550cc nissan plugged denso injectors in 7MGTE??

Hi all,
Hoping for a bit of expert advice here!
I currently have the opportunity to grab some 550cc denso injectors for my 7MGTE at a bargain price. The dude selling them says that they just came out of a MK3 and that they fit all the 7M hardware perfectly however the plugs are the standard Nissan type and all that is required is new plugs which are an easy mod to the standard injector wiring.
Is this likely to be true? If new plugs is all that is required I'd save a lot of money buying these and they'd help take the (financial) sting out of the lexus AFM I just paid for....
Thanks in advance

ok.... so what kind of fuel pressure do you run through the 440cc units? (and what pressure through 550cc just for a comparison)?

if they are the correct impedance then buy them.
Make sure it wasnt on a 7m running aftermarket ecu.

Lexus AFM was from same guy. He wouldnt have needed the AFM if he'd been using an aftermarket ecu would he? Thanks for the replies guys

If it was the same guy, from the same engine, then you are correct.

Thanks blacksupra, put my fears to rest, these injectors will go lovely with my new apexi s-afc and walbro fuel pump, as well as the AFM of course!

About a 30 - 45 minute job.
Try and have the tank fairly low on juice as it makes life much easier.

Well, 550cc sards, safc and dyno being done at SAS over the next 2 days, so I'll be that much closer to finished after that. Your setup looks pretty similar to mine, what sort of power you making there?
