ok guys its time for some new injectors that are bigger than 370cc. im unsure on what size cc to choose for my application. some of you may already know some specs on my engine and that i would be very happy to sit on 400hp but would oneday like to bring it up to 500hp after im comfortable with the power. so what injector size would suit ?
If you want to save yourself some cash but and are not doing anything serious then skip the 300 degree rails. 400+RWKW on stock rails mate must say something ... Unless you want to go to series 2 injectors otherwise as abz said you have the common choice of Nismo 740cc . Cost effective choice is the 750cc Jecs from coz which are a direct drop in to S1 rails and at $475 you can't to wrong with them. I use these myself and have not had a issue with them
im leaning towards s2 pintless injectors, and if u can get 400+rwkw on stock rail then ill keep using them
Good rule of thumb 400hp = 400cc more or less. If you don't plan to exceed 500hp perhaps Nismo 555's?
so having lets say 600cc injectors and running 400hp would be fine? like no loss in power or fuel econ (i know fuel econ should be the last thing on my mind with high hp)
Nismo 555 series 1 fit the bill. Why? You don't need to change your connectors and they drop into the rail without any fisd
Yes, that will be fine. Doubt you will have any noticeable difference in fuel economy from changing injectors. At cruise it will still work in closed loop.
i want s2 as i hate those s1 connectors and i already have a sub harness for my injectors so its simple plug out old s1 sub and plug in s2 sub. i think i know which ones i want now, ill be most likely getting them of another forum member here so thnx heaps guys this info helped
Don't the S2 injectors? Require some machining to fit? Nismo also make a S2 550cc injector. Well, made by JECS anyway, branded as Nismo.
