So, after some searching, I manage to locate a Jackson Racing Supercharger from a US based Motorsports supplier, whom after some negotiations, agreed a very good price.

The main kit list:

1. JRSC - DC5

2. 3.4 pulley

3. 630cc injectors

4. Uprated fuel pump (in-line in my case

5. Exhaust Manifold - to remain as is for now 4-2-1 (not ideal, I know)

6. Air filter - K&N Largest I could find

7. KPro ECU

8. New belt (gone for 7PK1200)

Budget target = Less than £3K
