rx8 injectors yellows for FD primary
 

y? they are same technology as ID injectors much more control over stock units for the fraction of the price and i got bunch of them...

yellows uncapped should flow around 720-750cc

and read ones would flow 600-620cc uncapped ...or so i heard

perfect for primary

it fits in there good....just mater of developing primary rail to work with it...witch shouldn't be to hard

did any one do this all ready on there FD...i know miata guys and some fc use them

give it a shot, it will probably work out pretty well if you can get the fitment taken care of.

i sent email to kgparts to see how much would cost me to make the rail

didn't get any response from kgparts

talked to a local cnc shop they are interested

just wondering if there is any interest in the community to have this developed

probably would need some kinda minimum order of 5 or so

looks like their standard rail should work, all you need is shorter standoff legs.

i'm sure i could throw together a primary rail but i'm too busy taking care of other things at the moment, as i would need to get a pair of the injectors and the rail materials before even getting started.

sounds like a good idea though and will have to add it to my long list of "to do" things.

i think their rails are bored out for Bosch type injectors... so i was asking them if they could bore it out for rx8 injectors

either way i'd need to find a set and order the rail stock.

curious what you mean by uncapped? the yellows are only rated at 440cc, so we're doubling the output how?

here is some pic of the injectors i uncapped... rx8 dose not have return fuel system so by uncapping injectors and adding a 1:1 frp and raising fuel pressure to 43psi

VS stock

if you have means of producing this real i could send out the injectors your way and some fuel rail stock which is really cheap

Found this online. They claim around 640cc if I did my math correctly with their modification, at $25 with OEM trade that is a pretty good deal.

Someone on the Miata board flow tested a pair of stock and they came out at 450cc which is within the tolerances of them being 440cc stock, that was at 43psi, those were completely stock no modifications. at 450cc with the modification claims of 47% gains would put them at ~660cc. They are a high pressure injector with great atomization and might be a very good replacement for stock FD injectors, keep us updated on how this goes and hope Karack can come up with something for a great rail.

This is for the yellow ones.

sure i can make the rails and legs, just depends when i can squeeze it into my schedule.

shoot me a pm when you got some time

in the meantime i will be working on finding better rubber grommet then rx8 stock one

this type of rubber grommet might work better

Why not just buy the bosch EV14 750cc injector so it fits standard top-feed rail and avoid all the trouble?

dose anyone know if anyone makes 11mm to14mm injector adapter

i have been searching but all i found was 14mm to 11mm adapter

ok i found couple of interesting things

here is a drill bit for drilling fuel rails for 11mm injector BY RMR

they also have good price on fuel rail stock
http://www.rossmachineracing.com/dash6.html

was going to call them and see if they could have one made for me
but i jut might attempt this my self

Yes, its called a new O-ring and Grommet

Not sure why you are going crazy over making an 11mm rail or trying to find an adapter for 11 to 14mm when for under $2 your problem is solved...

yep all you have to do is switch the 11mm oring to a 14mm oring and your set.

you see that only you two came up with that solution...that wont work

Today I'm cranky and tired of useless comments like the one quoted.

1) OK, so it won't work. Please explain why not.

2) Explain what will work.

ok here is a pic so you guys can see y it wont work

stock rx8 fuel rail spacing for the injectors works when placed in to fd housing... just standoff leg is to long....so you cant bolt it down...but there wouldn't be any point in using stock rx8 rail any way

as you can see openings on top feed fuel rail for Bosch type injectors are much larger then denso
that's why i was looking in to spacers (top hat)
and that why you cant just shove in a larger o-ring in there

unless you wanna start a fire

whats the lenght of the injectors 48mm with a 11mm oring?

Cool, thanks for the explanation.
