hey guys
im after some help on choosing some fuel injectors for my beastie. i have standard 440cc injectors, but looking for something round the 600 - 650 mark i think.
trouble is i dont know which to purchase, with so many choices (low and high impeadence, top or side feed, twin or single spray) its proving more difficult than i first thought

please help!

Assuming you have a GTR

You want Top feed - low impedance injectors

Don't get too caught up in the spray patterns gimmicks, just go for a named brand.

Standard fuel rails accomodate 10.5mm necks, however some injectors are 11.0mm in diameter, and I believe some are inbetween (10.7??).
You can force an 11 into the 10.5 rail, but it is best to have the correct rail to suit.

Nengun do a large range for reasonable prices. Good Luck!!!
