rob77 Posted September 11, 2003 Share Posted September 11, 2003 Is it worth getting them cleaned and tested for flow? If so who does it, I just rang united fuel and they want $40/injector and the guy (wayne or warren) said that 1 out of every 10 leak from the middle and they dont warranty that.

Gradenko Posted September 11, 2003 Share Posted September 11, 2003 Yes, if you've got easy access to the injectors its worth getting them cleaned and flowed. Mine were blocked even though it hadn't manifested in pinging or rough idle yet. I haven't driven my car yet so I can't comment on the difference, but I remember on SDU people were raving about smoother throttle control, smoother running and better fuel economy after cleaning injectors. I can highly reconmend EFIS in East Vic Park (as referred to me by Steve-SST). Don't know how much they charge to clean injectors but they were reasonable in fixing up a stuff up another injector place made with my injectors. I have a bunch of 25% off vouchers for EFIS that you are welcome to. Don't know if they're still valid though. What did united mean by "leak in the middle"? The middle injectors in the fuel rail leaking? Or some fault in the centre of a injector making it leak? EFIS pressure tested my rail once the injectors were back in and none of them leaked.

I havent really got easy access to the injectors still have the stock plenum in the way. I was just thinking it'd be worth pulling them out, cleaning them and checking the flow before I start leaning on the engine with the ecu tune. I think I might try these people, how/when can I get one of those vouchers off you gradenko?

rob77 Posted September 11, 2003 Author Share Posted September 11, 2003 As for the leak in the middle bit I didnt understand that either. Sounded like the guy didnt really know what he was talking about, eitherway, if steve reccomended the other guys I'll try them Link to comment https://www.sau.com.au/forums/topic/24625-injectors/#findComment-525469 Share on other sites More sharing options...
adam 32 Posted September 11, 2003 Share Posted September 11, 2003 i had mine cleaned and flow tested for $100. perfect results, car was nicer to drive, smoother, and flowed more fuel for higher boost applications Link to comment https://www.sau.com.au/forums/topic/24625-injectors/#findComment-525527 Share on other sites More sharing options...

Gradenko Posted September 11, 2003 Share Posted September 11, 2003 rob77, I'd be hesitant to remove the plenum just to get to the injectors. Pulling the plenum is an absolute PITA, so only do it if you have to. Unbelievably the gasket between the upper and lower plenum in $85 from Nissan. I think rev210 has removed injectors with the plenum still on, so give that a go and pm him if you get stuck.

ix9 Posted September 12, 2003 Share Posted September 12, 2003 Gradenko, You should try replacing the exhaust manifold gasket $127 from Nissan! and $5 for each stud! Link to comment https://www.sau.com.au/forums/topic/24625-injectors/#findComment-525801 Share on other sites More sharing options...
R32-GTS Posted September 12, 2003 Share Posted September 12, 2003 Its not hard to take the plenum off. Ive got my time down to 20mins to get it off. Makes its sooo much easier to get the injectors out. Just buy a new manifold gasket from nissan that costs 10 bucks.

Gradenko Posted September 12, 2003 Share Posted September 12, 2003 R32-GTS, maybe the rb20 plenum has bolts in different locations, but theres no way you're going to pull a rb25det plenum in 20 minutes. Just buy a new manifold gasket from nissan that costs 10 bucks. ?? Have you priced these for the rb25det? They're not $10.
