I think there have been a couple (max) Megasquirt P80s. It's doable, but not easy. Fortunately it seems the 10 valve cars have less sensors and whatnot, so it might be easier to adapt? I'm not too familiar with standalone ECUs.
Search on Volvospeed and Turbobricks... you're not going to find that level of modification on this forum.

I'd be real careful about it. Do a lot of research on the company. Make sure they document the wiring/parts/everything. I heard way too many horror stories about a person/shop agree to work, took the money, started on the job, never finished the work.

Personally, I would only do these kind of work myself. I want to know exactly what the components are, where they are installed, and how they are installed. Then I can make wiring diagram, learn how the system work, then learn how to troubleshoot.

Cheers, I've had to persephone it, they told me £1250, but it could cost more, I asked if it'll exceed £1700, and they couldn't answer. So for now, I've scored on a limited edition galant, and will proceed with the T5 conversion it time, think I'm going to look for a banged up t5 and take every single piece and put it in the 10v

Are you between Belfast and Derry? One of my kids is in Belfast for work and I seem to recall passing through on a visit a few years back

My advice is to find banged T5 with good running engine and use parts from 10v to get it on the road.
It would be less of a headache.
