front covers.... 89 13b swap
Hey I'm debating which front cover I want to use for the swap here. (I'm putting an 89 N/A 13b into my 12a 85 GS)
I got the mazdatrix mounting adapter in the mail yesterday. Now from what I heard I have to use the 12a front cover for the engine to mount correctly. How ever the 13b front cover bolts up perfectly to the mounting adapter.
I dont know exactly how the mountings are layed out and how they work, (i havent pulled the 12a yet) but why couldnt I use the 13b front cover?

huh?????
the only explanation i have to offer is that maybe someone changed the front cover on that motor before you. the '89 engine's front cover should not have bolts there ... it mounts from the center intermediate housing.
do you have any pictures of it?
BTW ... it is not absolutely necessary to use the 12A front cover, the 84-85 13B front would be your IDEAL choice ... the 12A is just cheaper since you already have it in your possession - that's all.

My 12A front cover on my S5 TII engine looks like that including the oil fitting. Except mine has the turbo oil return added.
Now stop worrying about it and go install the engine!
In regards to the oil cooler, just use a S1 or S2 RX7 cooler. It's probably easier and then you know it'll have suitable fittings.

well the 12a front cover uses a 2 hose oil metering pump and the later 13b uses a 4 hoes oil mettering setup, the bolt patterns are different so you cant pump a 12a pump on a 13b cover etc etc.. as long as you are oging to pre mix i wouldnt worry about ti at all.
