Here is one that I've cut but haven't welded up yet.

So Petert is it possible just to delete all that steel pipe that runs along the back of block? Doesn't negectively affect coolant circulation at all? Always keen to delete unnecessarys on the race car.

What is the an outlet used for? Return from the expansion tank? You have deleted the cabin heater? Always learning new stuff - Great.

Definitely. It’s only there as the heater matrix bypass, when used with a two stage thermostat. On a race car, you want all the coolant going in one hole and coming out one hole.

No heaters in race cars.

Thanks. The inlet on the end of the engine has also been welded I assume? My engine is running hot Will deleting the heater matrix cure that?

find an aluminium XU10J4 entry block

Does it bolts on the alloy block?

I wonder as well, it looks from the pictures that the water housing from Peter has opposing bolt holes. Just like the GTi6 one. While the XU7 one is offset.

 

Maybe this can shed some light on it.

Ah! My bad. Yours is an alloy block. The XU10J4 will never fit. Can you use an alloy XU5/XU9 block?

When I needed one for my XU9J4 it looked into it and sadly the XU10J4 one wouldn't fit.

 

As for using an older XU5/9 alloy one they are really hard to weld without leaks, the (pot) metal is fine for sand casting and the like but that's about it.

 

The XU10J4 one is made using lost foam casting and machined to fit the quad ring seal, the alloy is way better and can be welded fine.

I made my own version of this from ally plate and pipe and TIG welded it together as the ones I had or could find either wouldn't fit the block or didn't have the take offs I wanted. It was easy enough to do. I didn't have the milling machine at the time so I sealed it with a gasket to the flat on the block. These days I would probably machine a groove and use the seal ring instead.

Mounting hole position seems identical to XU9J4 outlet. So likely the other Xu9 will fit as well. 

 

On my trackday 205 I blocked the return from the thermostat housing and removed the heater matrix. So no flow if thermostat is closed and only flow through te radiator if it opens up. The temperature reading on track is rock solid. (Better than my other 205's)

I had one 3D printed in metal but it was pricy. TIG welding or even brazing can be much cheaper if you do at least part of the work yourself.

As for the gasket the older aluminium housings had a paper gasket (1340.10) so there is enough of a flat surface on the block to use one.
