Hi all,

I have a r34 gtt with a gtx3076, link ecu, Walbro 450lph fuel pump ect.

Anyways its time to upgrade the injectors, I want to put something decent in which will allow me to run E85 down the track without needing to change injectors again. I will need to upgrade the pump & lines when the time comes.

I am looking at these deatschwerks 1000cc E85 compatible injectors:

http://www.deatschwerks.com/products/fuel-injectors/sport-compact/nissan/skyline/neo-rb25det/1998-02-neo-rb25det/17u-06-1000-6-detail

Now the question is, are these going to be ok to run 98 pump fuel through without having a shocking idle & part throttle drive ability?

If its going to make the car real rough then I think I will need to go smaller now & then upgrade when I do want to go E85.

Sorry if this is a newb question, I have done some searching but cant find much.

Thanks in advance.

They are a high flowed Bosch 550cc injector, so there are better options for 1000cc injectors available now.

Thanks for all the help.

Sub boy32 are you saying those deatschwerks are actually high flowed 550cc bosch injectors?

Wheezy what brand injectors did you fit?

What sort of power are you guys running on 98?

I wouldn't stress too much, most of the 1000's sold these days are 750cc injectors with the pintle cap removed. They spray perfectly well, and work better for e85 imo than the long nose 900cc injectors he linked, and cheaper.

Marketing hype...

With the dollar the way it is, locally modified and warranted injectors are a much smarter option, considering they are exactly the same Bosch injector. Unless you like paying the ID tax...

The new 1300 and 1700s from ID are a whole new ball game though, internals are made inhouse with BOSCH motorpsort department... they are streets above the rest ATM.

The 1300's are only available through ID, but the 1700's are sold locally also. Not cheap though.

I was hoping to try them out in the evo but the 1400's I have currently will be fine with the Haltech elite i'm sure, and nearly half the price.

I wonder how much different they are from the stainless Deatscheworks...

We have done quite a bit of injector testing.

The spray pattern between a high flowed 550/750cc injector compared to the ones I have linked to are night and day different

The Bosch 1000's are designed for Ethanol, where as the 550s weren't......

High flowed injectors were fine when there wasn't the correct sized injector available.....but now Bosch makes 1000's, 1300's and 1650's straight out of the box now.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
