Hi ppl,

I am looking to upgrade my injectors. Current setup is good for 250rwkw to 270rwkw. I have been searching high and low.... Nismo 480cc too small capacity for my set up and Sard 650cc has been said not to be too good.

So i have currently been looking at the Power enterprise 510cc injectors. it says:

510cc ER34 part number: TH510NZ High REsistance and 8 nozzles.

*8 nozzles? wow?

Nismo 480cc comes with 4 nozzles(holes-are they the same) if i am not mistaken? Does this means i can run at higher output or better flow/spray??

besides the Power Enterprise ijnectors, i am also looking at the HKS 680cc injectors(low resistance) need the HKS fuel rail and dropping resistor.

any one had experience with this two brands of injectors?

ps: I have got no idea what are the power output of any injectors. eg: nismo 480cc good for how many kw?? 250kw maxed out??

why don't you just put in a set of 800cc injectors?

I've used 1000cc injectors in RB20's and had them idling as good as factory.

RB25s are going ot be the same.

I also have 555cc Nismos running 315rwkw, and they are at 80% duty cycle at standard fuel pressure. (Standard regulator)

i;ve also been askin similar questions recently but havnt got an answer..mods are in my signature and getting pfc monday, i aiming for 300+ hp, wat injectors do i need cc rating and do i need an external pump??

hi ppl,

Thanks for the reply everyone.

i have read a few post on SAU and some says they are maxing out on 480cc injectors around 250kw. was looking at doing it properly once and finish the car.

any one has ideas on the POWER ENTERPRISE injectors or HKS injectors? anyone had previous experiences?

mate if your that worried about them maxing out... I have 230rwkw for the moment and I have nismo 740cc injectors flowing at a max of about 54%.... they go straight into the standard fuel rail and she idles fine. :( PLENTY of room in the future :P

I get what you meant. nismos only have 480cc for the er34. and i was looking at bigger injectors for long run just incase of adding a few more stuff to the engine.

and you guys should know its a pain to pay for labour twice when you can do it once.

i think they are made by Denso. *correct me if i am wrong.

But it states 8 nozzles on the injector, meaning better spraying pattern?

Just need to clarify if the injectors are as good as the nismo ones.

Still no one have ever used Power Enterprise injectors?

    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
