Fuel Injectors 740Cc - 850Cc And Fuel Pump

[Mick_o]

Hi guys im looking to upgrade my fuel system for E85 in my rb25 looking for a setup that can handle approx 300rwkw just wondering what injectors have the best spray pattern and are obviously suitable for E85

also after suggestions for a good fuel pump? easiest installation is another factor that must be considered

Id appreciate any feedback and some tech on the reasons why i should use a specific injector and pump for my setup?

Injectors anything 500 or over should be fine although having said that ID1000s are very popular and leave room to grow!

Fuel pump Bosch 044 in your tank will handle 300kw.

Ye nismo 555 will get you there or go bigger for more room. Pumps if you want drop in go the nismo or if you to go down the surge tank route single 044 will do.

I've heard the nismo injectors spray pattern isnt that crash hot and i would of thought 555 nismos would be too small for E85 hence the reason im selling my 550cc sards for 740cc minimum. Has anybody used the Power enterprise 850cc's? Do the larger injectors idle ok? I have seen the ID2000 in a 120hp Honda integra behave like standard but i am liking the idea of direct drop in units

nismo injector spray patterns are fine. They are just a rebranded denso injector. It's actually the sards that are a bit ordinary as they are (or used to be) single pintle.

Nothing wrong with the PE injectors and they'd be my pick for e85 in an rb25 with your target power.

ID1000 and 2000 injectors are good things, just a bit of extra work (and cost) getting them in an rb25

Does anybody know who would have a good price on a set of the 850cc PE injectors?

nismo spray pattern is fine as said. they also make 740s for rb25, not just 555s

Power Enterprise and Sard repackage the same Denso injectors.

[Mick_o]

oh ok so the sards are cheaper for the same injector? cjmotor claimed the sards were not suitable for E85 but the PE were!

Ill prob just buy the sard 850cc then then

Ok so i have bought 850cc PE injectors and a Tomei fuel pump and nismo regulator hopefully that lot will feed my lil RB's thirst for E85
