Also is this still correct? As i am going highmount i need to get a new oil feed line made.

so a -4 AN oil feed hose with no restrictor in it will be fine for the SS2?

Yep thats what you need

I can swap your current dump assembly with a Blanking plate for external gating. Just unbolt it and send it in when ready.

The oil line if its for a high mount you will need it to be in a meter long, the length will be a dash 4, no restrictors.

Not sure how everyone has good results with Five O 1200cc sidefeeds. I barely can get the car to idle unless it rich as shit.

(this is on 98RON, hoping on E85 it idles better as it requires more fuel)

On the upside, I've got plenty of fuel now. Gave it a few good hits at 1.4bar, and car pulls pretty hard. Hiring a dyno probably in a fortnight, let's see what she pumps out.

If in doubt about the flow matching, just run the next size up drill bit through them mate. Sheelberight. :P

gahhh... you bastard LOL...

tempted to convert to top feed (yes yes, I should have listened).. however on a SR20DET they work well, this is probably due to head design.. RB seems to have more material in the middle of each intake ports hence a fire hydrant fuel injector doesn't "dribble" down properly.

Thanks stao

Drove my brothers s13 with the atr28ss2 on actuator pressure 15-16 psi and goes good but he has a s15 motor and VCt still not tuned yet soon

Might get mine tuned before him

Start to strip the head tomorrow

So old tech injectors still suck? ;)

hahahhaa... I bought some replacements (actually bought 2, 1x spare)

Stao upgrade me to a atr28ss2 as part of a evaluation test can wait to put it on

Was perfect timing as I needed to replace the headgasket on my sr20det

man.. that looks sexy :)

Excellent cheers mani!

Also, any more video of your car man? I'm addicted to how well that thing destroys tyres haha

haha cheers mate, heres another one from a couple of months ago https://www.youtube.com/watch?v=AOdfjhrf9nU

No worries. Personal opinion that is one of the best turbochargers I've trailed so far on the S14. Had another customer with a 180sx reported 280rwkws on P98 fuel with full boost by 4300RPMs. Will post result once its emailed through.

Some footages from John Reco. That is the World time attach, fastest lap of 1.05 sec.

Running 700cc injectors, PFC, Our high flowed 21U R33 turbo internally gated, E85 fuel, Tuned by Chequrered tuning, Making 310rwkws @ 20psi.

is it only the 1200s that you find idle problems with? cause Ive got the 1000s in mine and even before a tune from just me setting the corrections it idled perfect like stock injectors but Im also on e85 so that might be helping things.

I've installed a similar set, however 1000cc on a SR20DET and it idled and drove well without missing - although on the rich side.

With the same set, but in 1200cc on a RB25DET they're horrible!

I would imagine on E85 it would be better as you require more fuel on idle.

Probably time to man up and go to united next weekend lol

The 1200cc on E85 worked fine on my car, apart from one seized up.

Alternatively check out Deschwerks 1000ccs. I've used three sets of their injectors and sold many with the KIA kits to China, no issues so far.

Like I've been told previously by Unigroup on s14/s15 sr20det engines the highflows have a chance of working as it hits the head ports and sort of atomizes the fuel where as on a s13 sr20det it's aimed right at the intake valves and spray like a garden hose on jet mode

May be similar on a rb25 depending on where the injectors aim

Have you ever ran them on 98 though?

E85 "should" mask up the garden hose effect as up to 30% more fuel is required to idle, not to mention more timing too.

I had similar AFR issues on my mate's S15. After visiting united and me tweaking his tune the injectors do exactly what I tell them to do (massive thread on nissansilvia.com) however without the misfire and stumbling on idle and light cruise.

On a RB25DET though they're a croc of shit with 98RON - I can lean them out but the car misses like a 2 stroke mower. Had to pump so much latency into the settings the car now just idles about 12.5 but at least it's not stumbling around.

I read up on NASIOC and guys have the same issue with these injectors on their EJs, they just can't seem to have any control with normal pump fuel and however success rate increases with E85.

So time for E85 and bye bye whatever economy I had lol

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
