Opel injectors

I went and got my car dyno tuned last Wednesday. I swore the guy I bought the car from said it had opel injectors. Tuner said the car had stock injectors in it. In the photos are these Opel injectors? They came with the car but not installed.

Since the car is already tune, is it worth installing these? I do not have HPtuner nor do I have the funds to buy it right now.

What fuel are you running and is it stock turbo? You don't need them on pump or e47 with stock turbo. No benefit. Bigger turbo, yes, but I believe you have to be tuned for them.

Sell them for present upgrades, or if you see a big turbo in your future hang on to them. Dont try to remove the injectors from the rail for any reason. Not saying you would, just saying. The Opels have a very delicate straw that will break off if you remove them.

I had a issue like this with my LDK, everyone says they come with opels that flow more but its just the E85 seals on them, they flow the same as stock LNF injectors.

Yep, opels will flow more than stock lnf injectors. There is a post somewhere in here about the difference.

I think what Royce was trying to say is the LDK doesnt come with Opels, just stock LNF style injectors only upgraded black seals

Would you need to upgrade to Opels if you were thinking of putting a 6258 on and running pump gas?

Not for a 6258 or a 6758 for pump. You'll be limited power wise but it will still be fun

6258 would be a ton of fun if you had a built trans. Heard they can hit full boost at like 2,000 rpm and still max out at around 400whp. 3,000-6,500 would be a nice powerband.
