[T2] engine oil pump / second oil cooler , engine improvement

[C. Dreike]

A larger pump is not always in one's best interest. The oil passages 
are only so large and the oil must squeeze through the bearing 
clearances. A larger pump could theoretically overpressure the system 
and provide for leaks. A little research may well show that the 
standard size pump is really all you need, especially in a "fresh" 
engine with tight bearings. The added oil cooler will have large hoses 
and passages which will have only a very minor affect on flow and 
pressure drops.

Hey guys ,

First , a big thanks to everyone who help me with advise to rebuild my
engine.

I could not finish my engine on time last week for Yosemite but 
camping
with my kids in a tent with freezing temp was fun ..  I want my camper
back more than ever now :-)

My rebuild engine is going well so far, I just put my case together 
and
can't wait to put the cylinder and head tomorrow.

1) I have the "impure" thought of putting a second oil cooler. Since
there's not much space under the bus and I don't want it to 
transfigure
my van by putting the oil cooler exposed to eyes. I was thinking to 
use
a small motorcycle oil cooler like this one:

This could fit under the bus.

Now the real questions for me is what kind of heavy duty oil pump 
should
I use ?. Budepot has two with 30mm and 26 mm gears. I assume the 30mm 
is
more heavy duty and move more oil, correct ? if so, why the 26mm is 
more
expensive.?

Any comment on adding the motorcycle oil cooler and the difference 
with
the 30mm vs 26mm gears oil pump?  What is your experience adding a new
oil cooler ?

Thanks for any feedback.
