?? NISMO - Nissan Motor Sport OEM supplier, so direct fit for R34GT-T.

I'm not trying to pedal anything, just saying that that bloke made a mistake when he said that R34 NISMO injectors were 440cc that's all.

I'm not trying jam them down anyones throat, just trying to help out with some options. :)

Fair call, I'm just trying to figure out if there is a larger equivalent that came factory fitted to another engine. I can't justify near on $1k for an extra 100cc's for my daily :)

Deutschworks?

Does anyone know how big 350Z injectors are? being a 3.5L engine I'm hopinh they're bigger than 370cc..

From memory they're about 300cc....not big at all, as some zed people are using the R34 Blue 370's as upgrades.

I've been more than happy with the deatschwerks injectors, I've got the obsolete 550's the newer 600's replaced them on their site last year, they're 100% drop-ins

I remember asking the question about the XR6T injectors a while back, never actually found out though :)

480cc'S can go more then 242 kws cant they

from memory i pulled 215 from stocko ones would 100cc really be only 30kws more

(oh mines currently at 244Kws (have run 248Kws) with nismos and I could have sworn they were not maxing out yet )

Well my stag is making nearly 240awkw on stockers, they were pretty much maxed at ~260awkw and there was still a few psi left in the turbo which is why I'm looking for something a little bit larger :)

ok, blitz made good ones but discontinued, so pretty much forget about those. One wrecker i think in SA has some second hand ones but for about $1200

Nismo are the ONLY drop in ones, 4 hole spray pattern, $1200-$1300 delivered, stupidly expensive and rare as hens teeth to find second hand, trust me, i was looking for a while until a set turned up on ebay. And what do you know, someone on SAU is selling a set :banana:

Sard aren't straight drop in like the Nismo's, and frankly, don't have that brilliant a rep compared to the Nismo's.

Other options then become...

GTR injectors (need fuel rail and possibly resistor packs)

HKS fuel rail which gives you more options

Hi flows - done here locally or done via deutchworks, some people love them, some people hate them. RC Engineering in the states could probably also rustle up some hi-flows.

Then, i was going to go with ANOTHER option until i found the Nismo's. A guy in Melbourne was advertising converting side feed to top feed, using these billet aluminium bungs or something. I asked if he could go the OTHER way, top feed to side feed. Because if us NEO'ers went to side feed we'd have a ZILLION options. He doesn't see why you couldn't go top to side, but i never followed through with it cos i found the Nismo's.

I know there's no OEM info, but that's pretty much what i found out with after market options for the NEO, and yes it's VERY limited if you don't want hi-flows or get fiddly with new fuel rails.

I reckon someone should give the top-side feed conversion a shot, cos surely then there would be a lot more options available.

I had actually toyed with the idea of putting the R33 inlet runners on the Neo head and just using R33 side feeds on the stock rail....but I never got around to confirming the stud patterns matched up, anyone care to check it out?

Yeah thats the one, i got them ones highflowed to 555cc.

You had 350Z injectors hiflowed?

Also, anyone know if a 26 fuel rail will bolt up to the intake manifold? or could be made to bolt up? a fuel rail is just a fuel rail afterall.. and being able to use GTR injectors means I could then also use hand-me-downs from my 30!

Hey ppl's I'm still working on this little project. just waiting on a bit of cashola to come through.

can any 1 confirm if Neo Rb25 heads have the same injector spacing and mounting positions as a non NEO RB25 head?

also do R33's run the same style stock FPR. as i want to retain the stock FPR?

regards

Chris

you are a dingis . have you not read anything about this sublect at all ?

You sir are a Dingis for using the word Dingis. LOL

I am very confused at why u think this is such a stupid non thought out project.

Was it the part where I'm going to use cheap common injectors or the part were i asked if Neo and non Neo's had the same spacing between injectors.

Whether they be top feed or side feed is irrelevant.

Please explain where I have gone very very wrong?

regards

Chris

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
