Best Injectors For A R33 Series1

[mat277]

Hi just wondering what is the best upgrade injectors for a R33?

[R31Nismoid]

5000cc, made in Russia.

Come on mate, how can there be "one best" injector when set-ups vary from 200rwkw to 600rwkw?

Insufficient detail to answer such a question.

how much power are you planning on making? and on which fuel?

I would be really happy to get about 300kw at the wheels and be running premium fuel. My motor has been fully rebuilt, i have adjustable timing gears, bigger fuel pump and im about to upgrade my turbo. I just want a slightly bigger injector than standard. I have an R33 GTST with an RB25DET in it.

555cc if you go a 3071 or smaller

740cc if you go a 3076 or larger

740cc minimum if you are going to run e85

1000cc if you want to shoot for more power on e85 later on

These are the ones you want:

get ones with a decent spray pattern as well, don't just look at the cc rating.

Nismo 555 you will get away with but considering 740 arent that much more its better to go them since you might go e85 and since you have a built motor might want to push more later.

+1 i'd be looking at nismo 740's

Which ones have good spray patterns then?

I mean i got these sard dual spray ones (designed for JZ engines) that dont seem to have a spray pattern really they just shoot 2 huge jets of fuel out, have read somewhere they can spray into the walls on RBs ..Dunno if thats any good or not but they work ok..Definately can supply a heap of fuel..

I wouldn't know to be honest, I haven't been injector shopping yet. But I do know that there is an appreciable difference between cheap and good ones.

Start googling for reviews and tech articles, that is what I would be doing.

Not to worry, I did some googling when i got them but didnt find alot, they're already in the car and working fine, if they stop working then i will worry..
