I have the option of buying some 750cc injectors and was hoping someone might know a little about them and what they are worth. These are later style OEM injectors that have been modified. They have the 750 inscribed on the outer casing. I haven't seen this before and wondered if anyone can tell me anything about what is done to modify them and whether or not they are any good?
Not a fan of high flowed injectors. If you want 740s or similar keep an eye out for second hand nismos. It's also worth considering that any variation in flow rates (between your high flows) is going to cause an issue unless you're running a standalone ECU with 6 injector drivers.
They should all be within a few CC of one another -you could always get them flow tested prior to install (or prior to completing purchase). But yeah good injectors come up at a reasonable price from time to time, to me it just seems the wrong area to be saving money. If they're an OEM injector that has been high flowed to 750cc you've nearly doubled the flow rate, essentially by enlarging the holes in the cap. I'm guessing you want something to match GT2860RS size turbos? Keep an eye out for 300 degrees rails and Nismo 740s, can't go wrong.
They are for GT2560R turbos. Wont be running big boost as it's not a forged engine. I picked up this engine to replace mine https://www.facebook.com/photo.php?fbid=839452956117553&set=gm.737947572975694&type=1. It currently is still running the stock TT injectors. I just found out that these 750CC injectors are originally from Emiles build so I should be able to find out a bit more about them at least.
Turns out they are Emiles old injectors, passed around a few new owners since but never actually used. So only kms on them are those done in Emiles car which from memory wasn't very much. He purchased them from CZP.
Note that you'll need different connectors for jecs injectors, they're either Nissan phase 2 connectors or Sard type, not sure.
