Injector differences -- > RE Cosmo
Okay, I know there have been several threads regarding injector differences, but nothing that I can find on the Cosmo motors...
Specifically I'm trying to figure out what the Cosmo injectors are interchangeable with... More specifically, if I can get some 850cc FD injectors (side feed) do you think those would fit for the cosmo primaries? (side feed also). I know I could go find others, but hey, it seems like FD injectors are easy to come by and relatively cheap -- and the 800ish range is about right for what I want for my primaries. Secondaries I should be able to find as well -- top feeds, I think I could buy pretty easily from the forum stores or injector.com. |
JC Cosmos and FD RX-7s use exactly the same injectors. Both use 550cc/min primaries and 850cc/min secondaries, but I don't know if the two sizes are interchangable. Since you already have both sizes, try fitting the secondaries into the primary location.
|
It's my understanding that Cosmos have 550s all around. Primaries are side feed, secondaries are top feed -- but I thought they were all 550s. Not that I took it for gospel, but there was a thread that indicated such awhile back and I thought the person posting was a reputable source.... I'll try to find that thread.

I have to speak to a mate who owns a 13B JC Cosmo tomorrow, so I'll get that confirmed for you. I know he's has them cleaned and tested recently.

NZ any news?
Anyone else have any info? |
Finally found the thread I got my info from... still not sure if the cosmo's primaries and FDs are the same even tho they're all side feed. I'll have to ask j9fd3s...

heres a good shot of the primaries
http://www.2751engineering.com/13BRE_rail.jpg the secondaries on that motor were replaced with 1600's and a k2rd rail, the stock rail is almost identical to an 89-91 t2 rail, and the stock ingectors are as well mike |
cool, so one could conclude that basically all of these injectors are interchangeable across REs, S5, and FD motors -- assuming like configs (side feed or top feed).
that's what I needed to know! thanks!! |
