Hi guys...I've been reading the forum for a while, but this is my first post (hooray!). I own a 1992 Mazda Protege DX with the origional engine. I'm about a step away from purchasing a 1.6L BPT engine from a 1992 323.

I know the engine drops in the transmission and mounting bolts without modifications, but what WILL have to be modified in order for the engine to work properly?

 

What you will be looking at modifying to properly run the engine are 3 basic areas:

Fuel, Ignition, Drivetrain.

You will be running larger injectors (if you go with the 1.8L GTX Motor) which will need to be supplied with more pressure or longer injector pulsewidths to maintain proper Air Fuel ratio's. This can be done by adding an aftermarket FMU (Fuel Management Unit) like the Cartech 20005 or 7. Or you can run an Apex'i S-AFC, HKS Fcon, etc... you can even install a full blown engine management system to control your fuel and everything else, like the Haltech E6K, Electromotive TEC-3, etc... You will also need to install a higher flowing fuel pump to provide the proper pressures under boost...

Ignition will need to be retarded under boost to avoid detonation. This can be done with the use of devices such as the MSD Boost Timing Retard, or the Jacobs BTM, etc... This is a crucial area to not melting your motor. This can also be taken care of with a full engine management system....

Your stock clutch will not hold up long to the abuse of 180+hp and 180lb-ft of torque. Most people prefer to run an ACT Street/strip setup which increases pedal effort slightly and holds the power. Some who are looking for major power prefer a heavy duty clutch like the ACT Xtreme or Clutchnet 6 puks. These may cause more damage than good... at least in some cases :wink:

You will also need a decent intercooler setup to keep the intake air temps down to a breathable level.. This is fairly straight forward and you should be able to find plenty of information throughout the forums on it..

Hope this helps, feel free to contact me if you have any more questions.

 

What vehicles have the 1.8L BPT engine? The 1992 323 does not?


I do want to eventually turbo charge, but I don't know when I'm going to do it. It could be as early as october, or it might not even be untill next year. So,Here's what you're saying I need to replace for the drop-in engine:

-Heavy-duty clutch
-FMU
-Higher Flowing Fuel Pump
-Intercooler setup


anything else that should be considered before I get all of this done? Does anyone know anyone in the Dayton, OH area who has experience with this mod/engine?


Thanks for the help!

 

running this engine isnt a problem with the F tranny from the DX right? or is it necessary to change tranny to the G?
