Post Ultimate Racing Fuel injectors w/ top feed rail kit for STI

Has any one been using ultimate racing's 785cc fuel injectors with there top feed fuel rail and wiring kit? How did the injectors and the fuel rails work out for you? Any problems with the install big or small? How was it wiring them up?
How was it tuning the car with them as apposed to the stock ones? Any and all information would be more than greatly appreciated! The reason I ask this is I went with the perrin side feed fuel rails for the sti with there modded injector and found out that there fuel rail setup was pure crap and I really didn't want to put the stock rail's back in (i shouldn't of even took them out in the first place) and was thinking about ultimate racing fuel setup. Thanks -Dave

i have 'em. i like 'em. the install was fairly straightforward. it was my first time removing the intake manifold, so it took some time to get the whole job done, but yeah, just make sure you take your time to do everything right the first time.

I've got the same rails/injectors, but have not yet installed them. They look fairly straightforward, but as the above post mentions, you'll have to remove the intake manifold. I'll be using them with the sr55.

happasaiyan, where did you mount the resistor pack?

there is a bolt on the passenger side on the opposite side of the fender. right in front of the FBC. i screwed the bolt in holding the resistor pack in.

to make it more stealthy looking, i went to the local hardware store and bought some black plastic wire casing like the oem stuff and put the wires in there. then i electrical taped them together. you couldnt see it if you werent really looking for it.

maybe ill take some pics of the engine bay and post them later on.

Does it provide enough fuel for you setup? What horse power do you think they will max out at? Thanks -Dave
