Hey People,

Last week I destroyed my stock ER34 Ceramic Turbo and I'm in the process of buying some parts to get back on the road.

So far I have purchased:

- HKS GT-RS Turbo

- Apexi Power FC

- Z32 AFM

- Walbro Fuel Pump

Current Modifications Include:

- HKS Hi-Power Exhaust

- Tein Super Streets W/ EDFC

I am looking at getting a V-SPL front mound and Greddy Radiator and plan to run roughly 1bar boost.

All I have left to purchase is injectors but cant seem to find a good set around 500cc - 780cc which is what I believe I need for this setup. Can anyone recommend a good quality injector (good atomisation and wont cause rough idle) that will not bottleneck roughly 270rwkw?

I have read mixed reviews on the Nismo 480cc Injectors regarding the power that they can handle...

Any other thoughts or ideas on this setup would be greatly appreciated.

Cheers Craig.

I dont think the new radiator is needed unless there's something wrong with your current one, but I'm not an expert.

Can't remember if you mentioned one or not but a boost controller of some description might be an idea as well.

If your not keen on cutting a hole in your car for the return pipe on the fmic you listed, maybe look at a blitz return flow one, but that's up to you.

Agreed, the radiator isn't needed.

With the injectors, I take it you want something that is direct plug and play? Of the list that you put up, I believe only the Power Enterprise injectors will fit straight in. The Nismo 480's will as well, so depends on what your goals are for the car. I would recommend getting bigger injectors to accommodate any changes you want to make in the future.

Pretty sure the R33 and R32 aren't top feed but the R34 is. These injectors would be good.

What do you mean mixed reviews?

A 480cc injector, will support 480hp (360kw) on PULP - or there abouts for the sake of the conversation at hand (it's not 100% accurate, but near enough).

Also consider GTRs will make ~300rwkw on factory injectors. They use a 440cc injector.

Nismo 480cc will be more injector than you'll need for a GT-RS.

What i would be more concerned about is the Walbro fuel pump. This is the suspect part. Some seem to flow fine, others simply do not - that is the 'mixed review' part of your setup.

I also think you'll need more than 1bar for the power you are chasing.

Aren't the Nismo 480 one of the only bolt-in for a NEO?

From what I found when looking for my injectors, yes.

From memory my options were the Nismo 480's (wanted bigger), Siemens Deka's (tuner told me not to), Deatschwerks (couldn't find a lot of info), and the Power Enterprise which is what I ended up going with.

Get the ID1000s (Bosch) they work well at low duty cycles as well.

Forget the radiator

Does the HKS exhaust come with a front pipe? You will need a 3in front pipe.

Consider getting a Nistune board.

Well you said:

But they won't suit the stock setup.

What stock setup?

I'm confuse

Oh no no, that was your post getting in the way lol :P

I was referring to the ID1000's that Artz posted. They won't suit the stock setup. I took a bit long replying and didn't see your post so I didn't bother quoting haha.

They are topfeed. Do they not fit physically or electrically?

You can get the 14mm collar, so they fit physically. Need a spacer because they are full length while GTT injectors are 3/4 length. They use different plugs is the biggest issue, not a big deal if you know what you're doing or getting them installed. So it's not a huge lot of stuffing around to fit them.

Was just mentioning in case the OP is after drop in OEM replacements and doesn't want to modify anything.

You can just buy adaptor plugs, makes it easier as well for those worried about defects, as opposed to re-wiring the loom

Yeh? Wasn't aware... Do you know where from? I just ordered a set of ID1000's, would be good if I didn't have to rewire.

ill just chime in on the injector side..

cheapest and best injector is the Bosch ID1000's.. they come in either 14mm 3/4 length (standard GTT fuel rail) or 11mm 3/4or full length (GTR fuel rail). They have the best low pulse and spray pattern and cause no idle issues myself, n1GTR and piggaz on here are 3 cars that use these injectors with perfect idle (these are the only 3 that I have had first hand contact with) They also come with the assosiated plugs, pins, baskets which is a 20 min job to repin your existing injector loom (which is 2 clips and 1 plug to remove)

I ended up going with the XSPURTS 1000cc, they are a Bosch injector that is apparently modified, they were plug in units but they are full height which didn't matter to me as i ran a HKS rail anyway.... They weren't cheap though ($990 i think).... I originally had SARD 550's which were a drop in injector too, they just had a small rail spacer.

There are plenty of cheaper injectors out there, but i figured its one of those things i want to fit and forget so i spent the extra cash on them, they should suit any further upgrades too

      R32 GTST - 600KW+ RB28/CD009 Build

      By TurboTapin · Posted

      Car has been running great, I've put about 300km's of break in time on it. First thing that stands out with properly sealing rings is no more noticeable crankcase smell coming out of my catch can. This may seem insignificant, but the constant smell while driving around was infuriating. It's also nice to see my oil level remain stable. Two new issues have developed that I only noticed this weekend though. There's a very noticeable driveline vibration past 100kmh. I only noticed it now as I've been babying it under 100kmh in the backroads. This comes as no surprise as I'm running a one-piece shaft, and I paid zero attention to my driveshaft angle when I put everything back in. I also have a fair bit of voltage drop on hot starts. The starter audibly is forcing. No issues on cold start though. I must not have removed all the paint under my main block ground during assembly. I'll try and take care of both those issues this week once the kids are asleep.  I also received all the parts I was missing for my direct port setup. I will hopefully have pictures of that up soon. I'm hoping to get back on the dyno the week of June 30th as I'll be on vacation. I'm confident I should be able to make north of 500rwkw on pump gas and WMI. I'll go back again later this summer with E98, but I want to confirm my ethanol content sensor is working properly first. I've never seen it read anything but 11%. This makes sense for our 10% ethanol content pump gas here, but I would expect the occasional movement between fill ups.

      The Evolution Of "night Fury"

      By jez NF · Posted

      75% complete. Will now need to get a new axle with 5x114.3 hubs and then figure out how to customize some mudguards for it once the wheels are on.

      Trailer prep is underway... Lined up the wheel to get a rough indication of how it would sit Then removed all the bits (as far as possible) and gave the frame a light sand and quick lick of paint   Then added some carpet

      gauge needle removal

      By JC71 · Posted

      okay, so I figured this out, removed needles and reinstalled after swapping the gauge face on my triple gauge for my ER34, all work and look good. I tried to do the same for the main cluster, but the main cluster gauge faces are dished, the replacement gauge face are flat, so due to the dish in the org face ,mounting backing plate (clear) and depth of the needle, the flat gauge face will not work. I notice that R34 gtr gauges are flat, appears to be different clear backing plate that aren't dished. are these available, or what have others done to install flat gauge faces?

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Cheers mate. Seems some people get lucky others don't. It looks like the motor was detonating (to be expected if it was overboosting I suppose) as the pistons had a lot of detonation damage, and the bearings were stuffed. The bores were very scoured too, not sure if that's from the pistons or bits of ceramic turbo. By the by now. Have been trying to avoid the rabbit hole too much on the rebuild, and there's been a few hurdles along the way, but with any luck I'll have the car back soon™. Might even pop up a thread then.
