No bigger injectors then 780cc's...?
Ok, i called my local ( only ) rotary shop here in calgary and they are telling me that there are no injectors for my car past 720cc's, ( 780cc custom made ), i called complete BS when i heard this, i want/need 860cc's and they are telling me there are none for my car, wtf...?
i have an 1989 S5 turbo, S4 T2 block with all S5 externals....
anyone know where i can get the injectors i need?...
thanx....
P.S. need a direct bolt-in style....

these fit into my secondary position fine. Hondahater...or Iliketoeatricers gave me the idea. Not sure which of the two =/ They told me that the grommet would be squished a bit...but it works fine. I have mine in and they fit the secondary rail. (I bought 2) Haven't tried primary.

I think they're telling you there are no stock replacement high imp injectors that large. The ones most people use are low-imp square connectors (you have oval). What you do is hack off your connectors, solder on the square ones, then solder in resistors at the ECU, and you can use larger (890, 1600, whatever)

If you know they exist why dont you just search or look at other people's setups?
If you want to get technical if you have an s5 harness with the oval injector connector plugs nothing will be direct bolt in because most high CC injectors are low impedence (require soldering resistors) and also most are bosch style plug (square connector) so you will need to solder those also.
Basically any top feed injector that can fit a DSM or honda will work, some may require slight modification to fit into the rails. Search for 1600cc injector modification and I'm sure you'll find some write ups. Personally I used 1000cc PTE injectors and they went in no problem.
EDIT: looks like all 3 of us posted at once

i got these, my friend had them when he owned my RX7 and he said they were 720cc's....
but these are the wrong imped for my car, i know the resistor thing, but do these look like they would work?...
they are DENSO by the way....
and incase someone didnt read or skipped over, i have an S4 T2 block with S5 T2 externals....
( Had to take the pic in the bathroom, enough light for my shitty cam.... )

I didnt really want to start a new thread so ill jsut ask it here.. what kind of benifits do you gain from bigger injectors? say I was to go with 720cc injectors with the stock ecu and stuff. would it do anything but hurt my gas mileage?

im guessing youre refering to the low imp. 720's which they all are. youd need to solder in resistors next to the ecu and solder in dif. plug connectors from what im gathering. dont quote me on this cause im about as far on this as you are.
if ya want to part with those 720's gimme a pm^^^^^

i really dont think its that hard. go to radio shack ask for resistors, 10ohm/10watt purchase of 2 part# 271-132. these wire into the ecu for the injectors and then you do the same for youre connectors. it might take a little time but i think its possible. you might not even need the connectors but someone on hear that knows will tell ya.

wow, with those part numbers i can get them cheap!...
RX7 specialties was about to charge me $14 EACH.... and thats not to install them eithe!... ( $30 )....

BTW, you do have something to control those larger injectors, right? Just putting them in place of your secondaries is going to make the car run super rich whenever the secondaries kick in.

i have a PFC Fcon right now and an SAFC-II ready to be installed....
i'm a little afraid of installing the SAFC-II though, i dont want to install it and all the sudden run lean with the 720's or something freaky like that....
i was thinking i should install it, let the car sit for a week or so till i can get on the dyno....
unless ofcourse the great Aaron can share his wisdom using the SAFC!...
:P

i'll get it installed and tuned within' dayz i guess, will be the best bet....

A non-tuned S-AFC is exactly like having none installed. If all the corrections are set to zero, then the fuel map is unchanged.
Remember, if you get an S-AFC, you need to have it tuned. This involves a bit of investment, since it likely will take an hour or so on the dyno and a wideband.
