is it worth it?

Probably no, GTR injectors (444cc) are the better choice ($200-$300 for a set), they are top feed and just bolt straight in, and just require a resistor pack because they are low impedance

No it is not worth it. When you highflow an injector, most of the time the spray pattern goes to shit and it can mean death for your engine....especially when you start pushing the hp.

It's an extremely stupid idea and the cost of new injectors is not that bad. What's the cost of a new engine?

And I don't think RB20 injectors are able to be highflowed anyway.

rb20 injectors cant be done properly, we get CREATD to do ours (R33) spray pattern is the same as stock so there is no issues there. Of course highlflows have there place, but not in all.

Got any more detailed info of that Trent? (r33 items?).

Not saying i don't believe you, but have you got any spray pattern photo's under various pressure's from base, +10 & +20?

Not that i would use them, just for everyone else to see a bit more indepth information to help with decisions :action-smiley-069:

i'm pretty sure if you wanted to buy some (speaking to prospective customers) CREATD would show you in real time in the test machine like they did for me, i was 100% against highflows until i saw their work...

There are time and places high flows should not be used i and i whole heartedly agree but for guys on a tight budget where 250-270rwkw is the target on a highflow or chinese turbo i cant see a problem, unless the person selling them is pushing them as "the only" solution.

To me running the best brand injectors then using a cheap ecu to control them defeats the purpose, in fact using a decent ecu with highflow injectors yeilds better results.

I suppose what im saying is that everything is relative. Relative to budget, application and execution.

Its too easy to get hung up on the one particular thing, when really the whole setup should be considered more important.

Well ye real time - but not everyone is in the Northern burbs of Melbourne :action-smiley-069:

Would help to dispel a bit of conjecture on the topic.

Perhaps if someone uses CREATD they could get some further pictoral information to add to a "high-flow injectors 101" style of thread about the topic?

Just gets other users from interstate/overseas some useful information to their decision in the overall scheme of their setup/budget.

Try it and see how you go.

Don't point the finger when your engine goes bang.

We test, flow and clean injectors every day, injectors are made to a tolerant, there designed for there intended purpose not to be modified.

When you drill and change the design of the injector the pin-til end can get damaged which will upset your spray pattern = fuel mixture into cylinder.

We have seen a lot of "hi-flowed" injectors that when RETESTED fail.....

yep and ive seen lots of brand new siemens injectors perform terribly.... as i've said everything is relative.

ive been running hi flowed injectors done by my mate for 2yrs now, just shaved and recapped rb25 injectors 350rwhp 20psi and 60,000kms later 9ltrs/100km on highway.. never had a drama..one thing tuner said figures change slighty on idle cause the spray pattern is never the same.. but u get that who cares :D

thanks for all the feed back guys!!! im not looking for massive power i will be more than happy with around 220atw

lol, then why do yo need to highflow the injectors?

Oblivion makes 351 hp at the wheels on stockos. Plenty left in them too.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
