Anthony,
The TB34 is a combination of T3 and T4 components and yes it does bolt on.They
use a T3 bearing housing with a 360 deg screw in thrust bearing.They have a "H"
type compressor housing which look similar in size to the TS04 or the new 400 HP
GT series turbos.The compressor wheel in mine was a 3'' H (20288) but I've been
told they also came with a 2.75" H (20235).The comp housing also had Nissan cast
into it.The turbine housing was a .63 made from high quality steel with a larger
nozzle area.The turbine wheel was a -61 which is what turbonetics refer to as a
stage 2.The actuactor was a 15psi adjustable unit.I've only ever seen one other
turbo like this on a Fiat sports sedan in Perth.I was told that only a handfull
of these units came into the country.There is better technology available now
but this also costs.I've just built up a budget T3/T4 combo for my L series
which should see over 300HP using second hand parts.
