It has 2 turbos, one small for low rpm boost, then the larger one takes over. No Lag at all when used on the Mercs, so should be the same with 300cc more capacity.
They have an exhaust bypass/wastegate between the exhaust turbines, but both are always spinning. And a bypass valve in the boost side between them also.
Seamless air delivery. I have made 2 dawes valves to control the vacuum actuators, and also have a boost pressure actuator from another turbo that i may try also to get the boost curve suitable.
Exhaust Manifold completed. Also support brace that bolts to where one was fitted in its original location. Other end bolts to 2 M8 threads on the side of the Block that were unused.
Most common intercooler upgrade seems to be the double core Allisport ones - fits in the original spot with a bit of squeezing I think, may have to trim the top brace.
If you've got Facebook, and you're not already on it, check the Tdi Performance group run by fourby.co.uk - a wealth of knowledge there and I'm sure they'd love to see what you're up to with this!
