Yep, one of the sets you sold to my mate in Newcastle had a lot of problems with fitment, was quite the muck around. This was the stainless 1400cc E85 injectors btw.

(This should not be read as blaming Scotty in any way, we had heard that it would be difficult to fit them and they would just fit under there. Turns out just fits is an understatement on an R33 RB25 plenum)

That was me, it was quite a hassle in fitting them and mucking around but worked out in the end.

Ok.

The spacers where to long had to be machined down.

Had to take out the idle control had to be taken out because it was hitting the rail.

The o-rings in the bossers had to be changed to smaller so the bossers could fit in the inlet manifold.

The o-rings on the end of the injecters that go in to the bossers had to be changed so they would not leak as well.

Thats what feedback I got from the guy who I got to install them, just some feed back

Well the car is still a street car so I was trying to keep the "factory" looking engine bay, but guess i have gone well past that now haha, doesn't help when I have the external wastegate on the rear housing sticking straight up haha.

But yea, FFP is on the cards eventually

If it were possible to have a banjo fitting with a 90 degree tube facing back along the top of the rail it would look standardish to uneducated eyes . Trouble is most rails have those O Ring Boss female sockets and I'm not sure if there is suitable banjo fittings for them . I looked at Weber carburettor ones but the sticking point is their 14mm threads .

The drama is that the aftermarket wants to sell gear that looks like race stuff - all pretty anodised for those who want to stand out . Stealth takes a bit more effort to find ways that look like OE . I'm really surprised rails aren't made to suit commonly available plain looking banjo fittings because slipping on and clamping fuel hoses could be so easy .

Um......the reg doesn't have to be bolted to the rail. Just screw a fitting into the rail, drop a length of hose down under the manifold where the reg can be attached somewhere. Job done. Paint the rail with a paint that looks like cad plating. Even a light dusting of cold-gal would do to make it look scruffy and unloved. Instant camo.

My train of thought was to have the fuel supply and return as a manufacturer would and enough have banjo fittings if they enter and exit the ends of the rail .

The way I see it the head of a Banjo bolt is a lot tougher than an aluminium barb or bend and better supported . If the Banjos outlet went back over the nose of the rail it would be simple to connect it up with the standard hard lines and park a reg where the damper is on a standard R33 . Same at the back with a hose over the rail leading back into the standard return line . Some RB25s had a steel line clamped to the std rail rather than the fixed one brazed in at the back like my S2 one has .

You can't get more factory appearing than standard parts so the more you use the less molested it looks .

got my injector kit.. will measure up & take photos once fitted..

Hopefully won't have any issues with fitting, the rail looks a little slimmer than other ones which probably aids in fitment.

Which one did you get again? I got my kit from Kudos Motorsport today, it all looks so pretty :) haha

The rail looks pretty cool, although not sure how it would go under a stock manifold. Seen as that isn't a concern for me, I'm not real worried

I'm just wondering now if I'll keep the fuel damper or not. I like keeping everything that came on the car (where it doesnt need upgrading/touching) so I'll probably end up keeping it

Fair enough :)

I'm going to make a new injector harness up with the NIssan plug (8 pin?) at one end and the USCAR plugs at the other end so I can run it nice and neat and be happy that its all new. Have a mate that gets all the Nissan plugs for his stock so shouldnt be to hard once I get some USCAR ones. harness could probably use with a freshen up seen as I've already pulled it apart and re-taped it up once before.

Update:

Injector kit bolted straight up, no mucking about, no grinding OR relocating any hoses as such. After bolting up all the parts, went into WARI and adjusted my injector scaling & voltage offset table. Fired up the car, started first go on E85 (it never did before with the Five-O Side feeds).

I am very impressed, dicked around with the VE table and got them to idle at 15.7 AFR (gasoline scale). Car idled without any farts & pops, etc. I must say new age injectors are just wonderful.. with low pulse widths and great spray pattern - it makes a world of a difference. To be honest, I don't think I've heard my car idle that nice - even when stock!

I didn't get much of a chance to do any tuning as I threw out my back at the gym.. been in loads of pain, however will be doing some touch ups tonight after work..

I CAN'T WAIT :D

What CC are the DEKAs you got and are they the 1/2 length ones?

875cc / 80lb DEKA IV and yes, 1/2 length - 38mm from O-ring to O-ring..

Yesterday arvo when I started the car, I nearly cried :wub: - it was beautiful... cold start on E85 without any gay pops, farts and stalling.

Good work for taking the plunge will keep this option in mind if my fiveo's ever deceide to die. how much did it all cost u?

Under 800$ including fittings, hoses, etc.

However if something goes wrong I will cry, zero local warranty support, zero go to person.

I'm just too poor to buy IDs or Xspurt lol

So do Xspurt. There are many sizes available in the half height, that isn't the issue. The problem is no-one has a drop in top feed solution for the 33 gtst, you need to muck around with fittings, spacers etc. If I can work it out I will be able to offer a guaranteed to fit solution for those who aren't willing or unable to modify parts to fit.

If you get shorty injectors and any generic RB rail kit the only thing that needs to be modified is the spacers and shorter bolts need to be used than the ones provided with the rail kit.....I think I used 2 of the standard spacers and the standard bolts from memory....its not rocket science....

What are your opinions on the ID/Xspurt 2000's, will they idle and behave as good as the 1000's? cause they would make fitment a lot easier and neater.

Edited by AngryRB

The 1000's come in short lengths too Mark, how would they help with fitment?

Unfortunately the 2000's have some issues, especially on ethanol. They are not designed for liquid fuels as they are natural gas injectors. They idle fine, although I try to recommend the 1400cc stainless Xspurts these days for fuel compatibility.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.
