Hello

I learned about 550cc injectors made by a comapny called Deatschwerks. I tried finding info about them on the web and cant find many reviews. I have read that people use them but no one has really put up a review about them.

Does anyone know if they are good injectors for the rb20 or should I stick with Nismo, Sard, or Tomei?

I got the 444 from them. The flowchart that came with mine said they're matched around 458cc.

Really noisy, the idle is a little more erratic than with the standard ones but nothing to worry about, AFR are stable on idle, cold start or hot start are as good as standard.

No problem so far with 10 000 km on them on P98.

The only downside is the noise, if I had a quieter exhaust the only thing I could hear would be them.

Double check the latency, I chose the 444cc because of it, the 555cc latency is almost two times longer from memory, and I didn't really need much more on P98 anyway.

On E85 I would buy the 650cc directly.

They come with adapter plug so they're really drop in.

Just excite them with a battery before installing them. I had to excite one directly from the battery to get it to open. Then it worked like a charm.

I purchased mine directly from their site.

Really? Really?

Their sidefeeds are as good as water pistols, similar to Five-O Motorsport Garden hoses.

Since its a RB20 I would just go EV14 or IDs if you have the cash to burn.

Im using their 700cc. Noise is about the same as stock GTR. They are a touch fluffy at idle, but a

power fc idle reset got rid of most of it. Pretty common on any aftermarket injector larger then stock.

I am of the opinion that they over rate their injectors

I have their pump as well and that has been tested and around 10% over rated- although they might test with no lines, I tested in the car. Pretty stupid to rate a pump without lines

Maybe alter the search parameters to "hydrolock, Deutschwerks" and you should get some hits.

Same goes with Five-O Motorsport... I made the mistake of buying a set, recently just spent a kidney new injectors.

However being a RB20DET, and with your power goal in mind.. Stock 444cc GT-R injectors would be tits.. drop in, wire up resistor pack, rescale and off you go

I have a set of Deatschwerks 550s in my car now - have had them for about 5 years and they seem ok. However I believe they are just "remanufactured" Nismos or something and when I upgrade I will be getting IDs or Bosch or whatever they are.

DW, Five-O, ANSU, all they do is get a JECS injector and grind off the 4x hole tip which helps with the spray pattern. They then carefully enlarge the remaining single hole to increase overall flow.

I've had a look at both side feeds, and I actually own a set of Five-O and how they're produced are identical... If you look carefully you can see grind marks.... it's sad.

I have them and a pump in my old rb20 in the 32.

They seem fine, im running an rb25 turbo at 14psi and Nistune as well.

182.8 kw safe (a little rich) tune.

The best thing about them is the ease of install, they just go in like Nissan parts, no fking around.

You wont need to worry about correct resistance like if you get gtr injectors.

You get a test flow chart and spec sheet for your tuner.

So... cheap, maybe crap quality like others have said, but ok for small goals, and very easy to install.

It all comes down to the old questions of your goals and budget.

Soo much miss information here.

DW are not jecs not even remotley close. They are bosch.

They do not have re-drilled single holes and do provide a accurate spray pattern.

However this may be true with other brands mentioned.

My Dw have been perfect so far.

I had no difficulty installing.

Tuner had no probs what so ever, neither has running idle through to Wot.

      R34 GT-T cycling ABS pump

      This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.

      Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.

      The downside of this is when you try to track the car, as soon as you hit ABS you get introduced to a unbled system. I want to avoid this. I do not want to bleed/flush/jack up the car twice just to bleed the f**kin car.

      But again, the engineers said your cast aluminium would be fine based on the load that would be stretching that section. Same load stretching the bolts in a flex (not the twist), with a much smaller cross sectional area than the original part you've broken. It's why you'd need to be using higher strength bolts, but that's just making up for the strength you lose with less area...

      I am truly amazed someone on this planet was able to cycle the pump using a scan tool. I've always ghetto cycled them on Nissan 90s shit boxes by slamming the brakes and pulling the handbrake to agitate the rear wheels enough to cause a speed difference
