Ok iv heard that the evo 10 injectors can go into the k20, heard a few lads talking about it at the garage about the evo 10 injectors adding bhp and power to the k20 engine, I wasn't sure about this however it is interesting to know, can these injectors with a re-map on a N/A K20 do that or would there be any advantages to doing this?
 
Maybe they have a better spray pattern over oem ones?

Combined with a re-map, maybe a couple of hp can be gained - i guess it depends on what other mods the engine has
 
Atomization might be better...but are they better than aftermarket injectors like RC or ID's? Doubt it.

Everyone raves about RC, but none of their injectors actually match when being tested and being new. A company I know had to buy 12 injectors (new) just to get 4 within 1% of each other for a high comp k20 turbo build - pretty shocking really..



Heres a couple of examples, their page has loads more! :((



 
I don't recommend RC injectors for the same reason as Wazer has posted. We have had trouble with them over the years.

RDX 410cc injectors would be a good choice, they have better atomisation than the stock k20 injectors.
 
the evo 10 ones r 600cc I believe or 650cc, the mods iv got are dc5 cams, skunk throttle body, rrc inlet, skunk headers, the engine is still out the car so I'm thinking of changing the injectors
 
I'm using the rdx440 injectors for the same set up as above but with a k24

Stock injectors will be fine for your setup.

Imo they are far too big for your application, at a very push I would get 410's as vtec has said. Unless you are planning to turbo in future I guess
 
Shocking info on the RC injectors. My goodness.
Ive never used them myself nor will I after reading the above. wow.
Very happy with ID's work so far.
 
what about evo ix injectors? they are like 560cc? it looks like spray pattern must be very good? also OEM injectors must be much better than RC, etc.
 
If your not sure how they will perform, or you dont wont to make decisions based on speculations then let the dyno to the talking. Never do something if your not sure about the performance

But more CC then the RDX can deliver is not neccesary...you wont win anything if you use a bigger size injector unless you have boost targets or what so ever.

make sure to make adjustments in K-pro etc whenever using bigger injectors
 
I've heard good things about evo X injectors on K20.org. As for my rdx 410 injectors I fitted them with the rest of my k24 set up and got it mapped so I can't comment on them before and after sorry
