So many ideas so little time... 
I'm still waiting to go home to my bella and start working on FMIC installation. But since I've got nothing to do in the mean time I was surfing all over the web and somehow landed on the TDIclub.com...
A lot of interesting stuff over there. Some insane tuning projects... 300BHP from 1.9L 8V TDIs and stuff like that
:wow:
Anyway what I found most interesting is that this guys upgrade their turbos like we change our oil filters
Most common are upgrades to VNT20 or VNT22 turbos, and some hybrid VNT17/20/22...
But most of that big turbo projects really ruin the cars daily drive ability. Full boost at 2500rpm is really not my idea of a drivable car.
But then I came across the "third generation" of Garrett turbos... the "GTBs"
The GTB1756VK form Audi 2.7 TDI, GTB1752V from Honda Accord or GTB2056V from Alfa 2.4JTD 210BHP...
Those are supposed to spool faster compared to old generation turbos, boost higher, flow easier...
What do you think? How much of a hassle would it be to replace standard GT1749V with GTB1756VK? The main problems as far as I can see is the new electronic VNT actuator on the GTB1756VK, which should be replaced with a vacuum operated actuator.
Otherwise the orientation of the turbo in/outlets is very similar to the GT1749V so I guess there shouldn't be too much of a problem to adapt the manifold and exhaust to fit new turbo.
But the main question is is would the spool up be comparable to the original turbo? I read that this new turbo is good for 230BHP on a 1.9TDI, but for me low end torque is of more importance than 10 or 20HP at high rpms.
