des...i saw sum1 selling mivec t.body rm 250....engine n performance segment there...
then u need 2 take ur ori manifold n then go machine shop ask them 2 bored it 2 60mm...mivec size...
since ur sending ur manifold to engineering shop to port match the plenum opening to 60mm, i suggest u port match ur runner openings to the gasket size as well. one shot kasi buat ler :)
