2.0 hdi Turbo upgrade

[Shoezor]

Hi all, I've been a long time reader of piston heads bit this is my first post!

I've got a Citroen C4 vts coupe with a 2.0 HDI diesel engine. I've already has it mapped and currently in the process of putting lowering springs on it.

In terms of my next upgrade to performance I was looking at upgrading the turbo, bit couldn't find any info on the web about it!

Is it as simple as putting a turbo on it from a 3.0 HDI engine? Or is there any other route I can take to increase performance?

Thanks!
