Just to clarify, the RB26 and RB25 fuel rails all bolt up to the GReddy RB25 intake manifold. The difference is the injectors / FPR. I need to clarify as im doing a 25/30 using a greddy manifold and just need to open up my options for fuel rail, injectors and fpr.

Many thanks.

You will need a set (of 6) alloy injector collars to fit top feed injectors to the Greddy/copy inlet manifold, check out the "for sale" section of this forum, there is a guy who sells them for a reasonable cost.

Modifying Rochester injector plugs is easy, just trim off a couple of tabs with a Stanley knife and the Nissan plugs fit straight on. I have a picture somewhere, if I can find it I will post it up. I have a set of 1000 cc Rochesters in the RB31DET, for $77 each I didn't mind spending a couple of minutes each trimming the plugs.

I am in the process of testing 13 different types of JECS injectors (dont ask me where i got them from) i work in the automotive industry. these are all side feed and are the right impeadence for r32 and r33 gtst ecu's

RB20's come with top feed injectors standard.

Cheers

I know SK, :banana: they come with red top 270cc top feed. but if you are building a 30det based on a 33 head and you want a remapable ecu you end up with a bit of a bastardized combination like I have

r32, rb25 na vct head, rb30 block, rb20 loom, sensors, ecu, side feed rb25 injectors :)

Any chance you've got a part number or a picture of the Rochester injectors? or is there only one type of 1000cc Rochester injector?

so on that website that would be the 96lb injectors. never thought about getting these. much cheaper than anything else i'v seen.

96 lbs per hour = 1000 cc per minute (close enough anyway)

Cheers

My 1000cc Rochester injectors arrived yesterday and I've sent them off to be flow tested (just a little concerned about the lack of packaging, each injector was in a small ziplock bag with all 6 just throw loose into a postbag).

tuffcarparts is where I got them from, probably are alright but getting them flowtested anyway so I can hand my tuner known numbers and also so I can stagger them so highest flowing is at the back as I'm going to forward facing plenum.

Any 14mm fuel rail should be fine yeah? found an RB20 14mm rail on tweakit that I think is going to be the go.

The rail is like AU$240 I think, twin entry to suit 14mm o-rings and RB20 manifold.

I have a custom plenum with RB20 runners and seeing as no-one answered my question about RB26 rails onto RB20 runners, I kept looking for an RB20 specific item.

I figured I would just post in an existing topic instead of creating a new one.

What are peoples opinions on hiflowed stock injectors? Are they safe & reliable and comparable to Sards for example?

Seems nice to be able to save a few hundred bucks on a direct-fitment item too.

Personally i wouldnt go with highflow stock injectors. Prefer to get something that you know wont cause you any problems.

Ive considered this and with many people opinions bought Nismo 740cc injectors instead. Least i know they wont f**k up on me.

If it isn't to much trouble could you please post up a pic of the trimming of the plug.

Thanks

Sweet, one more quick question - does anyone know exactly which Subaru injectors can drop right in?

Is it just the V5 440cc Yellow ones? Heard you can just put em in and turn the plug around the other way and they are sweet?

      Compatible rear drive shafts R34 N/A?

      By RB25inside · Posted

      Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.

      Compatible rear drive shafts R34 N/A?

      By GTSBoy · Posted

      They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.

      GReddy Injector Help!

      By ChoppedSpots · Posted

      Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....

      GReddy Injector Help!

      By Dose Pipe Sutututu · Posted

      Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)

      GReddy Injector Help!

      By ChoppedSpots · Posted

      Thanks for the replies guys, it's really appreciated.  It seems the kit was supposed to come with those injector bosses but hasn't. Unsure if they'll help as even with the adaptors to make them a 3/4 height injector they still sit too far out so mount the fuel rail?
