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:

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.

      My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered

      No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
