| RB25/RB20(skyline GTST)
High Flow
EXCHANGE
The turbocharger on the GTST Skyline rb20 engine are
a unique turbo as in the components it has are unusual.
The most common are the ball bearing and ceramic
turbine wheel types which are not like the current
GARRET GT turbo's
which are so popular. The ball
bearings system is very different and the turbine wheel
is ceramic.Also the exhaust housing has a very tiny A/R
possibly around a .2 A/R. You can really understand the aim of the NISSAN designers was to create something
with as little LAG as possible.
The Ball Bearing side of
the turbo is reasonably reliable but the ceramic turbine
does not handle the punishment long term
especially
when the boost is raised. The turbine housings small
A/R can cause a high back pressure and also cause
an eccessive temperature
raise in the exhaust manifold
and turbine housing which can cause demage. There
are types of this turbo that have PLASTIC compressor
wheels
which ,of course,do not last but can aid in the
spool up.High Flowing these has a very successful result and there is many levels.
But rebuilding is not
possible to bring it back to original.
