240CC injectors won't produce the amount B20 petrol wants for maximum horse, go for a larger one.

Go for large injectors like what honda76 said, b20/h22 should be enough. =D

Engine with lots of petrol in combustion better than lack of petrol in combustion. Saving a little bit in injectors might cost you more when not enough petrol during combustion, thats it. =D You gonna cost more maybe buying another build engine?

If i'm wrong, please correct me. :P

searched the internet..b20 injector also 240CC, that is no difference from a b16 injector. So can just reuse back b16 injector?

Better upsize yr injector bro. If starve of petrol at high rev most likely will blow yr engine. Smaller injector will not be able to provide enough petrol in physical term. Lets say u use a vafc to tune, u can keep adding fuel, but the injectors will never be able to keep up.

it will be better to change if ur b20 is with VTEC...can get slightly bigger cc than use piggy bac to tune it...b20 stock use 240cc 2lite engine but dc2 use 260cc 1.8lite...

u think 240 enought for ur engine?

the injectors 240cc will be enough for low power application. meaning normal driving.

what the guys means is that with high power, high rev prolong drive , it will hurt your engine, starving it with petrol.

change to a aftermaket injectors or at least get the prelude or evos to avoid trouble.

Can increasing the fuel pressure to > 2.8 resolve the problem? Read from internet some people so that without replacing stock b16 injectors.

To further squeeze hp from the engine, do u know whether saturation or peak/hold injectors is more recommended?

Y do you not want to change the injectors? When there is a tendency to blow the engine?

the dyno ppl recomd a bar pressure at 3. at least i think it a safe threhold. technically i cant explain why though.

some techincal bro will explain the peak/hold n saturation injectors portion

b16 injectors are good up till 200 bhp. unless yours is stock b20 , it will serve ur purpose very well.. oh , please remember fuel pump as well if you are on high b20 applications.

eg uses high impendence injectors. can't rmb if it's peak/hold or saturated. if you use a low impendence one, you'll need a resistor box. i'm using wrx 440cc blue injectors with a resistor box.

RC is one of the more well known brands out there and they have high impendence injectors for EG. plug and play. just have to change the injector clips.
