R34 Injectors

[urtwhistle]

hello Just a quick question,

does any 1 know if the R34 neo injectors use an EV1 or EV6 style connector?

lastly can any 1 confirm if a a stock injector has these dimensions

inlet (top) to suit 13.5MM fuel rail (when o ring is compresed)

bottom to suit 14MM intake ( outside OD of Oring =15mm when not installed or compressed)

total length of injector 74.8MM

i am planning to use a siemens deka 610cc injector if all works, as there cheap and commonly used in XR6 turbo's (BF's)

Regards

Chris

ive been thinking of having a play with these as both are hi impedance, the plugs are differrent and im pretty sure the tops are larger on the XR6 injectors... so not drop in though.

[bubba]

What drop in replacement injectors are there for the Neo engines? Will GTR injectors fit?

Injectors in my stag are pretty close to maxing at 320awhp and a mate has some 550cc gtr style injectors I could get for cheap cheap..

[QWK32]

gtr injectors wont fit. different style/shaped injector.

[allthewaytotheskyline]

also curious to know which injectors will drop in fit in 34gtt.

hey the plugs dont really matter too much from what i have noticed as u can buy pigtails to convert or replace completely. yeah these injectors are a 14mm inlet. no idea what the stock inlet is or the total length.

ps i don't wanna pull all the gas injection crap off to get to the petrol 1's untill i really need to.

i mean u can pick up a set of seimens injectors for $450. i read some were that a spacer is all that is needed to fit them, but this doesn't sound correct to me.

Genuine Siemens / Mototron DEKA IV High Impedance Injectors

These injectors flow 60 lbs/hr at 43.5 PSI ( 3 BAR ) and up to 85 lbs/hr at 87 PSI! In addition, these units are high-impedance. Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed driveability. Adding to the flexibility of application, these units are high-impedance; making them compatible with most ECUs, while delivering the most flow available in a High-Impedance injector.

These injectors are able to function at high fuel pressures and don't exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures.

Engine performance and running quality are enhanced through the optimized spray pattern. Unlike competitors "pencil stream" high flow injectors; these High Flow injectors utilize a multi-orifice tip providing a true 30 degree spray pattern for improved mixture preparation. This results in lower BSFC and better idle quality than many injectors with less flow.

sard have a decent range of injectors that bolt in as do nismo but only 440, anything that will fit 350Z is a bolt in fitment.

[urtwhistle]

but there $1200, id rather spend 500 personaly

[cankas]

gees shop around you can find them for 300 cheaper than that, and with all the headaches you will have getting them working the extra 400 has paid for itself

[bubba]

I bought new big injectors for my RB30, don't want to do that again for the Stag so that's why I would like to find a DROP IN REPLACEMENT from an OEM application.

[Sheng]

also curious to know which injectors will drop in fit in 34gtt.

Go on any trader websites, they usually tell you, or just ask them.

urtwhistle- my injectors are highflowed to 555cc, there a company in oz that does it, think its German, forgot the name of the joint though

[bubba]

Deutschworks?

Does anyone know how big 350Z injectors are? being a 3.5L engine I'm hopinh they're bigger than 370cc..

Nismo do a drop in replacement for the GT-T. These are 440cc's, running them in my 34 at the moment, got them 2nd hand as well so a couple of hundred off retail. Pays to shop around on the forums

I think i'm just going to have to mill some hollow or hex bar to suit the 14mm injectors.

that is once i get a spare plenum and fuel rail and dead injector to mock up and jig. any 1 want to donate 1?

regards

Chris

I'm trying to figure out if there is an OEM alternative, i.e. like S15 injectors for normal RB25 or RX7 injectors etc etc

I have already spent nearly $1k on injectors for my RB30 and don't want to do that again when I only want to squeeze another ~80hp out of the Neo engine!

[Wogboy]

R34 GTT NISMO injectors are 480cc

[bubba]

Again, they are not OEM injectors. Stop trying to pedal your $850 injectors where we are trying to find OEM alternatives

?? NISMO - Nissan Motor Sport OEM supplier, so direct fit for R34GT-T.

I'm not trying to pedal anything, just saying that that bloke made a mistake when he said that R34 NISMO injectors were 440cc that's all.

I'm not trying jam them down anyones throat, just trying to help out with some options.

[urtwhistle]

i understand what both of you are saying. what i'm trying here is to work a nice cheap simple upgrade. due to R34 injectors being top feed and also the long pencil style it makes upgrades that touch more limited and expensive. If these seimens injectors work with out much trouble it will also mean that FORD MOTOR SPORTS injectors (come in the typhoons), BOSCH 968's (cheap common upgrades for XR6T's) and generally alot of other cheap oem common parts can be thrown in.

some times we need to think out of the box or we forever will just be screwed over with limited choices
