call me an idiot for not knowing this, but where are they?... manifold, throttlebody?



And are they in any way similar to primarys or no?

It's late and I have had some wine (disclaimer) but depending on what year and type of 2nd Gen you have (you did post here) There are 4 injectors 2 are what you run on most the time, the others are what you get when you open it up more. They are under the manifold runners on mine in the housings, (I believe) The NA cars have 550cc in both primary and secondary. (identical) I, just this week, acquired 720cc injectors off a turbo motor (Thanks Jeff Clark) and after getting them cleaned and flowed by DR injector, (Monster flow rates) will be replacing them into my Secondary system and recalibrating my RTEK Chip to feed them correctly. Hoping for 10-25 more HP as my motor is built to rev to 9K! https://www.nopistons.com/forums/pub...R#>/tongue.gif

Will look at my SVC Manual if noone else reminds us which one is the #2s. Plan to swap mine this weekend so I'll have the manual out, anyway. Don't do this stuff of the top of my head.

Flow matching is a good thing.

On an n/a, there are the 2 primaries (under the manifold), and 2 secondaries (on top of the manifold). I thought the n/a's were 440cc, all 4 identical.

the t2s are 550cc and depending on year of the na motors they are 360cc to 460cc or someshit. i know the gslse where higher flowing then the s4\





randy

all TII injectors. primary and secondary are 550cc.



na's are 460cc.



and gsl-se's are 680cc.



the only one im not sure of are the na 2ng gens. they might be 430, i get confused. but they never came 720 in any rx7 stock. 850cc were stock in a 3rd gen secondary. and primary 500cc.



oh...i think secondary injectors turn on at around 3800rpm too.

ok thats right , for some reason i thought the nas where less cc then that but i am mistaken. least i got the t2 part right

Is it a good idea to use the GSL-SE's injectors as an upgrade on a TII if you've beefed up the ignition on a stock motor/turbo?

yep, its 11% more fuel, so it'll support a nice power increase

s4 only though due to the impedenance of the injectors. unless a resistor is used.

So S5 no good?
