Im in the process of putting my 6 port turbo together and i cant find any information on how to assemble the exterior of the engine. Im installing the injectors and i have purple TII injectors and the stock red ones from the TII as well. Which rail do they does which go on? top or bottom. Im also trying to figure out where the hoses go on the top of the oil injectors. Any help is appreciated pics would make my day. Thanks

 

Foxed.ca
factory service manual.
..
and depending on what your harness is and the Injector impedance is,you should match that to your ECU.
check the Part numbers on the injectors to get the Impedance..The Frequently Asked Questions UP TOP of the section has the info about the injectors.
You can't use HI's with the Resistor pack,or LO's without a resistor pack.

 

Thanks sooo much, will it be different because i have smog deleted?

 

I will be using the stock injectors for now, i have the injector harness marked for which injector i just forgot where which one goes on the rail lol.

 

Ok i looked through the Factory service manual in the assembly section, and i just have to say that mazda did a terrible job explaining stuff. They just say put this there hook that up. They are not very specific at all, oh and it never says in the book which fuel rail is primary and which is secondary and which injectors are which. Could still use some insight on that. Thanks

 

Primary injectors are the lower ones that are right next to each other. Secondaries sit up a little bit and feed into the lower intake manifold. Maybe it's just me, but I found that in the FSM as well...

 

Secondaries..TIP: the SECOND you take the upper manifold off,you SEE them!

 

so you're turboing a high compression engine and don't even know the orientation of the injectors.... this is going to end badly.

 

 

Oh my dear Clarkson... Let's avoid setting something on fire here.
