I'm looking for top feed injector holders from an 84T or another alternative that will fit my RC engineering 750cc injectors. What has everyone done here when switching to top-feed? Also Im using an 84T rail.


SATAN: (2007-03-26 02:33:45)

Thats pretty much it there. However, why are you using the stock rail with big 750cc injectors?

The rail can supply enough fuel, as can the stock lines, so I didn't get a custom rail made yet. I just don't have any stock top-feed injector holders and need to find some.


SATAN: (2007-03-26 03:29:31)

I wouldnt think that the stock fuel rail would be able to come close to supplying those injectors to their max capabilities. You can squeeze about 450-500whp out of the stock rails but that is pushing it.

make me an offer, i have several sets.. but keep in mind, jason is in the process of making rails. i dont know what his progress is right now. it may be worth it to wait.


Jason84NA2T: (2007-03-26 12:27:01)

Are the injector hold-downs different? I dont recall.

I should have pictures to post in the next couple weeks. My machinist buddy's father unexpectedly died, so his life was in turmoil for the last month or so and I didn't have the heart to bug him about some stupid work-related stuff.

I might be able to tap some sets NPT instead of AN so you could use hose barb fittings if desired (way cheaper). 5/16 hose will support over 500bhp, but I'm not sure about the rails because of the smaller ID.


JAMESZ: (2007-03-26 23:28:40)

If I can get some made that are a bit bigger I would be happy. I should have the capabilities with this set-up to make over 600whp, but I haven't found anyone in my area to trust in making new rails and the only ones I've seen from the Z community were 1sickZs and I stayed away from that.


SATAN: (2007-03-26 23:33:59)

Yeah Jason is in the process of making some, and if they are like any of his other products they will be good quality. I made my own and have had people ask me to make them some but I just dont like you guys that much :P

JAMESZ: (2007-03-30 18:44:48)

Yeah, I kind of need them now, and then I still need the holders. I guess I'm going to look around to try and find someone to make a pair.


Zen: (2007-04-02 07:50:10)

I wouldn't mind having a fuel rail made that accepted the stock or mercedes injectors


JoCkeWe: (2007-04-03 21:45:59)

Jason -> Send me a PM as soon as you have a set for sale! I'll definately buy at least one set If I haven't made my own by then. :P


Glennz: (2018-04-13 03:44:45)

Are there any upgrades to ECU for these injectors


NissanXRMA: (2018-04-19 16:47:11)

Tuning software is required to increase the fuel injector size, yes.
