[Vwdiesel] Putting turbo on a na 1.6?

WRT turbo choice on a 1.6TD vanagon, here is some info I previously posted
on another forum:

I have always preferred to have more boost in the lower rpms in order to
help get the big box moving.  I don't tend to rev it high and so having the
boost at lower rpms is important.  The other factor to consider with the
vanagon installation is whether or not the turbo interferes with any of the
engine mounting components and what work is necessary to eliminate that
interference.  There were basically 5 different turbo-chargers used on the
1.6TD and 1.9TD engines and provided the appropriate manifold is used, will
all bolt up to the cylinder head.  They were the T3, K24, K14, T2, and K03.
 The mounting interference issues of the K24, T3 and K14 can be eliminated
using the Quantum/Vanagon exhaust manifold, but that approach introduces
other issues with oil drainage and intake plumbing and so is an approach I
do not favor.

The T3 and K24 have the same (or very similar) boost characteristics and
are both just plain too large for the 1.6TD in a vanagon.  Boost doesn't
start until about 3,000-3,500 rpms and you can literally get stuck in 2nd
gear on moderate grades and even if you rev it to the limit, you cannot
shift fast enough to be above the boost threshold in 3rd and without any
boost you cannot accelerate.  This effect is most apparent at higher
altitudes, but those turbos are irritating even at lower altitudes.  The
K24 and T3 also both severely interfere with the driver's side mounting
bracket.

The T2 and K03 are the smallest of the 5 turbos and share the same (or very
similar) boost characteristics as each other.  Their boost threshold is
below idle and so you will see basically instant boost when letting the
clutch out.  Full boost is developed by 2,000 rpms.  They don't ever give
the punch of the larger turbos because they are always developing some
boost right from idle.  They do restrict the exhaust more than the larger
turbos and so comparatively hurt high-rpm power some.  The K03 when used
with the 1.6TD has a very slight interference with the driver's side engine
mounting bracket which is very easily eliminated.  The k03 does not have
any interference when used with the 1.9TD.  I have not personally used a T2
in a vanagon, but saw someone else's install on a 1.9TD and it appeared to
clear the mounting components without issue.

The last option is the K14.  It is middle-of-the-road as far as size is
concerned.  It is a much better turbo than the K24 and T3.  It flows as
well as the larger ones at higher rpms and yet spools at least 1,000 rpms
sooner.  There is some lag, but you definitely feel the boost kick in more
than with the k03.  The K14 flows better at high-rpms than the K03.  The
K14 is a significant interference with the driver's side mounting bracket
and requires significant modification to the mounting bracket."

The overall performance of the K14 is my personal preference but the
installation is definitely more difficult.  IMO, the easiest way to
eliminate the interference with the K14, is to chop the nose off the
aluminum mounting bracket and then bolt a piece of 3/8" steel to the bottom
of it with an appropriate bend and hole.  Then drop the front of the
carrier bar 3/4" by adding a spacer, and the engine geometry remains the
same as it was.  The slight interference with with the k03 mounted to the
1.6TD can be eliminated by grinding or cutting the mounting bracket
slightly.

To sum up, if you are planning on using a wastegated turbo on a 1.6TD in a
vanagon, DO NOT use a K24 or T3.  Use either a K14 if you don't mind a
little lag and can do the fabrication necessary or use a K03/T2 from an AAZ
with matching manifold for fastest spool with a little loss of top-end but
an easy installation.
