12a question

fc nut · 05-14-2012, 07:26 PM

my sons se had a carbed 12a in it.I'm planning on using my se housings and rotors when i build his engine. i've looked at the 12a's oil cooler and was wandering, do I need to use the beehive or can I use an s4 cooler instead?

Swap it.

The 12A in my 79 used an oil cooler almost identical to the one in an FC. I don't know about internals or the fittings, but I don't see why not. I still have the oil cooler and front cover from the 12A, if the FC one won't work. Anyone else?

Don't use the beehive for a 13B build. You want a front mount of some kind.

The 2nd gen oil cooler works the hard line for the back iron has to be straightened a little to fit then you will have to figure out a way to mount it

as long as you can figure a way to mount it, use the S4 cooler.

Mazda did so well at most parts ... but that beehive is such a joke

swap it.

recently my se's oil cooler was cracked and i was gonna use an s4. i ended up getting it welded,so i was gonna use it in my sons car. his engine is gonna have se housings and 12a irons,that's why i was gonna see if it would work.

I think my question is related:

I just recently replaced my sp 12A (lost compression) with a stock 12A. It was running the "bee hive" cooler so I pulled it already and am running a front mount. Can the hard coolant line that's still back there be unscrewed and that port plugged or ...? I didn't want to attempt to remove it yet and potentially shoot myself in the foot and introduce a new problem that didn't exist. Right now I've capped both openings but they're still leaking a bit.

Here's a picture of what I'm talking about with the orange arrow pointing out the hardline I'm referring to. (it's not my engine by the way):

i think those r just pressed into the housing. last one i did i just cut it off just behind where it T's off towards the firewall so there's just the single piece sticking out.

thanks for the input,however i've decided to use my se engine in my son's car.

rxtasy3 · 09-15-2012, 09:55 PM

use an original SE cooler if u can get one, otherwise as mentioned, u can fab a mount for the s4 cooler.

IH8DSM · 09-16-2012, 09:40 PM

Just cap one of the ports with a cap they sell some in the help section of auto zone that are just for blocking coolant. You could always bend it and weld it shut.

fc nut · 09-17-2012, 03:28 PM

i ditched that idea. i'm gonna use my se engine in my son's car,with a sidedraft setup. i'm gonna use the s4 cooler on his car.
