I'd guess it's not going to be possible too but it wouldn't surprise me if you could do it?

Is this just because you have a 1600 lying about that you could use?

I've seen fitted to a cos a transit block engine, think it was a 202 block? Already a 2l and the whole engine only cost £50. Was a few years ago now though. You'd prob still get one alot cheaper than a 205 tho!
