Did some creepin around the car looking for things in need of correction. The rust is still not very bad considering. First, these fakie strap on pedal covers have to go. They wiggle around and look like crap, GONE! Now, let's check the basics. Fluids look topped up and belts are good. This engine has a double pulley on it so two belts running from the eccentric shaft across the water pump and around the alternator. The air pump is undriven.
Question: Other than not wanting to run the air pump, what reason would keep you from keeping the double pulley, but running a longer belt so the front belt could drive the alternator AND the air pump? There would be less belt surface in contact with the front pulley groove on the alternator and the air pump would also get less traction, slippage?
I want to keep this car fully legal so if I could put the air pump back to work that would be desirable, but I know there is a legitimate reason why the double alternator pulley is so commonly used so I'm not taking it off.
Now, let's check the fuel system and see if it looks weak. Visual, yup, that filter looks old as f***; I'll definitely be replacing that. Go around back and yes, the pump area looks like the day Mazda put it together, no mods. I'll get in there with a volt meter and see what she's getting for moving electrons.
Back under the hood, oh look, a Knight Sports FCBD! That should take care of the fuel cut. Oh, wait, it's not even plugged in!
Question: Why would someone go to the trouble to buy and install a fuel cut defenser, but not use it? Do these things cause some sort of problems?
Alright, there's the boost gauge sensor, but the hose is split. Snip snip, all fixed. The zip tie it's hanging from is lame; I'll mount it properly. What are those two hoses there? They are suspiciously not factory looking and run into the cabin sloppily. I can't see where they go under the engine, but they are on the hot side near the turbo. Head under the dash, feel around, found em, follow along, a little further, THERE IT IS! Boost controller. I knew it. It's one of those ancient no-name models and the knob is snapped off, wow. Yeah, that's coming out. There's no need to turn up the boost on this car within the stated purpose of it and that's just going to exacerbate the knock and make the motor wear out quicker.
