Ok, so I should have been a little clearer about which car. The blue one is the perfect blend for fast road, track and the drag strip so nothings going to change with that setup. 4BOA is going to be a clubman classic with mild/period performance, otherwise I'd just build another blue one and what's the point of that. It's the dayly driver that I haven't got yet that I refer to. LHD, rust free, fully wax oiled, and reliable that I can drive around for work. I can then get rid of the van to make room for the z. I love the drivability, reliability and fuel economy of the 1j but it seams a waiste putting all that power into a car that ill potter around in all day. Also I'd like it to be in keeping with a z so 6 cylinder and probably no turbo. Been toying with the idea of rb25 na or maybe with carbs.
