SVX Engine cooling "Again & Again"

I can honestly say that impeding the flow is not going to help anything except allowing it to overheat on both sides of the engine rather than just the one restricted at this point

I'm just going to make a general comment here about this problem, rather than a specific suggestion for a solution. I'll be watching for the success of what you are doing.

Do we all remember the development car picture with Twin Turbo on the rear corner? And we know that Subaru never supplied the SVX with a manual gearbox, stating that a manual gearbox would not handle the torque, which we long recognise was BS.

Based on the problems we are having here I'm inclined to believe that Fuji engineers were aware of the poor cooling, and the car was released without a manual to keep revs down, and without the turbos because they would add heat.

Note that instead of developing the EG 33, they next produce the EZ30 which in some ways is less advanced than the EG was. As Tony notes above though, the newer 6 cylinder has a better grasp of cooling the block.

Maybe this inhibiting problem was there and recognised by them all along, and they just moved on to a different block to get around it?

Just a thought
