Hey guys, new on here and found some cool stuff, great to see a close knit community of guys helping each other out instead of slagging off at each other !! Awesome to see!! Anyway, have been going through my shed with years of junk in it and have found a head with a turbo inlet manifold, exhaust manifold, turbo, Carby and crossover pipe. Have done some some research and looks like it is Sigma! Now don't laugh, but my eldest boy has decided he likes Geminis so that is what we are doing for his first car so this is surplus to requirements, any idea what it is worth?? Only thing missing is wastegate from bottom of cast manifold that I can see, can take photos if needed. Appreciate any help guys!! Thank you!!
