Nismo 550/555's (cant remember which), i had 740's... never missed a beat

Drop in, no problems.

There are other cheaper ones, Deusch works or something couple hundred cheaper

Sards require a bit of farting around so the cost saving isnt worth it

The nismo inj are pretty cheap now as apposed to probably a year ago.. i got a quote from perfectrun.com.au for $800 to my door.. so in effect if your going to do the works (well not the works just big power) then they will be good for you.

Have many people used the deatchwerks injectors? Just wondering wether its worth risking a motor for saving 2-3 hundred $$ if shit hits the fan like a faulty injector...? Can anyone shed some light on this cos the deatchwerks injectors have to be the CHEAPEST ones i've seen... by far unless its 2nd hand lol

They use the Jecs injectors i think... the standard type nissan inj. ( I could be wrong )

I have a set of 555cc injectors from Deatschwerks. I have read of at least 3 others on this forum using them as well.

Mine have been running for about 2 months and haven't had a problem. The car hasn't been tuned for the new turbo or injectors yet, I just made the appropriate corrections in the PowerFC. I haven't seen them go over 70% duty cycle yet, so they will definately flow enough for my power target.

They re-use factory injectors and replace the main components (buckets and pintle caps I think). The price also includes new o-rings, and you get a pretty flow report with specs for each injector :happy:

Having said that, after reading that thread a couple of weeks ago on shaving injectors, I wouldn't be suprised if that is all it really is, just a high tech version of.

cheers i think im going to give deatschworks a go, yeah 555cc injectors will be fine for my power levels, how long where u waiting from payment to delivery?

Around 7 days from memory

Yea give or take around 7 days... I purchased a set then i wasn't confident in them so i sold em LOL

It worked out cheap... really cheap especially with the rebate! if your standard injectors are good like Lazy-Bastard said you get $25 USD back for em each... works out to around $150usd, the exchange rate will give you about $200.. so in effect your paying around $350 for the injectors... not bad ey?

I just want to know everyones personal experience with the inj, they use the Jecs inj like Lazy-Bastard said, but hmm... i just dunno... I wonder what the moderators think about these inj and the risks involved (if any)

I just recieved my set of Deatschwerks 555cc Injectors on Thursday. took less then 7 days to arrive and will be getting them fitted and tuned using a Haltech E11v2 later this month. I will post up the results including dyno print.

Cheers

Like i'm sure they would be fine with the tune and the results will more than likely be as good as having sards or nismos in there, but what i'm concerned about and i dunno if anyone can vouch for this is wether they will go the distance? i've read the jecs ones leak around the seals or something like that, some people complaining and crap but yea i suppose its pot luck with alot of stuff you buy... even rebuilds can turn to shit cos the tuner/mechanic didnt take the right measures for the abuse the motor is due to take... which i've seen with a few workshops in melb which friends have been to with their cars...

But deatchwerks always say "if there is something wrong with them just send em back to us" and they will replace them.. they're REALLLY REALLY good to deal with and they arn't ones to hide even tho they're in oaklahoma usa.... but eh i suppose its only worth a try

Deatchswerks have supplied thousands of automotive customers through out the years and they seem to be providing a high quality, reliable and excellent priced product. There are many 800 - 1000Hp machines using Deatschwerks 1100+cc high flow injectors without a problem...

When ng on the "shaved" injector theory, the standard RB25DET injectors flowed at approx 720cc with the entire pintle cap removed, therefore a 550 to 720cc highflow is more then capable for the stock injectors.

Cheers

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
