LDK Opel Injectors

Last July I swapped a full LDK in my sedan. LDK came with everything on it (turbo, coil packs, intake mani, injectors, etc) So I was told this LDK had the opel injectors. My tuner said from looking at my data logs my car does not have the opel injectors. I know everyone is gonna say just pull off the intake mani and pull them out and look. I plan on pulling the intake mani this weekend now that the weather is going to be decently warm. So my question is, is there any way to tell without physically pulling the intake mani off? Also if I do pull the intake mani off do I physically have to pull out the injectors or will I be able to look at a part number on them and know?

LDK engines had LNF injectors and white seals. LHU engines had OPELS and black seals (this is the reason I went LHU for my engine swap). if your tuner knows what theyre doing and they say you have stock injectors id say you have stock injectors. when I did my swap, for kicks I left my injector settings alone and did a datalog and my trims were all wonky, pulling lots of fuel. when I changed my injector constant from .028xxx to .025xxx my trims were much closer.

you might be able to get under the car and pull the foam away from the fuel rail to get the part number that's on them. they'll look the same other than the part number stamped on them. here's a pic of my LNF injector (fuel rail end) I took when I did the seals on my car, a month before the engine blew.

Thank you!. It was always my understanding that the LDKs had opel injectors. My tuner definitely knows what hes doing. I do believe him I am just thinking too much into it.

I looked up injector part numbers for LDK and LHU engines once I heard the LHU's had Opels. The LDK/LNF injector was the same p/n and the LHU was different.

..

Don't remove the Opel injector from the rail if at all possible. There's a little straw type tip on the end, like above the blue o-ring in the injector in the pic on the Opel's. They break very easy. Guess its anyone's guess if a new Opel injector/rail assembly has tips already broken inside or not. I was very careful pulling mine out and they still were broke. Don't know if I did it or not. There's a bit of a debate as to whether it makes a difference or not . ZZP says it may cause high RPM misfires. Some say it doesn't. Strange thing is the LNF injectors have no such tips.

I really don't plan on pulling them out. I would like to try flashes idea of looking from underneath. if not I think I have enough proof now the car doesn't have opels.

Thanks for the responses everyone

I saw the same thing. I guess the part I don't understand is that everyone calls them opel injectors but these arent the ones that "flow" more. So apparently it seems there is two versions. But my questions is are the seals on the ones I have e85 safe?

weird... best bet is to either message the person you bought it off of or post up your tune.

I bought it off mongo and he states they are the same opels ZZP sells. Which ZZP site states they flow more. Mongo told me he used they on his car with e85.

my tuner is KMO43 which im sure he will chime in soon and state that my logs were spot and on.



From all this I am gathering that they are NOT the ones that flow more but I do imagine the seals are e85.

basically what flash said is true, the LDKs just have the better seals not the higher flowing opels

Wonder what I have then.
ZZP sent me the engine, but some how didn't know what was in it.
Matt went to tune me for it, after putting it in, and asked me what injectors it had in it.
Asked me to call the mechanic putting it in, to see if it came with injectors.
The engine they sent had injectors, so he said it must be the opal then.
So, really I have no clue what's in there for sure...
For some reason I thought the people selling me the product would, but I guess that was just silly of me.

I believe they sourced the engines from europe, so opel injectors make sense. They used to send the blocks without injectors. Either they quit caring or this one fell through.

well if you got it from ZZP im 99% its the same place mongorat sources his LDKs. So I would imagine you just have the ones with the better seals no the better flowing ones. Your tuner will be able to tell if your fuel trims are off if they are the true higher flowing opel injectors.
