Looking for experiences with a VNT turbo on a 1.6TD. I have a rather heavy, '89 VW Transporter Hightop. It was imported from Germany and has the 1.6TD & 5 speed. I have had the engine rebuilt and works well, but we can always use more power :-)
The engine has a K14 on it now and the 'special' exhaust manifold for the 50 degree installation in the T3.
I understand that certain Audi & Passat's possibly European had a VNT15 that was standalone, not part of the exhaust manifold (028 145 702H). The exhaust manifold would require an adaptor to fit the VNT15 and the exhaust would have to be modified to fit. I would have to acquire some system for the VNT control, I see standalone electronic ones are available (ie.

My little 1.6TD has been fitted with a liquid intercooler and runs currently at 14psi, it has a Giles Pump & Injectors. The engine pulls well from 3000 to 5000, but is lacking from idle to 3000. My hope is that with a VNT I could achieve more bottom end power.
Im sure this has been done before... Am I on the right track?
BTW I have an AHU waiting in the wings if required...
