Fuel Injector ID???
hey guys, I was just wondering if anyone would recognize the make of these injectors, they are low impedence 720's. They have a little symbol that looks like the letters "N" and "D" inside a small circle, could that be Nippon Denso??? Are Nippon Denso the supplier of GReddy Injectors? Thanks

well these are the numbers printed in the plastic:
1st injector - 45011, 25, 0, 331, 195500-0474
2nd injector - 23250-45011, 621, FF, 20, 0475
and like i said they both have the ND emblem as well. I'm looking for the reciept for these, they did not come with a flowchart.

This link is to Witchhunter. Has quite a bit of injector info based on the numbers/brands etc.
I would have them flow tested to see what they really flow. Most of us have found that at 43psi you will get higher flow than they are rated.
i.e. I have four injectors from the RX7 GSL-SE. They are rated at 680cc but they flowed 704,712,722 and 724cc respectively after cleaning and testing at Witchhunter.

yeah, thats what i',m thinking, they might have been drilled out. If done right is that okay? I mean can u actually drill them out to have them flow higher? i emailed the seller we'll see what he says... I ahve seen those GReddy ones with the blue tops, I'm thinking about just buying a set of four of those to be safe.

I've bought a few injectors from TLF...
The first batch I got (2) 720's and (2) 1000cc's all came in the same box, but during shipping they shifted around....he was able to tell me which was which when I phoned in the numbers - but when I talked to a friend of mine he said the ND numbers were for 400somethings and 180cc's.................so I believe thats a common occurance with TLF. I think its what they do, meaning buy used regular sized injectors and rebuild them for greater flow.

Yeah i just got a respinse back, good timing too. Thats what he said :
"Venom takes core from the Manu. and then puts their pintail in them to get the Desired cc's from them...."
So yeah the numbers on the TLF 720cc's indicate that they started their lives as 185cc and 190cc injectors. Thats alright by me as they look nice, they are solid and seem to be well built, we'll have to see how long the hold up.
Classicauto, how has your experience with these injectors been, anyone else used TLF injectors???
Thanks for all the help guys..

cool, neat to knwo these injectors have been brought back to life to fuel our beasts. I plan on running 720cc's all the way around, with the Rtek7 2.0 to handle fuel management. I want to run an aftermarket pump and FPR but can't find a good write up and how to install simple fuel system. I don't want a parralell fuel system, just new steel lines and FPR to hold psi for new injectors. Any info would be greatly appreciated.

making progress
So I just removed the throttle body and upper intake manifold to got to the fuel rails. I was planning on just seeing what was down there, but now I can't decide whether to just install the 720cc secondaries for now and try that or if I should order the other 720s and redo the hoses in braided steel or new rubber lines.
I'll probably just install the 2 720 as secondaries for now and then redo the fuel system when the turbo is upgraded in a couple weeks. Thanks.
How do you guys connect the walbro 255 to -6AN lines or can you use factory lines up to firewall and then upgrade all fuel lines in engine bay. Sorry for babbling but i'm just trying to figure out what to do for now.

Most people just use the stock lines up to the firewall and then use braided from there. You can either flare the stock line, solder/braze/weld on an AN flare, or (yuck) just clamp the braided line in place.
