HOPE THIS IS POSTED IN THE RIGHT AREA... I drive a 93 Rx7 FD.. Looking to upgrade my secondary fuel rail and going up to 1600cc+ secondary injectors. Probably going to go with radium, but I was curious what else I'd need or if what I purchase from the site will have everything I need to just bolt it on (excluding injectors). I really just wanna do this right the first time and not have to deal with any BS. Thanks in advance.

 

If you need the added customization of radium then go for that one. I have this basic secondary and the injectors that are available with it. If you are still on twins there is a bit adjusting needed but not too bad.

if you are going to go with the "exotic" radium rails i wouldnt even consider the 1600cc injectors option. go with the 2000s

 

Well if I'm doing that then I'm doing the primaries as well, thanks for the input

 

All of the Radium gear that I've put my hands on has been awesome and completely fully outfitted with extra bits such as fittings, fasteners, etc.

 

I recently received my radium gear (I’m in Australia)

i got the primary and secondary rails, FPD, regulator and guage and acv block off plate,

the reason i went with them is the secondary rail has the option of 4 injectors if i need to go that way later on, (I’d rather 6 x smaller injectors that 4 huge injectors) and it came with all the fittings, fasteners and everything i need, plus they look awesome.

price was another factor, the CJ rails look awesome, but were a little too much for me, and as for other kits, well, yeah they work but for future upgrades (like and extra 2 injectors if i need them) I’d be spending $$ twice!!

then there is the “copies” that are out there, you simply dont know if you are buying genuine products,

the other great thing is the fpd and regulator will simply bolt onto the rails, making it a nice simple package.

​​​​@Krem Thanks for posting!
I'm looking for exactly this. Can you tell me what you needed to put in your cart to make a full primary/secondary rail set (with FPD, FPR, and FP Gauge)? What did you do for the connection to the OEM hardline? Did you need additional lines or fittings? I am a bit confused as to what I need to add to cart.

I am guessing that besides Primary/secondary rails, plus those 3 add ons, I'd need to include at least 1 hose to connect the two rails, plus 2 fittings to connect the rails to the fuel feed and return hard lines? Is there anything else? any plugs or adapters for the OEM fuel temp sensor? Need any -8AN ORB bungs?

What about dummy injectors or plugs to fill in your two empty slots on the secondary rail? Does it come with these?

(and out of curiosity, what injectors are you using?)
Thanks!!

 

Can we get an answer for this? i too am planning to pick up the Radium gear and am wondering whats the best way to connect to stock fuel lines.
