Does anybody know where I could buy some fuel injectors for cheaper then what they sell it on rx7.com for? http://www.rx7.com/cgi-local/2catalog.cgi?cat=12&part=6

I've gotten my exhaust from RB and had ported the wastegate, now I am putting everything back. Along the way I ran into some problems, like noticing a leak from a crack in my intake manifold gaske. So thats been replaced now and the turbo/manifold are back on. Putting the fuel injectors in and ouch! my secondary injector broke <---- the plastic peace thats on top. So what to do? I call AutoZone 150 each and special order, check mazdatrix.com 294!!!!!!! rx7.com 550cc $$$122 nice but still lots more che ching then I wanna spend.

tell me if this is feasable
Option #1: Put the old one in to atleast see if my turbo even boosts anymore/ car works properly (up to 4k rpm)

Option #2: Buy only one fuel injector instead of 4
Option #3: buy all 4 122*4 ??? hmmm so thats 488 and at a constant rate of $10/h at my job I'll have that paid off in the course of 48.8 working hours.

 

*edit* or option 666: Get a whole new fuel management system

 

well I found some on the net for 76.95 at http://www.fuel-injection-parts.com/...987-parts.html

Does anybody know if it makes a difference between first half vs second half 1987 tII? mazda trixs had this to say
"Note: For higher fuel flow in an 86-87 1/2 Turbo or Non-Turbo, the 84-85 injectors may be substituted in either the primary or secondary position (Not recommended in primary). The cutoff for 87 1/2 is June 1987 and splits at VIN #7601. The SE injectors will NOT work in engines after this VIN numbers"

So how do I know which fuel injectors is the web site posted above is selling, or does it even matter for me?

P.S. These must be some dumbass questions because no one seems to wanna anwser them.

 

1. I am pretty sure thats going to be N/a injectors.
2. It should be self apparant that you have to check your VIN to see which impedance you need.
3. Victoria British has injectors for like 90 dollars.

 

Thanks, my question about the VIN was about the confusion on the "The Se injectors will NOT work in engines after this VIN" so I was wondering if these (the website stated) would be the se injectors, thats all.

P.S. can you only look at the catalog through the magazine?

 

The SE injectors will only work on the early series four. Those early series four had low impedence injectors..just like the SE (SE as in 1986SE RX-7).

It's like this. Early series four and SE injectors ohm out at 2 to 3 ohms. The later series four and series five use injectors that ohm out at somewhere around 12ohms.

Go to CARPARTS.COM if you want cheap inectors, or Steve's Foreign Car Parts down on W.Vickery in Ft Worth. Somehow I don't think they have a website.

Actually I don't quite understand your question. You know that SE are the first generation cars that had fuel injection? Like a 1986SE RX7. And they are 680cc injectors. Good for the secondaries only (on the whole a true statement).

Or is it 1986RX7SE?????

 

Go to injector.com (or fuelinjector.com...forget what it is). Find a car that has the size and shape you want, then go to the wreckers and buy them. BTW, full size Fords (LTD, Crown Vic) use 1600CC injectors in the V8...

 

I scanned this thread a few times now, and I still can't determine if your looking for N/A injectors or TII injectors. It would have been real easy if in the first post you spelled it out... (BTW, my bad if it is appearent and I missed it!!!)

Having said all of that, I found some on ebay...4 for cheap

He has a turbo, needs 550cc (or better on secondaries)

Try http://www.atlantarx7.com/fuel2gen.html

I luv ebay.......Mazda RX7 RX-7 S5 520cc fuel injectors use the wrong connector for 88 and earlier (can modify harness for a full set, but NOT for 1 injector), are high impedence, and never existed at 520cc, only 460cc(NA) and 550cc(turbo).

 

Yea sorry, its a 1987 turbo II and it was built in 03/87 and my fuel injectors are before the cut off "before June 6th), I'm sorta confused now, what size are my injectors are they 520cc's? or 550cc's? Plus can I use the NA injectors on my TII?

Thanks for all of the links asherwood, thats nice searching, cuz I searched ebay and found nada, what key words are u using?

P.S. thanks again so it looks like from asherwoods list I might not be able to use any of them, except still pending on the na question. And I know I cannot use the S5 (1989 and up) injectors.

could i use 850cc fd secondaries...?

 

i should add, that's for an s5 tII

 

Yeah, but I think you would need some type of fuel manegment computer, like an S-AFCII, so you wouldn't be running really rich. Im not 100% sure on this, so correct me if I'm wrong.

 

yeah, but of course...

i was just wondering if it was the right impedance and stuffs...

 

anyone know? 850 cc fd secondaries... are they the right impedance to be used on an s5 tII?
