So as I've been struggling to remove the cylinder head I now have one sheered bolt on the turbo as I was just going to lift the head with the manifold but I also found two rounded nuts on the manifold itself from previous owners efforts. So I'm left with two options, scrap it or go balls out and haul the whole engine out. Naturally I've gone for the later as I couldn't be without my R so at some point soon it's going down my workshop once some space has been made and the hard great will begin. Luckily my mate I share the workshop with has offered to help on one condition, full strip down and rebuild with forged internals, bigger turbo etc. Sounds like a plan to me so that's the idea. Finally put all my ambitions for the car in action, may take a while but think its going to be worth it.
