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.....

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.

      Ethanol Content Sensor - Always at 11%?

      I can't speak for the US, but for Canada as I mentioned above, all fuel gases contain ethanol. We have regulations for E5/E10/E15. Each province handles it differently but basically any fuel gases sold must be E10 and slowly increasing to E15 by a certain year.

      Blue slip

      By Stringycheese · Posted

      Hey guys, Purchased and drove up new wheels from Vic last weekend. Car never been registered in Aus before. Only thing was aware of was pod filter which reverted back to stock. Went to get blue slip in western sydney. Everything with car fine (compliance etc) and knocked back for coilovers. Was told illegal and need engineering cert. Called the certifier they recommended and was told at min $1000 to certify them. I was then told HP can STILL defect you even with them certified. All this was news to me. Is this just a case of deal with pay the $1000 and run the risk? Kind of nuts given the amount of people running with coils I know of. No one I know has OEMs to use to pass, either.

      Welcome mate. Best Stagea is best Stagea. How is it driving a correct hand drive vehicle driving on the right? The Japanese do the opposite here and they've made parking boom gate ticket things on both sides to cater for LHD and RHD cars, as there's so many of them (mostly German but there are quite a few American cars too).
