Neo Injector Size

QWK32: interesting... going off nengun again... they reckon (for hks injectors anyways) that r34 gtt is same part number as r32/33/34 gtr

chuckie:im looking thru your posts now

thanks!

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.

Plug is the easy part, they are around 10mm longer and hit the plenum on the vq so I had to fit a plenum spacer. Should be easier on the rb's

i dont understand how they can have them listed all as the same thing. especially since GTR injectors are low impedance and RB25 Neo's are high impedance. heres a pic i dug up of the different shapes of RB injectors, they are nismo ones but show the shapes/types the same as the stock ones are. S2 NEO stagea's are the same as R34 NEO, purple ones down the bottom. stock S2 ones look exactly the same only blue. S1 is the same as R33.

Plug is the easy part, they are around 10mm longer and hit the plenum on the vq so I had to fit a plenum spacer. Should be easier on the rb's

yeah apart from needing to change plugs they would be a direct fit. at the time the us dollar was crap so i could get the deatschwerks which are a direct fit no mod injector for the same as the Deka kits were going for.

yea thanks for that... it seems nengun is tellin porkies pies...

neo injectors seems hard to come by... i was wondering if you used a r33 aftermarekt fuel rail would it be possible to use gtr injectors as they are easier to come by?

anyone know?

thanks!

I have done a fair bit of research in the few weeks on these as I need some 650cc or so

The seimens deka 3/4 length only comes in upto 550cc

The full length ones go over 1000cc

Either can be used, just need to space the fuel rail to suit, plus the plugs are different

Approx $70-75 each plus plugs

full length are used in BA-BF XR6 turbo and I think LS1

3/4 length are from FG XR6 turbo and holden lS2 and LS3

The more expensive options

Biggest nismo are 480cc, I just sold mine to bigger

Blitz used to sell 525cc, I use to use these as well

I think Sard make some

Nismo 480cc top feeds for a neo engine are available at Nengun.

ok so do the 'cheap' injectors offer good quality spray pattern or is it better to go the expensive route n get say sards if you need bigger?

how much power does each cc injector support?

i know there is a bit of difference between setups but what is the norm for say nismo 480cc, etc etc

thanks!

Nismo spray pattern is reputedly one of the best and should be good for 480hp.

nice!!

now for my previous question...what other top feed high imp is readily available from the big names?

i ask because if you can get a top feed rail for r33 it should bolt up and thus you can run a bigger range (hopefully) of top feeds

My deka's are 610's and 4 hole spray pattern, same as Nismo. I have no issues at all running E85 through them constantly. Around 250kw with plenty of headroom. Theres no way I was going to spend $1500 on injectors.
