Dose Pipe Sutututu

Okay so besides the fact I can't seem to get ever so popular 1/2 height with extension injectors on, I decided to bend some left over strips of aluminium to fit my obsessively large 25 row Setrab oil cooler than cost as much as my kidney. Will redo the brackets again once I'm happy with fitment. (Yes that's a bit of cable ties on the rear end lol)

maybe convert to carbies, easier

Unfortunately you can't get high capacity unmodified injectors in 3/4 height. If you look closely at those tips of the Xspurt 3/4 height they have been milled off. I've spent decent coin on these unmodified Bosch 1550cc injectors and I do want to run them. I'm still super curious how people with ID1050/1300/1700X injectors are getting them to fit on NEO motors and also how people with the Bosch 2000/2200 CNG injectors got them to fit. There seems to be zero guides or images for these setups. My very last options are to either go back to a R33 intake manifold (gay) or buy a Hypertune (over priced) or equivalent plenum such as Otaku Garage/Madcat (China dim sim sui mai spec).

These are my photos, which shows an identical injector setup as per Injector Online. So you can see that the connector hits the intake manifold, and yes it's possible to turn some of them to allow the injector to be seated in however that means some injectors won't be perpendicular to the manifold (big no no). To make things more fun you also won't be able to get the connectors on lol. The best and probably only option I have is some form of 14mm to 14mm (male to female) injector seat as such. I've simulated this using the 1/2 to full length extension (hole is too small I know haha)

Some digging around it seems guys with BRZ/86 FA20DI N/A motors actually have the same issue but ID have come up with a solution for them. I am pretty sure it won't fit inside the RB25 NEO intake manifold

Funny you said that, I was tempted to grind a bit off the injector connectors so they can clear the top area of the intake manifold. I more curious to hear/see how guys with NEO motors fit those old 2000/2200 gaysex injectors back in the days as they're all 1/2 height also and 100% would have the same issues.

Long story short, I know RB25DET NEO plenums like to take 3/4 height top feed injectors, which are approximately 52~55cm o-ring to o-ring in distance. Most will just get a set of 1000cc Bosch injectors OR modified Bosch 1250cc injectors that are of that length. I wanted more fuel supply, so opted for the non-modified Bosch 1550cc (1650cc often advertised) injectors. These injectors are 1/2 height, and are approximately 40mm o-ring to o-ring in distance, with the correct extension you can make these the same height as your typical 3/4 height Bosch 1000cc or XSpurt 1000cc injector. Below is the same injector now with the extension, giving you that 3/4 height. Theoretically they now should just bolt up and off you go right? Many sites from various countries tend to advertise 1/2 height injectors with extensions (making them 3/4 height injectors) as direct fit - however here's the fun part, you actually can't even get the injector to go all the way into the injector seat on the RB25DET NEO intake manifold. They simply just don't work! Problem is, as they are so short before the hard plastic that keeps the o-ring captive doesn't even touch the injector seating area of the intake manifold because the injector plug ends up touching the intake manifold. Being the person that at times thinks outside the box, I went on and installed a bunch of 14mmx5.5mm injector buffers from a GT-R thinking that would solve the problem. Well - it kind of did, now there's a bit of space and the injectors are somewhat sealing well... but yes, now the connectors won't even go on! because there's simply not enough room. So I am really intrigued how these different suppliers are all listing these injectors as direct fit - when clearly they won't? (noting all the injectors are 1/2 height with either full height or 3/4 height extensions) https://www.injectorsonline.com/au/1500cc-xspurt-injectors-x-6-neo.html https://www.golebysparts.com.au/parts/view/2053/58/nissan-rb20-25-26/fuel-rails-and-fuel-rail-injector-kits/rb25-r34-neo-plazmaman-fuel-rail-kit-2000cc-injectors https://www.ebay.com.au/itm/Nissan-1300cc-Fuel-injectors-RB25DET-NEO-R34-Skyline-Stagea-C34-Plug-Play/182639648111?epid=6004139375&hash=item2a862bdd6f:g:S~QAAOSw4DJYlreh https://www.ebay.com.au/itm/Bosch-2200cc-Flow-Matched-Injector-Set-For-Nissan-Skyline-R33-I6-RB25-Neo/222702641007?hash=item33da1c9f6f:g:u9wAAOSw0exZ-oq3 So the question, how did you guys with 2000/2200cc Bosch CNG or ID1050/1300/1700 injectors get them on? considering they are all 1/2 height and all require to be extended? I would assume all the plugs would hit the same region and would disrupt how the injector would be seated. And FWIW, I'm using a Plazmaman rail (still, doesn't affect how the connects sit and/or hit the intake). (yes I even changed extenders so they're identical to the Xspurt kit, I sourced my injectors elsewhere though) Also you can't really rotate the plugs upwards because the injectors no longer will seal properly. My ultimate last option is to go install a R33 intake manifold on my R34 NEO motor (which I don't want to do). Thanks all!

Sequential shift, but you still need to use the clutch and make sure you lift off the accelerator... quite pointless and being Nissan, the FS5W30A gearset, they don't like to be shifted fast and at super high RPM.

Turn down the boost, stop trying to cut sick.

Nah, look at @klutched's build has stock plenum and high mount.

Just need the injectors to fit somehow, plenum on, redo the entire oil system (as the old one was filled with bits of metal) and then slot the lot in. Honestly over it

If my stupid build ever finishes or if I don't rage quit and burn the lot I'm going to try beat that mph

adjust the rod of your clutch pedal and/or maybe the bolt that controls the height limit of the clutch pedal.

and they're shit.. that sequential shifter is also shit.. you forget to clutch and boom! A proper sequential box, with strain gauge to cut ignition/rpm and/or shut your TB via DBW is the only way. You can't just throw loads of RPM and torque in between gears, even DSG cuts torque via a torque management strategy - thus the farts and pops.

did you bench bleed it?

nice nice!!! getting faster

if you ever want to make 500kW I have a brand new motor that's never started before sitting at home... Kind of over it.. so if you come give me enough cash you can take the lot and if you give me enough I'll throw in a free car with enough track suspension mods you'll cum your pants.. all it needs is a roll cage and will be competitive.. has Brembo brakes too.

Get a RB25DET NEO head on it, bring up the comp to about 11:1, put massive cams into it and rev it to the moon... could even adapt ITBs to it. A high comp, 3.0L, NA with ITBs and VCT would be pretty fun. And as Bill said, nitrous.. I would spray nitrous into it.

Just took a stab and ordered the lower injector insulators/seals from a RB26. Let's see how that goes lol

No to Hybrid manifolds, great way to destroy a $3000 ish turbo

1250cc would be plenty,, also they're easier to fit as they're 3/4 length not 1/2 length like the 1300/1550/1700 injectors out there.

buy my shit, offer me a reasonable price, and perhaps we can transact on a reasonable deal

yummy... VWs suck, DSG boxes fall out and cam chains/tensioners fail, not to mention the odd cam shaft snapping!!!!

Thread bump!! So I'm having massive issue trying to fit Bosch 1550cc injectors to a RB25 NEO plenum, which are 1/2 height injectors. I have the extenders to make them 3/4 height in order to fit my Plazmaman rail. 1st issue, injector doesn't seem to go all the way in 2nd issue, connector hits the plenum so there's no way of plugging them in. What I suspect may work is for me to install the RB26 injector "square" or insulator to bring the injectors up about 5mm. How have others overcome this? Besides the obvious and getting 3/4 height injectors. I'm sure in the past many have run 2000/2200cc CNG injectors on their NEO motors which also only come in 1/2 height. Sigh...

2000cc or 2200cc injectors are junk, avoid! They're cheap for a reason because suppliers are overstocked on useless CNG injectors.
