Small update,

Did some stuff today after a small summer dip.

Radiator and intercooler time!

The standard GC8 radiator is very good, the only problem are the plastic end tanks which are prone to cracking on the seams after a few years.
So i needed to check if I could weld on aluminum ones.
Luckily I had an old radiator somewhere which I could use for experimenting.

If this works I'll buy a new radiator for the real thing.

First bits off:



Endtanks gone and behold a nice weld-able core .






I'm not convinced by the 300 dollar taiwanese FMIC kits somehow, and I'm not the only one it seems.
After talking to some pro's the next best thing to mega expensive rally/race cores were actually cores used in production cars.
Now it was only a matter of searching for the right one.

It has to have the right measurements of course, with as much fins per inch as possible.
Also it should be thin, thick cores are not as good as a thin one with a big frontal area.
Problem is that the air going through the core is at core temp halfway through the core thus not cooling anymore.

In the end I went to a big car scrapyard searching through tons of cores.
I found one with all that I needed, except the height, so I need a second one to weld to this one.
It's from a Renault trafic from 2007.
It also has plastic end tanks, so they need to come off as well.

This is how it looks like new:

Ready for more torture:

The red gasket for the plastic endtanks, check the fins in the core:

That was it for now!
