[Vwdiesel] Ways of cooling an AAZ

[Pablo Moretti]

Thanks Doyt,

As an update, I found that exhaust was a bit too thin, so I took it to the
expert, he told me that the turbo has a blocked valve, so the turbo is been
done at this time, and then we´ll have to change part of the exhaust.
Meanwhile I´ll connect the oil cooler, using the already installed sandwich.
I´ll take a look in the intake as you suggested.

Does anyone have any suggestion of which type/size of exhaust to use? I was
thinking about 2".


Thanks,
Pablo
