Fitting Intercooler to Pug 306 HDi 90 - Simon (Anne\'s Other Half)

I've just handed back a '03 plate Volvo V40 diesel with the 115bhp lump when I left the company. I am now running about in a Pug 306 HDi 90 that used to belong to SWMBO. It is great on the handling side, but I am missing the extra bhp.

I have read on the forums that the tuning boxes that plug in to the common rail just over fuel and chuck out lots of smoke. These are in the 350 quid bracket, and seem to be a lot of cash for something that cokes up the engine.

Is it possible, sensible and easy to take the larger turbo and intercooler off a scrapped 406 110bhp and fit it to my 90?
Would this produce the extra to satisfy my needs?
What would this do to the ECU? Would the programming in it need to be changed/remapped.

Any thoughts or comments greatly appreciated.

You'd probably find it harder to insure an intercooler and replacement turbo than just simply declaring a chip.

Yes, you would have to change the ECU or have it reprogrammed.

I have a "box" on my C5 HDI 110, it only smokes in 3rd at max revs. Nothing in 1st or 2nd and you can't legally do it in 4th.

Add a shot of Millers DPP and run on Shell Extra. I'm happy with it.
