[Es2] things that tend to break on es2's at the track

[Matt twentyV]

I'm still running the stock cq fan and shrouds, with
the 2B radiator, yes it fits.  Dimensionally the 2B is
same as the 034EFI I think the main difference is that
2B duplicated all the stock mounting fixtures (except
for the aux rad connections).  Without actually trying
it, I see no reason the stock bits can't work with the
034EFI radiator too.

I also have the stock 200q oil cooler mounted below
the passenger headlight right in the airflow through
the lower opening in the RS2 bumper.  "Mounted" is an
exageration, but it seems to stay put.

Engine temps reach 130C on mild weather (60-70F) track
days which is about as hot as I'd like to see the
engine get.  I would like to beef up the oil cooler at
some point, and upgrading the rad fan is probably a
good plan too.  Motor is 3B with a chip and exhaust
(stock turbo, 20PSI).

But really, the biggest priority for me for a better
track setup is an oil separator/ catch can.  The stock
breather system recycles way too much oil back into
the intake on hard right hand corners.
