Haha, funny story. So that plate is from racing beat that came with my header that the last owner put on. So when he installed the header he had that blockoff plate put on as well with the ACV over it. When I took my car to a shop to get a couple things checked, they found that, took it off and wrote "DO NOT INSTALL" on it and gave it to me... well when I blocked off all my emissions stuff and ripped it out I still used it. Now it looks kinda runny with a plate on there that says "DO NOT INSTALL"

 

Actually, it's the thermostat the regulates the temperature of the engine, not the fan...

And why would you want it cooler anyway? Mazda designed the engine to operate in a specific temperature range. Keeping it cooler will simply reduce power, increase fuel consumption, and foul plugs more quickly...

 

Yep...Aaron's got it right. There is such a thing as over-cooling a car. If you need a new thermostat in a pinch an autoparts store unit is fine until you can get the OEM mazda piece. I've always used Mazda's thermostat and radiator cap. As for the e-fan, I know this is a popular mod but I never quite gotten the point. The stock fan works just fine and if anything needs an upgrade in the OEM cooling system it's the radiator. As far as I can tell, an E-fan just places more of a load on the FC's charging system which stinks to begin with.

 

all this talk reminds me of another question... later on i will want a upgraded radiator (when running the bottle and a bunch of other mods) i know the stock radiators can hold just about all a n/a puts out right... even blowing a 100 shot right? i want to get one thats not plastic also (main reason im doing it) but i dont want to do what some people call "overkill" and i want the car to run NORMAL.... im sure i can find some out there just all the rads ive seen on n/a's people call overkill... what do you think?

 

Yes I know it is the thermostat, I'm not that dumb

My point was, that there is no "proof" that the stock fan out performs any other one out there, and if it came down to the fact that you *need* to be at a cooler temp than your current clutch fan is providing, then an e-fan with an adjustable thermostat would work great.

 

I've been planning on the koyo, seems like a good unit, all you'll ever need, not a bad price.

 

what did remove? That thing that hooks up to where the throttle body hooks up to (upper intake manifold)? Did my question make sense?

 

radiators for the TII and N/A should be the same as far as I know...beyond 250rwhp a radiator upgrade is probably a very good idea as you now likely have an upgraded turbo, a FMIC (blocking the stock rad) and are generating a load more power and therefore heat.

 

If you're ever in that situation, there is something wrong with your cooling system, engine, or clutch fan. If there's something wrong with the clutch fan, then go ahead and replace it with an e-fan. That's what I did. But if you have another problem somewhere, FIX IT instead of band-aiding it with a different fan.

 

That's where the rats nest stuff used to be, my pic doesnt show it very well. But that blue plug you see, theres actually 4 plugs in all with it (blue, orange, grey, yellow) that used to be plugged into the solenoids that hook to the rats nest (bunch of vac lines) that all went away when I ripped out my emissions junk. Plus there is the BAC plug in that whole mess too since the BAC came off... and finally, brackets used to be there for the BAC

 

Yah I totally understand what you're saying, makes sense. I'm just relaying what other people have said before

I myself am considering the e-fan for spacial purposes, I'm trying to open up my engine bay as much as possible to make it easy to work on things.

 

i never thought of reinstalling the acv over the plate as a stealthy move. hmmm


edit: btw ddub, shouldnt you put a filter on the hose that comes from the oil neck? didnt that originally run to the intake track, it would be a shame for crud to get in there or make a mess when filling oil

 

That used to go to the PCV. A filter? no... What the common idea on what to do with it is to leave it vented to the atmosphere like mine, or to make an oil catch can with a breather on the top of it. Vented like mine might drip oil into the engine bay every so often, so thats why eventually I'm going to make the oil catch can.

 

That stock snorkel to the bumper _is_ a cold air intake. When tuning, we have to ensure what we intall does not snort from the hot bay.

I'm researching my next mod: alternator relocation -- if room, moving it lower, perhaps replacing the A/C compressor if I become so insane.
