Thanks for the info Alexiskayak
Hehe, something along those lines Andy!
I get bored easily, so will probably always be tinkering with something. Good to hear others have been thinking the same, though I wonder why Steve never built it?
Yeah, you have a point with the inlet Yoof. It's certainly possible but could be costly. Carver on CP paid ~£120 to have his GT and ABU manifolds mated. I know a local fabricator who could do it, and hopefully it would be a reasonable cost. Luckily I've a spare GT manifold sat in the garage that cost me £5 so the parts would be negligible. Just thought, the sump would also need either 'adjustment' or (more likely because the oil return is already there) swapping for a Mk3 item to clear the subframe.
£250 should cover the engine and the manifold and I'd build the vernier to save money. Then just any bearings, gaskets, rings needed, depending on the condition of the engine. A fair amount of cash..... but there's a lot of torque.....
