I just got my injector hats adapters for the RDX injectors I'm going to install into my b-series motor, now when I install the hats onto the injectors do I need to remove the hook on the RDX injectors to make it sit right, or just leave it on?

Anyone? I should just try one and report back huh.

remove it you can't fit the hats with the hooks on .

may i ask what fuel pump are you using with these injectors ?

Thanks for clearing that up, I'm not to sure I'm still doing my homework on fuel pumps, I was going to run aeromotive 340 but I'm seeing mix reviews on them.

What do you recommend?

get a walbro 255. cheap and effective

True but I'm looking for something that will flow a little more.

I'm running RDX injectors on my stock pump for a 99 GSR

Plus 1 on 255.

How much more flow do you need, more importantly what base fuel pressure are you looking to sustain and why? Stock fuel pressure or higher?

Well I thought the 255lph HP wouldnt be capable keeping up with these injectors, @ 38psi the pump will do fine right?

I was wanting to do 55psi for a base pressure to get a better atomization, which these come stock on the RDX right?

Now forgive me for be such a noobie I'm still learning, any info will help me, if the 255lph HP will fine on my bulid let me know, I have a freshly build motor with a CR 11:5-11:9, I thought these injector would work great, a price that can't be beat.

Btw I will post up pics of the hats on the injectors.

GhostAccord

255lph is probably a bit overkill, 190lph would be suitable to hold 55psi with a set of RDX injectors on an all motor B series build.

I though all this info was in another thread?

GhostAccord

This info is all over the internet if you do a search........All the formulas to calculate fuel pump flow rate in conjunction with injector flow rate are all out there as well. Some just need the air plane spoon every now and then.

i run 190lph + rdx injectors

i have a b&m fuel pressure gauge at idle i get 49psi and wot around 58psi
i know that these gauges may be a little off btw...

i would choose 255lph you get 70-75psi on these.

Where is the best place to get the hats for these RDX injectors?
Thanks,

http://www.xenocron.com/injectors-rd...s-c-30_98.html these guys are great to deal with and have a good range of fitment stuff for the RDX injectors.

FWIW, I usually clip off the hooks.

Do you have to extend the studs on the IM to install these?

OLDMNSX

If the aftermarket caps are made correctly the RDX injector with the cap installed should be the exact dimensions of your OEM injector, No other modifications required to the fuel rail or rail attachement hardware.

todahead

you can leave oem studs the nuts use a lot of thread but
just for piece of mind i used extended studs.

Nice setup, I actually just got the RDX injectors with the tophats as well, but they are not installed yet, waiting for my fuel rail. Anyway my question was after you installed them, how did they fit? And do you have a picture of them installed?

Thanks
Old or new I appreciate your reply, I am bow to install them in my B18 and I haven't seen any videos or pictures of anyone else that did this mod, i've known it's not a new thing and ppl have been doing the mod but haven't seen any one post it until I seen your post.

So thanks for replying..
