Injectors for 4agte?

**Poggy** · 12-03-2009, 06:48 PM

Hey everyone, i need injectors for my 4agte, heard about the 13b rx7 injectors, wondering if anyone else runs them, and whats needed to fit them, also they are 550cc?

I think there are many different types of 13B injectors.

I had some 440s that fitted fine but needed different plugs. I've heard bad rumours about their spray pattern, but that was just on the internet, so who knows.

Other options include 7MGTE 440s. Straight fit. No mods.

In ran the 550's for years. Top injector!! i had no issues with them what so ever. I had them cleaned and checked when i bought them as you would....... and never looked back.
Spray pattern is fine.

It is the throttle body injection early ones that have a poor spray pattern not the multi point ones

Thery are good for 250 odd rwkw at 55psi pressure too.
Injectors are a purple colour. The only thing needed to fit them is to change injector plugs.

ive got rx550cc purple injectors in and my idle is pretty crap, they must be the old ones. I'll tune idle with the tps instead of map and it will be fine, other than that there awesome and bolt in.

are the last four digits on your plugs 1370 ?

30psi are those the injectors in your picture ?, myne where like a dark purple.
