Garrett GT-15 for 1.6TD?
« on: July 19, 2010, 12:45:31 pm »
Have a 1.6TD with stock T3 turbo. Locally a GT-15 is available, factory rebuild, the original application being a 1Z TDI.

First- would this be a good upgrade to the current T3? Faster spooling?
Second - would this be bolt on, or need new downpipe, other modifications?

Much faster spooling. Will bolt to engine with 1Z exhaust manifold. Oil lines and exhaust will need to modify.

USA vnts came with the exhaust manifold pre cast to the turbo.. nothing to worry about there. but you will need to custom fab everything else.

it will physically bolt to the engine, but thats about it. ask me how i know  ;D

The GT-15 is like the K03. You will need to clock the turbo, use a new intake pipe (filter to turbo), new pipe between the turbo and intake manifold, custom oil return line, bend the oil feed line and you will need a new, custom downpipe and the proper exhaust manifold.
