What are they? coz was looking to upgrade the ones in my road car

[touge_ae101]

what are they in terms of??? i will assume you know what they do in terms of injecting fuel into the engine.
this is what they look like

obviously there are slight differences between each type of 4age - BT, ST, 16V and ze but i think you can find that info for yourself if you look.

if it is a road car it is not worth upgrading them as unless you have done a serious amount of modifying they won't be the thing that is holding your setup back from making more power. 4age injectors are quite big for their application.

to give you an idea of what kind of modifications you can get out of stock 4age injectors, read up on BZR4AGE's build thread. fully rebuilt engine with toda pistons etc, nasty amounts of compression, 304 cams and pushing out a healthy 135ish kws and not in need of upgraded injectors.

this is my take on the whole 4age injector topic. anyone else please feel free to add more/tell me if i'm wrong.

You can put some 550cc RX7 Injectors in. They'll bolt straight in with no mods needed, and instantly give you about 50% more fuel. I run them in my road car, but I occasionally drag it too.

20v injectors are 295cc or something which is a pretty decent size, the early 16v from memory are 185cc? Is it 16v or 20v and what mods?

Use injectors relative to the power you're making. You won't get any benefit from larger ones if everything else is the same. In fact, it can leave you worse off, as larger injectors don't atomize the fuel as well when injecting lower volumes.

What ECU do you plan to use, as if you go to larger injectors you will need an aftermarket ECU.
