I know mate, the two words don't go together very well!! I am unsure of current exac spec till I've stripped it but it was built by a company called alto automotive iirc and cost him 4k new.
It has an HO inlet manifold , unsure of ex mani but it's cast, hard to get in there till i remove stuff!possibly rst tho .
mtx 75 gearbox I think, pectel t2 standalone ecu, custom harness ... Needs redoing!
Unsure of turbo. 12 psi boost max. no decompression plate, possibly forged internals...TBC

Budget i was hoping max 3.5 k plus cost of new turbo.. I would settle for 350+ Hp but it's got to be worth the effort and cost as its dynoed at 250 on a dyno jet as it is!
