a grey/green colour and the 440cc yellow.

you can probably see them just popping your head under the bonnet. if you where closer i'd have a look at them for you.

also have your reset the ecu since all the changes ?

tmschriscamper

not shure how to reset the ecu i did leave the battery off overnight but no difference

You don't need to track down the old engine to determine what type it was. As mentioned earlier, it's stamped on the vehicle ID plate on the nearside suspension turret - at least assuming the engine that came out is the original one. Look for a code that begins "EJ20....". Similarly, that barcode sticker on the cambelt cover should have a code that begins with EJ20. Post them both up if you can find them, that should help, along with the Applied Model code from the ID plate.

If both cars had exactly the same ECU part number, that should mean that the engines are the same, but your experience suggests otherwise. Can you see what colour the injectors are?

tmschriscamper

hi i calnt fina the sticker from the cam covers and there are no id plates on the car
i got the number from the casting above the startor motor wich is 932347
the ecu number is
6v
22611 ad370
a18 000 d40

and the injectors are alloy wasnt a coulour on them
and what isnt helping the hole manifold has been sprayed

is there any outher way of identifing the engine most stickers are missing as i think its was jet wased when removed thanks chris

tmschriscamper

i have managed to find the injector numbers now they are
r
--522aa400
a46701r70

l
17523aa35
702r70
is this any use thanks chris

Location of the ID plate in the pic below, it's on the strut top.

Did you fit a turbo long engine, including inlet etc?

tmschriscamper

vacumm pipe off or leak would make it rich.. dump valve open, intercooler pipe leak etc..

fuel supply plumbed wrong way around..

hi the engine runs but only for a short time and seems to smoke a bit and the plugs are wet wich makes me think its over fueling the engine is a 1996 ej20 none turbo have checked all vacume hoses and stuff and have replaced the air flow meter still wont keep running until i rev it
