1G 2g injectors in my 1g

[Sbgriffin]

So I'm new to the forums, but have used them to search info for my 1g build. Have an issue that has me stumped. I know you guys don't like rehashing old threads, so I've tried my best searching this issue first. So recently I started having a stock injector fail on my 91 talon Tsi. After doing a lot of searching for a used set to replace, I decided to go with a professional cleaned and flow tested 2g injectors. After installing them with all new seals, upper and lower. They run great til they get heat soaked. Then I'm having a hot start issue, where I have to crank the engine excessively. So I figured it was low on fuel pressure after getting warm. So I put a fuel pressure gauge at the filter. All seems pretty good, 38 psi with the vacuum removed. About 30psi at idle with the vacuum hose on. I'm wondering if the 2g injectors work best with the higher 43psi on the 2g cars. It's like they don't have enough pressure after getting warm, yet my fuel pressure gauge holds pressure for about 20-45min. Any ideas? Thanks in advance.

Reach out to the seller and see if he can credit some money back. Your not getting what u paid for.

Removing just the lower honeycomb is not enough

Yeah I know, but i don't have another option right now. It's not my daily driver. I'm saving up for link, and buying a 2g maf soon. I'll keep an eye on it. It's actually idling better than it was, and It isn't fouling plugs. We'll see, I might be eating my words. But it doesn't seem to bad.

Yeah you were right. It's fine til about 4000rpm, then it starts breaking up. Live and learn I guess.

So I went ahead and purchased another set of 450cc injectors. Decided against running at all with the 550's. I'll sit on them til I get link.
