How Much Flow Will 480cc Injectors Support On Rb25det?

[Skyline1989]

As title says,

i'm in the market for new injectors for my R34 GT-t but i'm not sure which size i should go for.

i'm not sure if 480cc injectors would be adequate. i would like straight drop ins

power figures i'm chasing would be between 270-290 rwkws. Preferably without using a FPR

Any help is muchly appreciated,

thanks guys

A decent fuel pump and a set of 480cc injectors will be able to do that power level fairly safely

And yes, major difference between r33 and r34 injectors

is anyone else 100% sure my car will crack 290 rwkws with 480cc?

had a mate that only made 245rwkws on a mainline dyno

cheers for the help guys

yes... i have 555's runing 311rwkw on e85 and that uses 30% more fuel than PULP

i went 850cc for a big safe net lol. and its was only $40more im running 270rwkw and running at around 65% duty cycle

480cc is fine and will make that power no problems

putting in double the size required injectors is a stupid idea even if they are the same price (usually they are)

[GtstCoupe]

well is a good thing i did not put in double the size then paul lol

mine have been great , if you go big make sure you tunner is confident in tunning then, really if there good

then can make it runn like a kitten on 1000cc, you get the idea lol

^^^^^Do you monitor your afr's?

mate has 1200's in his wrx, runs like standard...

[Skyline1989]

only a bit confused because a mate of mine made 245 rwkws on 480cc's with a mainline

and they reckon the fuel pump was still A-OK

still abit weary of wanting to install 480's

[joeyjoejoejuniorshabadoo]

on what turbo, afm?

[Skyline1989]

HKS 2835 with .68 rear i think that's the only size they came in

Z32, Power FC, custom dump, custom intake pipe, nismo pump
