isuzurob, Sounds like a similar setup to me,,, mine is 12mm pump, Toyota 3.7 direct injection cam plate, and mods to boost compensator , and pretty much everything else that can be tweaked,,, double factory fuelling ,, Turbo is Isuzu 3.1 exhaust housing and turbine, Subaru core, and VF10 comp housing machined to take hilux 3.0 upgrade billet wheel,, 44/58mm ... we are currently working on the best injectors to suit the 4jg1 pistons,, And the best position in relation to the bowl,,, The 4jh1 injectors have worked best 1.0mm closer to bowl than stock,, Am at 100kw and 360NM (at the wheels) so far,,, but def more to come... as these figures were achieved at only 2700 - 2800rpm,,,, falls off after that What mods did you do to your injectors? We plan to try 4jb1 injectors too,, and possibly a 4jb1 standard pump just to see what happens,,,
