When swapping the 12a front cover onto a 13BT(s5) Does anything need to be swapped over? I'm Running premix so dont worry about the OMP, I'm also alreay done with a turbo oil return, just making sure im not missing anything...

 

You got it! you can take the shaft and gear out for the omp if you like also.

 

Cool, im just wondering about the oil pressure control valve now, is the 12a one ok in there or should it(can it?) be swapped out for the tII one

 

yah good idea!!
as far as the oil reg. goes the 12a one will be fine

 

thanks, problem solved, engine goes in today!

 

I weled a plate to the front of the engine and tapped 4 holes for the mounting plate.

No swapping needed. Or gaskets etc. Just a thought.

 

Too late, already swapped over the cover, i actually did consider your idea, but decided against just because i had the front cover available... The turbo return is already tapped, OMP blocked off, etc, All that is left for me is throwing the engine in and hooking up my beautiful new microtech!
