Sourcing Injectors for the SOHC

[Edub1]

I've searched & found tons of info about injectors and I still can't find the answers to these questions.

I am looking for easy fit 460cc injectors for my SOHC.

Which injectors are the easiest to find and fit?

If I need to use resistors, what do I need and where can I find it?

[LEMHEAD16]

I used 88 RX7 injectors, wired resistors and had them cleaned and flow benched by witchhunterperformance.com all for around 175 bucks. Get the injectors from Ebay and an injectors box from a CRX (or other honda)

[Edub1]

You mean the 87 RX-7? I think the 88 are high impedance and I'm not sure if they fit.

You say any Honda will have the right resistor box? Do you simply splice in line?

[wild_maxx]

hey i have a set of fully clean, flow tested, ohm check, balanced rx-7 550cc injectors. They are high impedence so no resistors needed and they are a direct fit into the KAE fuel rail.

i had them on my kaE-t for 1200 miles and controlled them with a safc II. i'll give them to you for 175.00 shipped. i am open to offers cause i need to sell them.

[Edub1]

Thanks but I don't want to go too big on account of it might make my ECU advance the timing when used with the Emanage.

[LEMHEAD16]

Yes, I meant 87 Rx-7. It was early when I posted that

Here is the injector box you need to run low imp. injectors. (cheap) http://cgi.ebay.com/ebaymotors...ZWDVW There is a thread on the forum somewhere about how to install them. IT is really easy though if you can solder.

Imagine that it is in the sticky Fiz used a DSM box but they work the same zerothread?id=119383

[Edub1]

Sweet. But you got me thinking - perhaps I should pull the box and injectors from a junkyard DSM. That way the injectors will be a little younger.

What should I look for if I go that route?

[LEMHEAD16]

I don't think the age of the injectors really matter if you are going to have them cleaned and tested. They basically rebuild them and they are good as new. Look at the inje tor spread sheet in the Sticky to see what DSM's will work

[Edub1]

Do all the injectors in the sticky fit easily into our motors?

I assume top feed for SOHC and side feed for DOHC?

[LEMHEAD16]

I had to trimn a little bit of the RX-7 injectors but yes they can all be made to fit pretty easily

[Edub1]

I just searched a little and found that the DSM injectors require boaring of the fuel rails.

I think it's back to the RX-7s

The 88 are high impedance - anyone know if they fit the SOHC?

[Iamjohnhayes]

has anyone ever tried or looked into Accel Injectors on a Sohc. i would imagine that they are much like msd injectors which require drilling out the fuel rail.

[12valveturbo]

I have seen lots of problems with accel injectors I would stay away from them.Msd injectors drop right in no drilling anything.

[180sx]

I HAVE 86 RX 7 460CC INJECTORS. ANYONE WANTS EM PM ME 100$

[Edub1]

I have seen lots of problems with accel injectors I would stay away from them.Msd injectors drop right in no drilling anything.

Which MSD injectors?

[Iamjohnhayes]

yes i would also love to know about the msd injectors in the ka-e rail that drop right in. as for the '88 Rx7 Injectors (N/a b/c i know the turbo ones are different) are they straight drop in and go or do you have to do anything. my brother is rebuilding his rx into a high compression turbo 13b and he was going to chuck his injectors.

[12valveturbo]

I have msd#2064 they are the 72lb injectors and I didnt have to machine anything. I just put them right in. Ive had them for a couple years with no problems. Any number from msd that starts with 206* should fit a sohc rail with out problems.

[Iamjohnhayes]

are the high or low impedance? did you have to rewire?

[12valveturbo]

they are 2ohm I have a standalone so Im afraid Im not up on the whole resistor thing

[Iamjohnhayes]

its cool. so you say anything with a 206 ( looks like the beging to all their "universal" injectors) in the front with fit the sohc fuel rail. Summit racing sells msd injectors that start with a 206 and ar 12 ohm.

[12valveturbo]

395cc 12ohm#2068228cc 16ohm #2067198cc 16ohm #2066520cc 12ohm #2063218cc 12ohm #2060250cc 12ohm #2069998cc 2ohm #2065749cc 2ohm #2064354cc 2ohm #2062270cc 2ohm #2061

[Iamjohnhayes]

Thanks gor the good info dude.

someone should add this to the injector list that is stick up.

[12valveturbo]

no problem

[Superist1]

sorry to hi-jack but I just got some 03 wrx injectors and was woundering if moddification would be required? and if any one knows which of the two prongs in the plug is what on my SOHC harnesss.

[hek1620]

do u still have those? i'm putting my kae-t together and i might need those if mine are bad. also, what are the last four numbers on them?

hey i have a set of fully clean, flow tested, ohm check, balanced rx-7 550cc injectors. They are high impedence so no resistors needed and they are a direct fit into the KAE fuel rail.

i had them on my kaE-t for 1200 miles and controlled them with a safc II. i'll give them to you for 175.00 shipped. i am open to offers cause i need to sell them.

[emperor_lunchbox]

Does anyone know if the projectnissan.com fuel rail will require boreing when used with GSX DSM injectors?I just got a set, and it looks like there is alot of work that needs to be done to make these work. If I have to bore out an aftermarket fuel rail and get an aftermarket FPR and get a resistor box, I think I might just have to sell these.

[Edub1]

Just got a set of 87 RX-7 460s on ebay. $60 with plugs and $60 cleaned and flowed.

$120 I have fresh 460s with plugs.

[LEMHEAD16]

YEAH!!
