Hi,

I have a 86 FC with a 13B-RE. I'm using the stock twins with a S4 water pump housing. I have some coolant routing problem.

On the RE water pump housing there is a path that goes to the twin turbo and there is a path that goes to the TB. The exit of the TB goes to the rear of the engine block. Probably that coolant goes to BAC valve but I don't have it anyway.

But since I put the S4 water pump housing I only have one path instead of two that goes somewhere(??) and a path for the return of the twins. I don't know how to route the coolant path.

Should I do the TB mod to simplify things ?

Thanks

 

Why not split the coolant feed and return lines back to the water pump housing?

Yea I think that's a good idea. Thanks Ted!

Can I use a T or something like that? I guess no since there will be too much pressure.

 

Yep, T would be fine.
Just make sure the turbo are on the straight ends and the (coolant) inlet is on the branch.
This ensures the most balanced coolant supply.

Return would be vice versa.
