no probs fella sorry for being a bit harsh,
until you have done the mods yourself, and then pushed them to there limits, i wouldnt type posts like the one in question as there are a lot of new people on here these days that dont search the forum enough to find the true potential of each given mod!
i would hate for a new skyline owner to read your post and rush out and purchase a walbro thinking that it will keep up with a 044. then blow there engine.
i am a big fan of the walbro pump for its cost and size it does a hell of a job. i made it to 270kws at the rears but the afr was real ugly and the 550 nismo injectors at around 90% duty cycle.
by changing to a properlly mounted 044 my fuel flow and pressure both increased to the point where now im at 300 kws and the injectors are only running at around 70%
i hope this helps and just be carefull once you get past 250 kws.
i now have a forged bottom end to prove it...
one last thing my 044 cost me $275 plus another $50 of fittings, filters, etc
my bottom end cost me lots more....
dont scimp on the things that keep your motor alive...
