Hi guys

looking at getting DeatschWerks 1000cc Side Feed for my r33, I have tomei 740cc injectors on currently. Is it simply just unplugging my current injectors and plugging in the 1000cc ones? Also would they foul or have a problem with my plazmaman forward facing plenum?

Also best place to purchase them in Melbourne ?

The Tomei 740s should support over 350kw so beware your reasons for changing..


As for where to buy the Deatschwerks the cheapest place will be their website.


If you need 1000cc injectors and are looking for a buget option try the Five_O motor sport injectors. They are similar in principal to the DW items and also work well. I am using the 850cc items and they are faultless.

You can buy a set on ebay for under $700 delivered, direct bolt in for an RB25.

How would these work five o injectors work?

Are they a simple plug in and play?

The 740cc injectors I have now were apparently going to max out at 320 on e85 according to my tuner

Those injectors have been used by lots of people and work well. Most results I have seen are E85, so I cannot vouch for how good they are on petrol.

Yes they are a plug and play. I would consider these to be a mid spec injector, they aren't water guns but they aren't no injector dynamics stuff either. They would be as good as the DW in my books.

That being said if you are running a powerFC or Nistune (or other entry level ecu) you may want to consider a smaller injector to retain idle quality. If you are running something like a Haltech, Viper, Link or Adaptronic I would not be concerned and would say go for it. Otherwise stick to 1000cc as a maximum (I went 850s specifically because I am running a Nistune, otherwise I would have got the 1200s).

    • 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
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
