Neo Injector Size

[pipster11]

just got my ecutalk and need confirmations that the injector size is 370cc

had a google and could only find sites trying to sell me new ones

thanks

[wolverine]

yep, RB25DET neo is 370cc

[pipster11]

mad, i get 0.9 LPH fuel consumption at idle

now will just have to have a look at my slugish o2 sensor - yay

[RubyRS4]

Having said that, anyone know of a good place to buy an O2 sensor for a Neo motor ... without paying Nissan prices?

Search is you friend roo..... Get yourself an EL (I think) falcon one, fit the nissan plug and done

I've heard that ... but is it 100%?

And can the falcon pins come out of the falcon plug and go into the (recycled) nissan plug? I know you can't solder them.

Its all in the DIY sticky under O2 sensor

[pipster11]

u can use the el one or the one for an n14 (i think, sr20)

or the one to suit a 33 is fine but has a different plug still

[chook]

don't assume it will be 370cc exactly, prob affected by fuel pressure, worn and gunked injectors etc. After calibrating my ecutalk, best done on long trips, my injector value was 340cc.

I paid 78$ for a bosch OZA395-E2 oxy sensor, to suit 33GTST, it fitted my 32. check if plug is same for the neo at a local bursons?

nah its not the same, you'd still have to rewire it. the RB25 neo plug is a different plug to R32 RB20, so if a R33 one suits a R32, than i'd say the R33 one wont suit the neo.

in reference to injectors, are stagea s2 injectors side feed?

if they are, will a r33 top feel aftermarket rail fit?

thanks

[QWK32]

S2 Neo injectors are top feed same as R34 injectors.

[eXquiSit]

interesting... i only asked because on nengun/rhd-japan/etc etc it says that both s1 and s2 are side feed

not doubting you but have you pulled it out and inspected it first hand because the sites have conflicting information

thanks!

=)

[QWK32]

Yep, I have had my injectors out, and replaced them with a set of aftermarket top feed R34 GTT injectors. And still using the stock fuel rail. You can tell that they are top feeds without removing them, with the neo engine cover off you can easily see the first few injectors if you want to see for yourself.

[eXquiSit]

awesome!!!

thanks for that mate!

=)

would aftermarket gtr injectors fit?

or even gtr injectors?

[chuckie]

Hi guy`s i have put photo`s of injector up in few spot`s as there has been few TOPIC`S on them, O RING SIZE ETC ,

Cheer`s Chuckie.

[QWK32]

No, even though they are top feeds they are a different body shape/style than the GTR ones. They look the same as ford XR6 Turbo injectors, I think some people even use XR6 ones as an upgrade. I don't know what CC they are though.

Have a seach of the forum, there is a R34 Injector thread somewhere with a bit of good info in it (same engine as S2). From memory there was even a S2 injector thread started in the stagea forum a little while ago.

If your looking at injectors online I'd look at R34 GTT ones as the listings will probably be more accurate by the sounds of it.

Vq's run the the same injectors, I fitted the XR6t Deka 610cc ones which are a bit longer but work great. Cost around $500.

that makes sense, the ones I'm running are Deastchwerks injectors, even though they list them as RB25 NEO injectors they look like 350z (vq?) injectors but use a 9mm spacer to lengthen them to suit the NEO fuel rail. I was looking at the Deka ones too but I would have had to change the electrical plug on the wiring loom to use them.
