R34 Injectors

[allthewaytotheskyline]

im looking like crazy for injectors and still finding it mearly impossible to find a set for a decent price.

not looking for more then 480 or higher then 550cc.

any updates!

[Wacky Dee]

check on importmonster.. I recently found a set of nismo 480cc's for less than $400 delivered, posted a thred about it because I know how much sought after they are here and it was deleted.

[allthewaytotheskyline]

do you still the link for it...as im not literate with how to use that site.

thanks.

[Wacky Dee]

you need to sign up ..its basically a company that does bidding on japanese yahoo auctions on your behalf (as most japanese sellers wont ship outside japan) organizes your delivery etc but charge a fee of course.

That particular auction is over ..not sure if it sold or if it will be relisted. There's a set of new nismo 480cc's up there right now for $700 but with shipping and other fees it comes to $1k

i bought a set of injectors off a user from SAU (Andy) and they're delphi 440cc injectors, apparently plug in and play. anyone heard of these?

[SS8_Gohan]

some other guy i just noticed recently was running Bosch injectors, drop in BUT you just have to fiddle with some wires or something. Apparently very easy and you could practically class as plug and play.

username is Luke ENR34 or something like that

on friday i found a suppy of injectors but they require plug changes (like all sard) and a rail spacer. I will have final kit pricing on monday arvo as i have a kit for testing, once im happy with fitment and tuneability i will update this thread. i am anticipating a big saving.....

there's a big difference between the nismo and sard injectors but ... from what I've read anyway. Apparenty the nismo ones have more spray nozzles and a finer spray pattern which results in better combustion = more power and better fuel economy.

Does anyone know how the deatschwerks compare to the nismo injectors ? Apparently they use 'Denso' brand. 440cc are about $700 delivered

hey these are the injectors in which im looking into getting..although i'd be looking at getting the 600cc...would they be fine for 280 to 300rwkw? or are they too big and will make tuning and idle odd?

also has anybody experienced them..i know 1 member on here is using them and was very happy with them.

also URAS let us know how the sard thing goes??

[Wacky Dee]

apparently denso = sard ? I just did a quick search for Denso and some people referred to them as SARD. I think 480cc is more than enough for about 300kW so 600cc should be plenty. Remember you will need a PFC or some other ecu management to use bigger injectors.

[urtwhistle]

Hey URAS, let me know how you go with your kit. as i was originaly planning to do a GB once i had all the bugs ironed out (hence my PM the other day)

but if you end up selling them for a good price there will be no advantage to doing the work my self.

another thing i noticed is that the old EF falcon 4L are a cheap way to get EV1 injector plugs.

siemens deka injectors = EV6 injector with EV1 plug

neo RB25 injectors = EV6 injector with nippon denso plug

falcon 4l = ev6 with ev1 plug

falcon v8 = ev6 with ev6 plug

yes efcourse im going to be using all the proper upgrades to go with it.

so the 600cc wont be too much..as ive heard oversizing injectors isnt a good thing.

there is a 440cc size but im thinking its not enough...for 280-300rwkw.

any opinions??

[Wacky Dee]

I'm pretty sure 440cc would be good for only about 250-260rwkw. Are you gonna use forged internals ? I wouldn't go above 260kw on a stock engine either unless you have forged internals

Looking to do the same

what's the go with these injectors?

what do i have to buy?

the 680cc would be great

[SS8_Gohan]

looks like you need a fuel rail and a dropping resistor?? 480's are the same price as the Nismo by the looks of it...

ill be going for approx 280rwkw..from what ive read a good tune is whats needed and my engine should be fine.

the tuner im using has a r34gtt with rb25neo and has a gt3540 on it pushing 305rwkw wiht standard internal and has been like that for almost a year with not an issue and still top compression.

deatchwerks do a 600cc straight fitment and plug in made from denso brand parts.

spoke to the guy there and he assured me they will do just as good as standard if not better.

with aussie dollar the way it is, it will cost me no more then $850 delivered to your door...for 600cc's of standard fitment.

pretty good if you ask me...i will let you all know how it goes when i get them.

Denso make SARD injectors aswell as others. I'm running 550cc Densos in my RB30DET. Perfectly fine, cost me $960 with new plugs though

SARD = Denso.. see above

URAS, very keen to see what you come up with

[SS8_Gohan]

the german sounding ones are just high flows, most likely of stock 350z injectors.

high flowing can be done in oz for much cheaper, so no point getting from the states. Just high flow your factory ones.
