Default DeatschWerks 950cc Injectors?

I currently have a set of DW 850cc injectors installed in my car but I plan on upgrading my motor in the future and will surely need more fuel. Does anybody have experience with the DW 950cc injectors? I really dont want to totally redo my fuel system since I already have rails, lines, TGVs, etc wich are all setup for side feed injectors. Thanks.

pretty sure DW stopped making the 950's. unless they are like a special order or something or you buy them used from someone.

06+wrx injectors flow about 950cc when modded.

Side feed DW950 are a freak occurrence. Basically when DW has a large production run of injectors a very small percentage of the ones that should flow 850 end up freakishly flowing more. Those injectors are flow matched and grouped together for sale as "950's". For every couple hundred 850 injectors they might come up with one or two sets of 950's. So long story short they aren't exactly readily available. You just need to call DW and see if they have any available. I run a set in my car and they are fantastic.

You could always up your static fuel pressure to get the extra flow.

I actually have a new set of 950s that I purchased off a nasioc member. They included a specs sheet that shows ~950cc but for some reason I am skeptical of those numbers. I am contemplating sending them out for 3rd party confirmation. Does anybody think that confirmation is worth it or should I just trust DW?

DW doesn't mess around. That value is accurate!

Is this true? ... Cuz i thought nobody makes side feed bigger than 850cc, I want to run E85 and i been looking for bigger side feed injectors but no luck.

I know that 07 Sti is top feed so i was looking into that as an option cuz with top feed injectors there is no problem getting bigger injectors.

If not true can someone then tell me how to do a top feed convertion on 04 Sti... Thanks

Sorry to bring this post back from the dead - but I'm wondering if anyone can bring some more info about these injectors.

I bought a car w/these in and we're having some issues tuning them. Basically, the car will idle rich at times and learning fuel trims will be pulled -15%. AFR will sit anywhere from 13-14.5.

Are these injectors dw850ccs in all respects other than the fact that they just flow more than inspected? Has anyone else had any problems tuning these?
