4age bigport ( injectors replacement )

[ae86]

hey guys was wondering what injectors i can move to for a standard bigport, my injectors are a bit noisy so i want to change over to something, prefrably if im able to get something newer id be happy with that so just seeing what others have changed to before i jump on the bandwagon

if you change the injectors to ANYTHING except stock then you need an aftermarket ecu to control them.

there are many injectors that "FIT" but if you just plug them in they will be different sizes and thus wont work properly with standard ecu.

if you think yours are stuffed then pick up some new ones (i have some if you want to buy them) then take them to an injector cleaning service where they will run them through their awesome machine, and change all the seals. you will then have a brand new set of injectors to use.

btw all injectors tick....its when they dont tick you have to worry.

thought maybe smallport ones might work to a slight difference or something withoute having to go aftermarket all good thanks for reply, il get in contact if i get more money soon

LOL

what exactly do you smoke that makes you worry about injector ticking noises? i mean .. if you can hear that shit over your exhaust something's wrong. or you're a dog in a human body?

Injectors usually make some noise. If anything take them out and have them cleaned and flow tested. Small port are like 210cc each over the 182cc that bigport is. You will be over fueling like crazy plus the plugs are different. (could be wrong aobut injector sizes, been a while since i looked into it)

Clean and flow test would be best.

ta, well yeah i can hear them over my exhaust when idleing (fairly sure and hopeing its injectors) and my exhaust is trd copy extractors with 2.25 catback its not really silent either, so indicates how much ticking noise there is, btw thats with hood closed.

[ae86]

just had a listen then, sounds like the most vibration / noise is @ bottom of injectors
judgeing by the way seamus told me to have a listen ( screwdriver to the ear )

lifters maybe?

i mentioned he *might* need a valve adjustment, especially if he can hear the noise clearly over his (supposedly loud) exhaust

I second this
