850 tdi upgrade project - Page 15

Thought I would put a few build pics up as the engine work is just about finished now. My goal is to reach 230-240 bhp and somewhere in the region of 360 ft/lb of torque. I'm still putting a few miles on it before I go all out but my ar5e dyno says it's not far off!

Anyway the build:

All the front end removed ready for the big intercooler. It seems there is even less space than a T5 to wedge a 3" one in but it is possible minus air con.

Manifolds removed to make way for the 16t.

After some swear words the 16t fits a treat. A custom bracket for the actuator had to be made due to the turbo being rotated.

The oil feed and return lines needed modifying and I was quite surprised how much smaller the diameter of the c70 return line is compared to the tdi one. Going to see how I get on without water lines to start with, I have read up on it and asked several experts their opinion and they think it will be fine as a diesel runs a lot cooler.

I will get more pics up over the weekend.
