13B REW with 12A Front Cover and Mount - Strong Enough for Big Power?
I have a front mounted 12A front cover/sump on a 13B 6 port in a non-Mazda, thinking about going to a 13B-REW with a turbo. CAS compatibility is not a concern here, nor is the rest of the driveline to deal with increased torque, those things are straightforward to deal with, just integrity of the front engine mount system is what I am asking about here.
So, any issues using a 12A front cover and front mount system with a big power turbo motor? Assuming the 12A front cover doesn't break, what about other potential issues? For example, oil leaks between the front cover and front side housing or the joint between the front cover and the oil pan? Timing issues with CAS due to flexure of the front cover under load? E-shaft nose seal issues due to deformation of the front cover under load? Etc? |
It doesn't make a difference which front cover you use. Whether you are running a huge turbo or not. It is just a cover. your CAS, Eccentric shaft and any oil pan will line up. It is all preference.

I think he wants to mount a 3rd gen engine in an fb or sa and I would say to use the side (fc)/ rear(fd) engine mounts and fab something to tie into the cross member or beefed-up frame rails.

people that drag race only use front cover motor mounts and they're making big enough power i think lol, north of 500 at least

I have seen it done myself but I have seen a hard launch break the front cover. Probably rare but it would be enough to scare me into at least beefing up the front cover at the threaded area.

probably! I didn't see the launch just the front cover.

you might be more likely to crack a iron than a front cover when lots of power and if that happens it might be due to poor dowel pin placment

Old post I know, but I have read it doesn't matter what front cover you use but I have also read you cant because of bolt pattern and CAS. Anyone have any input??
